Review: MILLET Breather Toy Hoodie It can be said to be the decisive hit for autumn and winter wear. Active insulation jacket with ultra-water-repellent function
In recent years, heat-retaining jackets that can be worn while you're in the process, such as Patagonia's Nano Air, The North Face's Ventrix, and Arc'teryx's Atom, have been released one after another by famous manufacturers, and have now become fully established as the genre of active insulation
Active Insulation is basically a jacket that is filled with padding and is warm and warm, but at the same time it is breathable and highly stretchy, making it a jacket that can be worn comfortably while maintaining heat even during heavy sweating activities such as trail running, ice climbing, and backcountry in autumn and winter. However, it was originally positioned as a middle layer, and was weak against rain and had to be protected from wet with a hard shell or something.
The MILLET Breather Toy Hoodie we reviewed this time , overturns the conventional wisdom of active insulation, and is a groundbreaking model that is also effective even for use as an outerwear. Here's a review of what I actually tried wearing it.

Detailed review
A jacket that breathes and water repellent
A breathable water-repellent jacket, the catchphrase of the breather jacket . This was achieved through Millet's latest technology.
According to the manufacturer, this jacket is made from silicon-derived water-repellent treatment, which is generally said to have a high durability, but does not cover the surface of the fabric, meaning it does not impair breathability, and ensures strong, highly durable water-repellent performance. BREATHER a fabric made by woven from the yarn, not the surface of the fabric, but each thread is water-repellent .
The photo below shows a lot of water spilled. Perhaps because each thread is water-repellent, it is clear that its water-repellent performance is strong even after just a little trial. It's also resistant to washing and lasts a long time.

It has strong water repellency and lasts a long time. The zipper is not waterproof, so it will bleed when laid flat, but it is not a problem with normal use.
Fits and comfort of the hood, sleeves, and hem
The fit is slim fit, but even I am a bit muscular, it doesn't feel particularly tough, and it has a neat fit. The fabric is a different colour from the inside of the arms to the armpits and the sides of the trunk, but there is no difference in the material itself and it seems to be just a design.

It is filled with padding, so it is a bit bulky, but for that reason it gives a neat impression.
Because the fabric has stretch. That's why, especially the shoulders, thanks to the three-dimensional cutting, the fit fits without relying on the stretchability of the fabric.

The shoulders are cut with a three-dimensional fit and have good mobility.

The inside is made of mesh fabric, so it does not impair breathability and is soft and comfortable to the touch.
The cuffs and hem are made of elastic shirring to prevent cold air and other intrusions. The sleeves are neither long nor short, and are just the right length.

The cuffs are made of elastic shirring to prevent cold air from entering. The 3DeFx+® logo is on the left cuff.
The hood is elastic shirred and does not have an adjustment function with a drawstring or other device. However, the neck is bulky, and if you close the zipper all the way up, it will look like a barracuba that can hide your mouth. The entire hood is elastic and the fabric itself is stretchy, so it's fine to put on and take off even if the zipper is closed all the way to the top.

The collar is high and can cover the mouth, making it useful as a barracuba.
The front zipper opens from both the top and bottom, allowing the heat that has been trapped inside the body to be released quickly.

The front zipper can be opened from above and below, so if too much heat is found inside the body, you can adjust it quickly.
There are three pockets in total: 1 chest pocket and 2 left and right pockets. The zipper on the chest pocket has a small reflector to increase recognition at night.

A reflector is attached to the top of the pocket zipper to increase recognition at night. It can also help others to find your own pocket.
Brushed material is placed inside the waist pocket, making it a hand warmer. The brushed material is placed on the outside to prevent it from being affected by wind.

The inside of the pockets on both waists is made of brushed material, making it a hand warmer.
Impressions from actually using it
The fabric stretches and the padding stretches. All of them are stretched in four directions, making them extremely mobile, and in the active insulation genre, they are extremely mobile, with almost no catches or stress on movement. Even if you warm up by stretching while wearing this jacket, it's unlikely to be bothered. It's so stretchy and highly mobile. Changes in weather reduce the need to put on and take off your clothes, allowing you to concentrate on your activities without any stress.

Thanks to its high stretchability, it is extremely mobile. No stress is required in any movement!
The padding is made of TORAY's 3DeFX+R. Not only is the heat retention, 3DeFX+R is made of ultra-fine coiled threads, so the padding itself is stretchy and the fibers are not dense, so it is breathable.
The padded TORAY 3DeFX+® is of course not a type that has excellent heat retention that keeps you warm even when it is stopped at low temperatures. Taking into consideration this characteristic, the filling amount is not too thick or too thin. It provides sufficient heat retention when it's chilly, and provides sufficient heat retention when it's trembling, so that it doesn't cool your body while moving. It is also breathable so you won't be sweaty. The front zipper in particular can be opened from below, so if you have a faster pace, for example, just open the zipper from below to ventilate. Even if it stops, the moderate heat retention will help prevent the cold. However, it is windproof after ensuring ventilation, so if you stay in a situation where it is exposed to wind for a long time, it will gradually cool down, so be careful about that. In any case, wearing a warm base layer below in winter will make it seem like this enough equipment will be enough to do it unless you go to extremely cold or high-altitude mountain areas.
is the top water-repellent I've worn before It's only natural that it will revive the water, but it will last for a long time! Isn't this waterproof at first? I doubt that. As expected, if the rain is strong, it gradually fades away, but if it rains a certain amount, there is no need to worry. Previously, active insulation has a strong role as a mid-layer, and although it has some water-repellent properties, it was assumed that you would wear a rain jacket over it in bad weather. However, this breather toy hoodie has enough performance to overturn such premises.
The hood is also filled with padding, so if you put it completely on and leave it warms the entire head like the main unit. The hood is a bit spacious and will completely cover even if you wear a brim cap. The helmet is a type that can be worn over the top. There is room to choose from, but it has elastic shirring so it fits well without adjusting it with a drawstring. You won't be flapping when you're stoked by the wind.

Even if you place the cap brim back on, the hood can be completely covered, thanks to its stretchability. The fit is good.
The colour I reviewed this time was orange. It's true that it may stand out and be safe for use in the mountains, but in terms of design, it might be a little more refined in terms of color (although the other colors of BLACK and HONEY MUSTARD can be used in non-realistic situations...). do is MILLET on the right when you open the zipper I think the fact that they make such a appeal is divided on whether they like or not. Another thing is that if the cuffs are thumbhole, it would have been even more perfect as active winter wear? I feel that way. This one seems to be a different preference.

Along the front zipper, there is a furious millet mark...
Summary: It's not just about keeping warm! Three-beat plus one more insulation
There were some very good active insulation I have reviewed so far. the Breather Toy Hoodie introduced this time will also be considered a very good jacket if it is used as a mid-layer.
However, the advantage of this jacket is its multifunctionality, as it combines the functionality that had previously been required to layer. It has solid heat retention and breathability against hard active teas, and also stretchability that does not interfere with their movement. And it can be handled without any problems with climate change without windshells or rainshells. These are extremely reliable multifunctional insulation that add a new side to the existing active insulation. Of course, it has a wide range of functionality, but not all roles are perfectly suited. Depending on the journey, you may need to prepare the perfect equipment that matches the route, but there is no doubt that it can be conveniently used from autumn to winter to spring, if you have a route of a certain level of difficulty and length!
includes a "unpadded windshell breather light jacket" and a " with more than double the amount of padding " If you choose a jacket that suits your purpose and activities, you will be able to relieve the stress of choosing clothes this winter and enjoy it even more comfortably.
