Introduction
From your front door to the peak
For snowy winter hikes, we wanted to make a pair of pants you can wear from the moment you leave your front door, all the way up to the top of a snowy ridge. They are so comfortable, you can keep them on while you sleep in your tent!
The Winter Hike Pants are made of exceptionally waterproof, windproof, soft, and breathable Polartec Power Shield Pro, equally as comfortable and flexible as most softshell pants, and equipped with our iconic 5-pocket system.
2025 Model Update
We’ve upgraded to a new waterproof and breathable soft-shell fabric featuring Shield Air technology—co-developed by Pertex and Yamatomichi—built to handle tough conditions while keeping you comfortable on the move.

Product story
For snowy mountain hikes
Illustration: Jerry Ukai
In winter, the weather changes more drastically than in summer. An abrupt change in the weather may turn your peaceful walk into a severe struggle. After a gust of wind, a snowstorm may suddenly wipe out everything in front of you. It is difficult to predict the time needed for a day’s hike because after a blizzard, all traces may disappear and you may have to trudge through a completely new fresh snow landscape.
Is it all bad?
Of course not! On a bright sunny day, I am blown away by breathtakingly beautiful mountain landscapes. At night, I eat a slowly simmering hot-pot together with my friends in our shared tent. The air is crisply cold, but I lie down in my warm sleeping bag, thinking about the beautiful mountain ridge I will be walking tomorrow. All of these are precious moments that can only be experienced in winter.
I love the winter mountains so much that I decided to create a pair of ideal pants for snow hikers. One concern was that many existing winter hiking pants came with really poor pockets. In many cases, the pockets are either too few or too difficult to reach. To make up for this, our Winter Hike Pants are equipped with our unique 5-Pocket system.
We also added metal hooks at the end of the hems to securely catch your shoelaces so that the hems will not crawl up, and consequently, the pants can keep out snow even without gaiters. The inner side of the hems is reinforced with a tear-proof material to protect against the spikes of crampons. And because of the flexibility and excellent breathability, our Winter Hike Pants are so versatile that you can wear them from the moment you leave home without the need to change along the way.
Polartec’s high-performance softshell, Power Shield Pro is waterproof, highly breathable, soft, and stretchable, yet the texture is like a normal kind of fabric. Usually, breathable materials like fleece lets in air, so it can be cold when it’s windy or when you are resting. But what’s special about the Power Shield Pro is that it gets more breathable when you start moving but feels almost windproof when you are standing still. In short, it is warm when you are resting, but breathes well when you are on the move. The material shuts out 99% of the wind, while letting through the remaining 1%. Its superior waterproof performance protects you from getting wet and assures your comfort even when you hike in heavy snow, or when you have to keep walking during a blizzard on an untraced trail.

Form and function
Ultra comfort
The Winter Hike Pants are exceptionally breathable and as comfortable as softshell pants, although they have less water pressure resistance than general waterproof fabrics.
From the moment you leave home, while up on a cold mountain ridge, and even while sleeping in your tent at camp, the Winter Hike pants will keep you comfortable.
Pockets for smartphone and maps
Yamatomichi 5-Pocket design can neatly store your map, snack, wallet, and other items you need during hiking, without interfering with your leg movement.
Each pocket is zippered to keep snow out, and the smartphone pocket on the right has been enlarged to fit a smartphone with a waterproof case. The side pockets are lined with Polartec Micro fleece to keep your hands warm.
1st & 4th Pocket
The pockets are zippered to keep snow out. They are also lined with Polartec Micro fleece to keep your hands warm.
2nd Pocket
The 2nd pocket is perfect for your smartphone. The perfectly-allocated pocket just behind the hipbone secures a smooth leg lift, preventing your phone from bouncing around and safe and intact when sitting.
3rd Pocket
The 3rd pocket is positioned high for wallets, etc. The long zipper tab allows for easy opening/closure of the pocket.
Key loop
We made a key loop inside the right front pocket to keep your keys etc. safe.
5th Pocket
The 5th Pocket is made to fit the size for the normal hiking map. It is also convenient for putting trash during hiking or keeping snacks close at hand.
Shoelace catcher and crampon shield
Gaiters can keep out snow and protect against the sharp spikes of crampons. They are, however, troublesome to attach/detach when you take off your shoes, and gaiters can restrict the movement of your ankles. For these reasons, we prefer to hike without them.
Our Winter Hike Pants come with metal hooks at the end of the hems to securely catch the shoelaces of your boots, preventing the hems from crawling up to keep out the snow. The hem is adjustable with a drawstring to tightly cover the upper part of the boot.
The hem is reinforced with 500D Cordura fabric to protect the pants from the sharp spikes of crampons.
The shoelace catchers may be unhooked when you have to keep trudging through the deep snow.
The metal hooks at the end of the hems securely catch the shoelaces of your boots, preventing the hems from crawling up to keep out the snow.
Shoelace hooks can be tugged away when not in use.
The hem is adjustable with a drawstring to tightly cover the upper part of the boot.
The hem is reinforced with 500D Cordura fabric to protect the pants from the sharp spikes of crampons.
To keep the pants in place, pass the drawstring around your boots to secure.
Details
The side pockets are lined with Polartec Micro fleece to keep your hands warm.
The pockets are zippered to keep out snow and a puller is attached for easy access even with gloves on.

Material
Pertex Shield Air
A soft-shell fabric co-developed with Pertex using their Shield Air technology — waterproof, breathable, and truly air-permeable.
Developed to improve water resistance, long-term durability, and production consistency over existing nanofiber membranes, Pertex Shield Air uses a unique porous polyurethane structure that repels water while allowing air to pass through. Unlike conventional waterproof-breathable materials that rely solely on moisture permeability, this air-permeable construction delivers an exceptional sense of ventilation and comfort.
With a water resistance of over 10,000 mm — on par with our UL All-weather series — the fabric offers ample protection for winter and alpine conditions. While the AW Hike Pants are not fully waterproof due to the absence of seam sealing, their performance is more than sufficient for winter use.
The Pertex Shield Air soft-shell fabric, developed specifically for the AW Hike Pants and Winter Hike Pants, combines a stretch nylon outer (86% Nylon, 14% Polyurethane) that sheds snow easily with a smooth, lightweight jersey lining for comfort against the skin. The result is a softness and ease of wear you wouldn’t expect from a waterproof material.
The above data reflects our in-house test results (measured values only and not guaranteed).
