Men's Base Layers

Discover Our Men's Base Layers


Our men's base layers sit against the skin as the next-to-skin layer that carries perspiration away and holds warmth where you need it. We build every piece of thermal underwear in this collection for long days outside, in weather that shifts between effort, rest and cold.

Anti-Odour and Antimicrobial Base Layer Tops


Most tops in this collection use an anti-odour base layer fabric, and several add an antimicrobial finish on top of it. That pairing lets you stay fresh through repeated wear on a multi-day traverse or a weekend at camp, so one top covers several days without a wash.

Breathable, Moisture-Wicking Base Layers


A breathable base layer knit paired with moisture-wicking fibres pulls sweat off the skin and pushes it toward the outer layers, which keeps you dry when your output spikes on a climb. Sweat management depends on contact, so pick a size that follows your body without compressing it.

Québec-Designed Base Layers Built for Layering


Some styles here are a Québec-designed base layer, and one is manufactured in Québec. Each one works as the first layer in the layering system, so it pairs with a mid-layer for insulation and a shell for wind and rain.


Why Choose Chlorophylle for Men's Base Layers?


We design and test our gear in the conditions it's meant for, and that's what separates this collection from a generic Québec base layer brand offer.


Québec Outdoor Expertise


We're a Québec outdoor brand rooted in Saguenay-Lac-Saint-Jean, and we build outdoor apparel for what a Canadian winter actually delivers: wet snow, wind, and long temperature swings between effort and rest.

Performance Fabrics That Regulate Temperature


Our thermoregulating and wicking fabrics handle temperature regulation as your pace changes, and a water resistant option adds protection when snow melts against the fabric. Because those same knits keep you warm and dry under a shell, they carry over directly to our men's cross-country ski clothing when the tempo climbs. Lightweight and recycled options round out the range for milder days.

Sizes and Styles for Every Adventure


Base layer sizes run from S to XXL across the collection, in black, blue and green. Wear one under our men's hiking apparel as a hiking base layer on a summer summit push, or under an insulated shell for snowshoeing in February, and the fit stays close and quiet.
