Ultralight hiking is about walking longer, faster, and easier by using minimal equipment and carrying as little weight as possible. While it was once an activity supported by a handful of small cottage brands (small-scale manufacturers of cutting-edge, niche products) and passionate enthusiasts, it has gradually gained popularity alongside the rise in interest in long trails and thru-hiking. Now, manufacturers of all sizes around the world are producing tailored products, and the trend is spreading even further
The Betalite 45 which I'm introducing today Black Diamond (BD), a global manufacturer of products for aggressive mountain activities such as climbing, ski mountaineering, and mountain running . When I first saw it, I couldn't help but be amazed by its cutting-edge specs and cutting-edge approach, which seemed to be taking on the ultralight backpack category, which had previously been the domain of smaller backpack manufacturers. Now that it's available for pick-up at mountain specialty stores nationwide, rather than at select core stores or online stores, it's sure to excite not only ultralight style enthusiasts, but also outdoor enthusiasts who have been wary of such cutting-edge styles until now.
I was able to try out a sample of this ultra-lightweight backpack, which BD's official promotional video proudly describes as "Black Diamond's answer to the fast pack style," so I'd like to share my review after walking the trail a few times

Key Features of the Black Diamond Betalite 45
The Black Diamond Betalite 45 is an ultralight backpack designed for minimalists who want to travel long hiking routes as lightly and quickly as possible. Its body is made of ultra-lightweight, durable, and highly waterproof "Ultra 200" fabric, weighing just 890g fully loaded. This weight can be further reduced to as little as 521g by removing the straps and frame, meeting a wide range of minimalist needs. Two aluminum stays provide excellent load stability at the back, while mesh padding on the back, shoulders, and hipbelt provides moderate cushioning and breathability for comfortable carrying even during long hikes. Other features include running-vest-inspired shoulder straps for a snug fit and excellent storage, as well as a large-capacity stretch mesh front pocket, side stretch pockets, and waistbelt pocket for quick access to your belongings while on the move. The 45-liter capacity is ideal for lightweight multi-day tent hikes, and the separately sold " Betalite Satellite Bag " designed specifically for this pack offers even greater storage and convenience.
Favorite points
- Lightweight, tear-resistant and durable body material
- Highly waterproof construction with waterproof fabric, taped seams, and roll-top opening
- Convenient storage and comfortable shoulder straps
- Breathable and comfortable fit for a comfortable carry
- Large front and side stretch pockets
- Numerous removable parts allow for customization to minimize weight
- Expandable for even more convenient use when combined with the optional satellite bag
Points of concern
- The load lifter straps on the shoulders tend to loosen easily during movement
- It is stable against vertical loads, but is somewhat weak against lateral movement, so the pack tends to shake when carrying a heavy load
- The side stretch pockets, which are prone to wear, are not made of Ultra 200 material

Detailed Review
Weight and durability: The body is made of cutting-edge "Ultra Fabric" for both lightness and strength
In recent years, Challenge Sailcloth's ultra-lightweight fabric, Ultra 200, has been gaining a lot of attention as a material often used in cutting-edge lightweight backpacks. Until now, this high-quality material was only seen in models made by garage manufacturers with relatively small production runs, but what's noteworthy about it is that it's used generously in the Betalite. Let's start by talking about this material
For those unfamiliar with the term, Ultra Fabric is a woven fabric containing UHMWPE (ultra-high molecular weight polyethylene, commonly known as Dyneema) with a laminate backing. It is an ultra-lightweight, waterproof textile with extremely high abrasion and UV resistance. It is several times stronger and more abrasion-resistant than Cordura nylon, and is said to have the same or greater durability per weight as DCF (Dyneema Composite Fabric), which has traditionally been synonymous with lightweight, highly durable fabrics
Also, Ultra fabric comes in thicknesses (from thinnest to thinnest): 100, 200, 400, and 800. It's worth noting that this pack uses standard-thickness Ultra 200 for the main body and Ultra 400 for the bottom part, which is subject to heavy wear. While many ultralight brands these days use Ultra 100, BD has chosen 200 fabric, achieving a good balance between durability and weight rather than going too far with weight reduction
Incidentally, the manufacturer calls it "Ultra 200," but strictly speaking, it's an updated version from the original fabric, with a thicker laminate and an X-lattice reinforcement on the lining (some places seem to call it "Ultra 200X"). This version is slightly heavier than the original, but the tear strength, rigidity, and durability of the fabric are higher
The texture of the fabric feels more supple (fabric-like) than the stiff, rough feel of DCF. However, it also has a moderate stiffness, making it easy to stand up as a backpack and easy to pack. This is a clear difference compared to my previous backpack, the Durston Kakwa 40, which uses Ultra 200, and Betalite's Ultra 200 fabric is easier to handle
