Overview
Blocks snow and wind, releases moisture buildup.

Built for winter activity, this L4 Mid Shell® pant blocks snow and cold wind while letting built-up moisture escape as you move. Everbreath® Air, a membrane engineered specifically for Mid Shell® use, pairs with generous stretch to balance windproofing, breathability, and mobility through the coldest months. It's designed to work as the inner half of finetrack's Double Shell® system, combined with L5 Outer Shell pants. For the Fall 2026 renewal, we've further refined the fit for that pairing, making the piece lighter and more comfortable to wear.

An inner layer, or worn alone

Built primarily as an inner layer to boost the warmth and windproofing of your outer shell pants. No buttons or buckles at the waist, no zippers on the hand pockets, just a simple design made to layer easily. At camp or in a hut, shed the outer layer and wear it on its own. With solid water resistance and windproofing, it can also stand alone in milder conditions or high winds. Supple stretch, thin, and light, it performs well whether layered or worn solo.

Move freely, wear it all day

Winter demands you block the weather from outside while letting the moisture building up inside escape. Flow Wrap® Pants deliver both, windproofing and true breathability in one layer, cutting moisture and condensation buildup even in the harshest conditions.

Breathability that holds up: Everbreath® Air

The membrane at the core of this piece, Everbreath® Air, is purpose-built for Mid Shell® use. It blocks cold wind while letting trapped moisture escape, keeping overheating in check. Water repellency on both the face fabric and the liner knit prevents the water film that saturated fabric would otherwise trap, protecting breathability over the long haul. That performance holds up through long days and full winter layering, moving moisture out instead of trapping it.

※Breathability: 10,000g/m²/24h (JIS L 1099 A-1) / 20,000g/m²/24h (JIS L 1099 B-1).

Stands up to snow and light rain

Durable water repellency on the face fabric sheds snow and drizzle, so weather changes don't slow you down. A 10,000mm water pressure rating holds the line against the elements without sacrificing breathability.

※Water pressure resistance: 10,000mm (JIS L 1092 B).
※Not seam-sealed. Not intended as fully waterproof.

Stretch that moves with you

220% crosswise, 143% lengthwise stretch keeps you unrestricted even layered up: bending, lifting your legs, all the big moves winter activities demand. No stress on the fabric, no stress on you. The knit construction feels supple against the skin, built for hours of continuous wear.

※Per JIS L 1096 B-1.

Engineered for Double Shell® layering

Flow Wrap® Pants are the L4 Mid Shell® half of finetrack's Double Shell® system, combined with L5 Outer Shell pants. The Outer Shell fends off snow and wind from outside, while Flow Wrap® Pants underneath let moisture escape and protect against condensation. Together, the two layers provide more protection with less buildup, holding comfort steady even through harsh conditions.

Vent on demand with LINKVENT®

Feeling the heat mid-climb? Open the side vents and let it out, no need to strip layers to cool down. Layer it with a finetrack Outer Shell and the vent positions align through our LINKVENT® system, so you can adjust airflow without ever removing the Outer Shell.

Built for winter layering

A simple pull-on waist with a drawcord cuts bulk, so the pant layers cleanly under a shell. Left and right hand pockets skip zippers to keep things simple. Durable water-repellent fabric reinforces the hems, standing up to the snow and moisture your feet see most.
