Introduction
All-weather Pants for autumn and winter
The AW Hike Pants are a simplified version of our Winter Hike Pants.
By removing the crampon guards and shoe hooks, we created an all-weather soft-shell pant designed for comfort — from everyday life in autumn and winter to snowy mountain trails.
Developed in collaboration with Pertex using their Shield Air waterproof and breathable fabric technology, the material combines weather protection with excellent ventilation and stretch. The smooth jersey lining is so comfortable you could even wear them inside your sleeping bag.
And of course, they feature Yamatomichi’s signature 5-Pocket System.
2025 update

Form and function
Comfortable in a blizzard
With stretch and softness you wouldn’t expect from a waterproof, breathable fabric, the AW Hike Pants are so comfortable you could even sleep in them. Their simple, versatile design blends easily into everyday life, taking you seamlessly from home to the snowy mountains.
You might doubt that pants this refined could withstand a snowstorm — yet the Pertex Shield Air soft-shell fabric blocks out 99% of the wind.
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
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.
Pair with tights in colder seasons
For midwinter or snowy mountain conditions, we recommend combining them with Light Alpha Tights or wool tights. Thanks to their excellent stretch, the AW Hike Pants layer comfortably over tights without feeling bulky or restricting movement.
Elastic cords for snow
To Prevent the hems from riding up when hiking in snow, we’ve Added designated loops for elastic cords.
*elastic cords not included.
Details
Polartec Microfleece Lining for Inside the Side Pockets for extra warmth.
Half gathered cuff for a sleek silhouette.
Waterproof Zippers further Improve wind resistance.
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.