The lining is laminated with recycled RUV™ film, which gives the fabric excellent waterproofing, and the seams of this pack are also securely taped (see photo above). This provides extremely high water resistance, preventing rain from getting in unless the pack is submerged, so you can rest assured that the inside of the main compartment will remain safe even in bad weather
In this way, this backpack is not entirely focused on "lightness," but rather is designed with consideration given to durability and protection that will not break even if handled roughly, so it is actually not extremely light. However, the weight of "890g" for a 45-liter capacity is actually light enough that you don't even notice it when you hold it, which is exciting. It is so light that it could be called a daypack. Moreover, there is a sturdy frame on the back that can withstand a load of approximately 18kg, and the fabric is very strong, so comfort and durability are not sacrificed in any way. You can feel the care that went into making this backpack so that anyone can use it and experience the benefits of "lightness" with peace of mind
Comfort and Stability: Well-crafted, comfortable back panel for a perfect fit and excellent breathability
When prioritizing the lightness of a backpack, the comfort of wearing it tends to be neglected as a trade-off, but this ultra-lightweight pack has been carefully developed and is made with meticulous attention to detail, so it never comes down to "it's light, so comfort has to be sacrificed."
Two flat aluminum frames and a back panel with built-in foam padding
The back panel, shoulder straps, and hip belt are made with the know-how the company has cultivated in running packs such as its "Distance" series of backpacks for speed hiking. Made with a highly breathable mesh that quickly dissipates sweat and thin, snug-fitting foam, they allow you to stay comfortable for long periods of time without sweat accumulating. This careful construction is something that garage brands have a hard time imitating, and it's one of the things I'm very pleased with this time
Comfortable and convenient shoulder straps for fast movement
The shoulder straps are not like those of a mountaineering backpack, but are a running vest-style harness. The lightly padded and breathable straps fit securely with two height-adjustable sternum straps, preventing movement while running, and allowing easy access to the various pockets. This is the perfect configuration for fastpacking. However, on the other hand, those who just want to take a leisurely walk may find something softer and thicker with more cushioning more comfortable
Frame structure with high vertical load stability
The internal structure of the back panel is made up of an EVA foam frame pad and two aluminum stays. This allows the back to remain flat regardless of the shape of the load, and the weight of the load is properly transferred to the hip belt, achieving a load capacity of approximately 18 kg, which is sufficient strength for the load. However, if I were to be picky, I would say that this frame (and the hip belt connection structure) is not very resistant to lateral (rotational) movement, and I feel that it would be more stable if the hip belt could pull the entire bottom of the pack closer to the waist and secure it in place
Furthermore, the 45-liter model is equipped with load lifter straps on the shoulders, which bring the center of gravity closer to the back and prevent shaking while walking, keeping the bag stable. When I actually walked, I was carrying about 13 kg, but I hardly felt any strain on my shoulders, the weight was firmly placed on my hips, and I didn't feel like I was being pulled backwards or downwards by the weight
However, while the pack's construction was impeccable, the lightweight ladder lock parts used in the Load Lifter unfortunately didn't work very well. Even when I tightened the straps tightly and started walking, they would suddenly lose all tension, forcing me to constantly re-tighten them. I suppose if the tension was always in one direction, they wouldn't loosen, but as I walked and my body swayed up and down and side to side, they gradually loosened. It's not a part that can be easily replaced, which is a shame considering the overall design is solid (though you could try replacing them with third-party parts like this one
High customizability with removable parts for further weight reduction
The basic feature of this model is that it uses cutting-edge ultralight materials while being beginner-friendly, but that doesn't mean you can't pack it in a truly ultralight style. A clear example of this is that this pack can be significantly lighter by removing its main parts. By removing the foam padding, the two internal aluminum stays, the hip belt, compression straps, and other straps, the weight can be reduced to a minimum of 521g. Personally, I don't want to lose comfort, so I don't intend to go that far, but even with the aluminum stays removed, it still has a load-bearing capacity of 12kg. It's not at all unrealistic to pack it in a truly ultralight style
Storage and usability: Smart storage that remains above average even when pared down to the bare minimum
Main storage
The roll-top main compartment is highly waterproof, preventing rain and dirt from entering, and the capacity can be easily compressed or expanded depending on the amount of luggage
