Base Layers

Pure merino base layers for everyday warmth, outdoor performance and the season in between.

Base Layers is BCA's curated range of merino wool thermal clothing: fine-gauge merino tops, vests, singlets and long johns selected for their warmth, softness and all-day wearability. Merino's natural properties make it the preferred base layer fabric for outdoor activity and cold-weather commuting: it regulates body temperature across a wide range, wicks moisture away from the skin, resists odour through natural antimicrobial properties and stays soft against the skin across repeated wears. The BCA range focuses on pure merino and superfine merino constructions that perform as well in a day pack as they do in a weekly commute wardrobe.

Women's options cover the full thermal base layer spectrum: the ALASKA long-sleeve thermal top and LUNA pure merino long-sleeve provide warmth without bulk, while the DUSK merino vest adds a lightweight layering piece for core warmth without sleeve restriction. The HEIDI lightweight merino camisole with lace and BAROSSA smooth camisole extend the range into finer-weight everyday wear. Men's options include the FORT merino short-sleeve tee, the LUCAS thermal long-sleeve, the KNIGHT thermal long john for full-leg coverage and the GETAWAY tank singlet for active use.

Hikers, skiers, trail runners and outdoor enthusiasts who need a base layer that performs across a full day of varied activity reach for merino as the first choice for temperature regulation and odour control. Commuters and office workers in cooler climates use merino base layers as their everyday thermal underlayer under business and casual wear. Travellers reach for them as a compact, versatile wardrobe layer that refreshes quickly and packs small.
