High-Performance Perforated Base Layer Leggings

Designed to eliminate all cold, our Zelios men's heavyweight (278g) base layer pants are designed to deliver performance in the harshest of winter conditions.

Named after the Greek god of power, these breathable moisture-wicking and odour-resistant leggings are made from pure merino sourced from Lanerossi (Estd. 1817).

Tested on long muti-day treks in the Himalayas, and designed for extremely long durations of wear, our leggings have a perforated rear band to aid ventilation and will deliver outstanding thermo-regulation to keep you warm, and unlike synthetic alternatives, your skin dry. Our base layer bottoms are a firm addition for all outdoor enthusiasts.

Consider These Pieces

Merino Wool Yarn

Exceptionally fine and naturally intelligent, merino wool is prized for its ability to regulate temperature while remaining soft against the skin. Designed by nature to adapt, it provides warmth in cooler conditions and breathability when temperatures rise.

We source our chunky merino from Peru and our extrafine and superfine merino is supplied by industry favourites Zegna Baruffa (Est. 1850), Papi Fabio (Est. 1890) and Lanerossi (Est. 1817).

Benefits of Merino Wool

Moisture-wicking fibres keep you fresh, dry, and comfortable.

Light yet warm, with natural strength and shape retention.

Ultra-fine fibres feel exceptionally soft against sensitive skin.

Requires less washing and resists creasing.

Renewable, biodegradable natural fibre.
