Until a few years ago, mummy-shaped sleeping bags (sleeping bags) for sleeping in mountainous areas were the mainstream. Although mummy-shaped items are still very popular today, there is an increasing lineup of quilted sleeping bags designed to be lighter.
we have tested 20-DEGREE QUILT from HYPERLITE MOUNTAIN GEAR, which is an unbelievable brand when talking about UL (ultra light), The 20-DEGREE QUILT was an indisputable sleeping bag with the three characteristics of "heat retention," "lightness," and "compact." This sleeping bag is something you'd want to stay in forever, even if it's time to leave your sleeping bag and start taking action.

Main features of HYPERLITE MOUNTAIN GEAR 20-DEGREE QUILT
HYPERLITE MOUNTAIN GEAR (hereafter referred to as HMG) is a brand that deals in America, the birthplace of long trails, and deals in lightweight, durable backpacks and tents. The 20-DEGREE QUILT made by HMG is a quilted sleeping bag that is included in DWR-processed (durable water-repellent) 7D micro ripstop nylon with DWR-processed 1000FP goose down, and also includes short, regular and long sizes, allowing you to choose from the user's physique.
20-DEGREE QUILT boasts high heat retention of -7°C, high quality goose down, and is made from ultra-thin 7D (denier) fabric, and is a portable quilted sleeping bag with a weight of 570g by eliminating the hood and zipper.
The back comes with two special straps to secure the sleeping mat, preventing it from slipping between the mat while sleeping. If you want to further increase confidentiality, attaching bungee cords or other cords to the four loops located on the outside will increase confidentiality and prevent cold air from entering your back.
The 20-DEGREE QUILT is made from the highest quality materials, and is a balanced balance of heat retention and portability, making it a quilted sleeping bag that can be used for hiking scenes for three seasons (for low mountains all year round) and through-hiking on long distance trails.

Impressions using 20-DEGREE QUILT
The fluffy and pleasant 1000FP goose down has excellent heat retention
The 20-DEGREE QUILT uses 1000FP goose down, which is just so pleasant. The moment you enter, you will be wrapped in a supple down, providing excellent heat retention. The 1000FP down is the highest-class number of downs available on the market at the time of this article. (Fill power is one of the criteria for evaluating down performance, and represents the restoration power of 30g down under certain conditions. The larger the FP number, the higher the performance, and the same weight can fill more space.)
The 1000FP super-slim down uses 7D ultra-thin micro ripstop fabric, which also encourages flexibility.
the 20-DEGREE QUILT is -7℃. The amount of down contained is 398g, which is a value that would make anyone who has used a sleeping bag to a certain extent wants to suspect. 20-DEGREE QUILT has the same operating temperature as a model with a highly sensitive mummy-type sleeping bag that has the same amount of down content . In fact, quilt-shaped sleeping bags often have the same heat retention as mummy-shaped sleeping bags, and the big difference between quilt-shaped sleeping bags and mummy-shaped sleeping bags is that the hood and back are abandoned, so more down is placed in places where insulation is required, such as the torso and feet, providing maximum heat retention. And the use of the highest quality down improves the heat retention. (Since quilt-type sleeping bags cannot be measured using the European gnome using the inspection mechanism, the operating temperature values are calculated by each company's own unique calculations, so it is better to consider them as reference values.
No matter how high quality down is, down cannot be used to keep it warm unless it expands. The down is crushed in the area that is grounded with the sleeping mat, so it cannot provide heat retention, so this quilted so it's a quilted sleeping bag with a back part (some quilted sleeping bags have a back side).
The attached attachment strap allows you to secure it with the sleeping mat
Attach the included strap to secure it with the mat
The open quilted sleeping bag on the back is assumed to be on a sleeping mat. If it slips off the mat, its heat retention will suddenly decrease. Two rubber straps are included that can be attached to the back buckle, so you can use them to secure them with the sleeping mat and prevent them from slipping.
The attached strap will inevitably have a gap at the connection part to the sleeping mat. When using in low temperature environments, if you want to further increase confidentiality, there are four loops on the outside, so you can secure it with the sleeping mat using a bungee cord or something similar to secure it firmly in place between your body and your sleeping bag.
To increase the sensitivity, you can attach a bungee cord or something to the outside loop to secure it with the sleeping mat.
In fact, in field tests, I was able to stay in an environment of around minus 5°C without feeling the cold. As it is a hoodless and quilted shape with an open back, it is a must-have for the head and back. The ground and the back of the installation are firmly insulated with an air mat, wear a down jacket, and take precautions such as wearing a knit hat, so it seems that the operating temperature displayed on the main unit is generally correct. However, it is best to consider the lower limit temperature of -7°C, which is set to the operating temperature, to be the operating temperature.
Although it is a quilted type, it has a high spec operation temperature of -7°C.
The footbox is also made using a three-dimensional method, and the down is firmly sealed in, so it keeps your feet warm. Although we did not use covers in the test, we were able to use them actively in environments ranging from 0 to -5°C by wearing clothing to suit the environment and using the cover and innerwear together.

