Review: A must-see for runners and hikers! New wear that is comfortable to wear at any moment Mountain Hardwear Core Pre-Shelf Hoodie

Windshell? Softshell? An all-new windproof jacket has arrived

It has always been common to wear a jacket that is lightly worn to keep out the cold wind, or a windshell.

However, although it is lightweight and compact, it is generally comfortable to wear and makes a crunchy sound. And when I start sweating a lot, I can't help but worry about the stuffiness inside my clothes. Although I was convinced that it was that way, I ended up only in the cold winters and the rainwear was becoming ultra-lightweight, so I was already seeing less and less of a lot of use for myself.

However, Kor Preshell Hoody , released by Mountain Hardwear , was a shocking sensation that completely overturned this image. Despite being a lightweight and windproof jacket like a windshell, it is surprisingly easy to move around, comfortable and not stuffy like a softshell. From the start of your run, you can continue wearing it in any situation when you are on a trail, such as when sweating during climbing, or when winds are strong. This is a new type of shell that eliminates the need for any category, whether it's a windshell or a softshell. We'll be bringing you a review of how I actually tried wearing this piece, which I can no longer let go.

Detailed review

A fabric with a balanced balance of lightweight, windproof, ventilation, water resistance, stretch and durability

The PERTEX QUANTUM AIR, which is used in this jacket, is characterized by its high level and balanced features that are necessary for high-load activities in a short period of time. The thin fabric is so light that it can pass through, making it lightweight and highly breathable. The high density of yarns below 20 denier are knitted to provide windproof and durability.

It is treated with DWR (durable water repellent), so it can be used without any problems in some rain or snow.

The exquisite stretch keeps the tight silhouette from flapping, yet still doesn't hinder movement.

Lightweight not to worry about wearing it

The official weight is 140g (size M). When I actually measured it, it was 123g (S size).

Necessary and sufficient pockets

There are three pockets in total. There are one zippered hand pocket on each waist. The zipper is made of YKK concealed zipper, which contributes to its smart appearance.

On the inside of the right is an inner pocket for packables, and if you put the main body inside it, it fits in the palm of your hand.

When stored in an inner pocket, it becomes the size of your palm. It may not be the smallest of modern windshells, but it's small enough to be in a pack. There is also a loop, so you can also fasten it with a carabiner.

Sleeves and hoods are designed to provide a comfortable fit and windproof finish.

The hood fits perfectly on your face and prevents wind from entering. There is no drawstring or other drawstring, and partially elastic is used to provide elasticity. There is a chin guard on the chin so the zipper won't hit your face.

The cuffs are a little tight, but thanks to the elastic and the stretch of the fabric itself, it doesn't bother you and prevents wind from entering.

Impressions from actually using it

The moment you put your arms through the sleeves, you will be amazed at how light and supple it is. I've had many opportunities to wear windshells, but due to the processing that improves windproof properties of the fabric itself, the sleeves were not good, and the sweat made me get sticky and my arms tense up, causing me to wear them. However, the core pre-shelf hoodie has a very good sliding feel when you put it on, and it feels like your arms pass through smoothly. It feels like a lightweight softshell. You'll probably never know until you try it, but it was one of the most pleasant things I've seen.

Although the overall design is tight, the entire fabric stretches well, so you can wear it without any strain by swinging your arms or twisting your body. I'm 173cm, but the S size fits perfectly. However, it is a tight fit, so if you want to wear it a little looser, size M would be the perfect fit. Also, there is no shaking noise that is common when swinging your arms while running, so you can concentrate on your running.

Despite its highly windproof properties, it has an outstanding sense of sweat. In this season, a windshell with too much windproof properties can easily be worn and moved when you feel chilly, and you'll quickly become stuffy and want to take it off. However, the Quantum Air, which is used for the fabric, is made of a material made by woven 20D yarn at a high density, allowing moisture to escape moderately and is very comfortable. On slopes, you can lower the front zipper and adjust it to allow moisture to escape. The lining is also uneven and does not get sticky.

On the other hand, compared to a full-fledged windshell, although the yarn is woven at a high density, it seems to be slightly less windproof in scenes where strong winds blow. The water repellent is moderate, and of course it will become more visible if it is hit in the rain for a long time, but it can be played without any problems with light rain.

The measured weight is 123g for the S size, which is lighter than a lightweight windshell! That's not to say so. However, considering its durable and supple fabric, outstanding sweat removal and stretchability, it would be a very valuable few tens of grams compared to just a light nylon windshell.

Summary: Recommended for people like this

This completely new jacket combines the good points of wind shell and soft shell, which is light and supple, stretchy and easy to move around in, and also prevents wind and allows you to get rid of sweat, making this a completely new jacket that trail runners like me will not be able to let go. Of course, it will perform best not only for running, but also for high-load, sweat-intensive activities such as speed hiking, cycling, and climbing, where you repeatedly stop and go. Even in summer, it can be used well on mountains where the altitude is high and wind blowing, so how do you use it depends on you. This is a very versatile jacket. It's also good that there are many different colours.

This new type of windshell will become addicted once you put it on. Please give it a try.
