Made from our supersoft bamboo cotton blend with elastane for comfort and stretch. This base layer has a slim fit with a mock neck.  The sleeves reach to the mid hand with horizontal thumb holes to keep you warmer on cold starts. This heavier weight fabric keeps you warm but is also highly absorbent to help you regulate your temperature on longer outings

Classic Jersey


68% Bamboo Viscose, 28% Organic Cotton, 4% Elastane.

Supremely soft, smooth and comfortable. Imagine cotton T-shirt fabric only softer and smoother with a little stretch. As it's bamboo it's incredibly absorbent so it stays dry helping with temperature control - you stay cool in the heat, warm in the winter. There’s nothing better for next-to-skin comfort.