These days, the way you stay at your lodging has become more diverse, so tendo is not the only way to stay in nature. I sometimes use a hammock when I sleep, but hammocks and quilted sleeping bags go well. The hammock is floating in the air, so trying to get into a mummy-shaped sleeping bag is more difficult than you imagined (same when it comes out), but with a quilt, it was easy because you just hang it after lying down.
Hammocks and quilts go well together
I'm curious if there's a bias in the downside
It has excellent heat retention, but one thing that caught my eye was the structure on the top of the sleeping bag. It has a long vertical structure, and according to the official page, it is locked down to prevent it from moving from a designated location, but I was concerned about whether the downward bias would occur due to use.
I shined light on my sleeping bag and took a photo from behind. A cold spot where you can see through is not a down
20-DEGREE QUILT , but any down sleeping bag can cause unevenness in the down, so you can prevent cold spots by getting used to it before use and removing the unevenness in the down before using it.
Quilted type that is easy to ventilate in hot weather
Quilted types are less confidential and the challenge is to block the intrusion of cold air, but in other words, the advantage is that they are easy to ventilate and easy to control in hot weather.
Compared to the mummy type, it is less confidential, but is easier to adjust to heat and stuffiness
In the first place, the scene where you choose a quilt-shaped sleeping bag is not used in harsh environments such as snowy mountains in the harsh winter, but is probably a little more gentle than that. For example, it can be used in early summer to autumn, or in areas where snow does not fall even in winter. In these areas, the author often feels heat and stuffiness, and controls his clothing rather than the frequency of freezing in the cold. A quilt-shaped sleeping bag can be used like a futon, so it is less likely to get stuffy and allows you to sleep comfortably.
You need to get used to going in and out
Buckle on the back. It's small so I struggled a little with connecting until I got used to it.
The 20-DEGREE QUILT has no zippers and only three connection parts on the back . For first-time users of quilted shaped machines, it takes a little time to get in and out. It's a tough task to hold the small buckle behind it inside the sleeping bag. Compared to the mummy type, which can be used by anyone regardless of who uses it, the quilt type has a slightly more quirky feel, and can be said to be for experienced users.
Cold air gets in when you roll over
The 20-DEGREE QUILT can cover the neck firmly , but it cannot prevent cold air from entering due to movement during sleep. Movement such as when turning over in bed creates gaps and cold air enters. This is a good ventilation if the environment is not that cold, but it can be a troublesome problem when you want to shut out the cold air in a low-temperature environment.
Especially when you're sleeping and lie down on your side, if you leave your sleeping bag as is, cold air can enter through the back. Once you get used to it, you will be able to minimize the intrusion of cold air when you roll over, but when using in low-temperature environments, you need to ensure that it is fixed to the sleeping mat and take measures to block the intrusion of cold air as much as possible.
Lightweight and compact despite its high heat retention
Measurement is taken out beforehand by removing the weight of the storage bag.
The 20-DEGREE QUILT weighs 570g (regular size). It is definitely the lightest sleeping bag that can be used up to -7°C. A sleeping bag with a similar temperature for mummy-type sleeping bag is about 800-900g. The two have different structures and cannot be compared in general terms considering their versatility, but when comparing the operating temperature and weight alone, the lightness of the 20-DEGREE QUILT
The sleeping bag is a heavy and large item that competes for one or two of the equipment. Choosing a thin sleeping bag can reduce weight, but it increases the risk of getting cold. After reducing the weight and choosing a thin sleeping bag, the nights are too harsh to withstand the cold (I've already tried it)
It's light, small and warm. 20-DEGREE QUILT solves these problems with sleeping bags .
A storage bag is included, but no storage bag is included
The storage bag included. Can be stored without damaging the down
the 20-DEGREE QUILT comes with a storage bag for storage , but a portable storage bag is not included so you will need to purchase it as an option or have it ready separately.
Compressing allows you to put it in a rather small storage bag, but excessive compression can stress the down, so it is recommended to have a slightly larger storage bag that is easier to store. I use it in a bag with a capacity of about 10L.
Comparison with a 500ml plastic bottle. It can be quite compact
Summary: In terms of functionality, the sharp quilted shape can be conveniently used depending on how you use it!
The quilted sleeping bag with a hood and zipper removed and the back is an open-shaped item that is definitely not easy for everyone to use, but what you can get is its "lightness."
A sleeping bag is one of the most heavy tools you can carry. The weight of the sleeping bag will have a significant impact on the total weight, and for people who understand the characteristics of the tools and can use it in a way that suits their own level, this "lightness" will help them walk more freely and further away.
I have made many mistakes in reducing the weight of my sleeping bag, but the 20-DEGREE QUILT was a sleeping bag that I can confidently recommend for hiking scenes in mountains during the snowless season!