There is a hydration sleeve on the back (without omission), and a hole in the center for the tube to come out (see photo below). The shoulder straps have elastic to secure the tube, making it very convenient for those who use hydration packs to stay hydrated
External storage pockets that are easy to access even while on the move
Designed with fastpacking in mind, the Beta Lite offers convenient storage that's easy to access while minimizing clutter
For example, the front has a huge mesh pocket that looks simple but is quite stretchy, and can easily fit bulky clothing such as rain gear and cold weather gear, as well as flip-flops to wear at the tent site (see photo below)
The side pockets are also quite large and easy to use, following the trend of the past few years. They can easily fit a Nalgene bottle and a 500ml PET bottle (see photo below). However, I'm a bit concerned that the material of the side stretch pockets, which are the most protruding, isn't Ultra 200. It would have been nice to have some material to prevent chafing
The upper sides also feature removable Dynex® compression straps, allowing you to securely fasten long items such as trekking poles, tent poles, and tripods
The shoulder straps feature smart storage options inherited from the company's Distance Series (see bottom left photo). The stretch mesh pocket on the left chest is the perfect size for a vertically sized soft flask. While it's not impossible to fit a 500ml PET bottle, the straps tend to bulge out too much, so we don't recommend it. The right chest has a zippered mesh pocket that's perfect for storing a smartphone, and an open pocket in front of it for small items like gels. These are perfect for storing anything you want quick access to while on the move
The shoulder strap is simple yet versatile, with three different compartments for different uses. As shown in the photo below, you can easily store your smartphone in the open stretch pocket on the right, so it won't fall out. This makes it easy to access your smartphone when you need to quickly check a map, making it extremely convenient (see photo below)
The removable hip belt has three-dimensional pockets on both sides that are easy to operate the zippers (see photo below). It's not particularly large, but it's big enough to hold small items, and I could just about fit my large 6.7-inch smartphone in it (with the phone cover removed), so it wasn't too small
The bottom of the pack is fitted with the same removable Dynex® compression straps as the ones on the sides (see photo below). While seemingly simple, this strap serves three purposes: compressing the pack, storing bulky items like mattresses, and providing loops for securing trekking poles and axes
Satellite bag sold separately for even smarter storage
Although it has plenty of well-thought-out storage for an ultralight pack, it does have some minor inconveniences compared to a regular hiking backpack, such as the lack of a rain cover. However, the separately sold Betalite Satellite Bag not only solves these inconveniences, but also quickly transforms it into a convenient backpack
It's basically a simple pouch, with a sleeve on the back that can be used as a waist pouch, and loops for attaching straps in various places, allowing for various carrying methods such as adding an extra pocket to a backpack or using it as a shoulder bag. The inside is very simple, and when you open the zipper, there is a large space inside that can fit a 500ml PET bottle, with a simple divider
The backpack has a loop on the front for attaching this sub-bag, so it can be used as a rain cover, or it can be attached to the open loop on the sternum strap on the front and used as a front pack
Summary: A groundbreaking backpack that opens the door to the cutting edge of ultralight backpacking for everyone
The Betalite 45 Backpack is made with the highest quality lightweight and durable materials, which have been difficult for large manufacturers to adopt due to material procurement issues. Its stylish design, comfortable fit, and convenient storage make it an appealing backpack. It's an ideal choice for many hikers who haven't had the chance to try full-fledged UL style backpacks until now, opening the door to a new world. Needless to say, this pack is sure to please any hiker who wants to travel "light and fast" (i.e., fastpacking and speed hiking enthusiasts)
While taking into account these many benefits, I personally felt that the fixing strength and stability around the hip belt (ideally, a hip belt structure that pulls the entire pack in from both sides) and the fixing strength of the load lifter were lacking, so people who prioritize a structure that keeps heavy loads stable on the hips and prevents them from shaking, even with a lightweight pack, may be somewhat dissatisfied (I haven't tried it with the 30-liter version, so I'm not sure, but the large 45-liter capacity may also be a factor)
As for capacity, if you're carrying this backpack, you're likely carrying lightweight gear, and in that case, 45 liters is too large for a one-night tent stay. If you plan to stay in mountain huts or take a one-night route, a 30-liter pack will be sufficient. This 45-liter capacity will be fully functional for thru-hikes or traverses of three nights or more, or for climbing streams with ropes and heavy equipment. If you've always thought that ultralight backpacks meant sacrificing comfort and convenience, this is the perfect opportunity to give it a try
