Built for the in-between.

When the weather cannot make up its mind, the Shoulder Season Base Layer Top steps in. Made from the same lightweight, ultra breathable mesh fabric as our Egg Cradle Boxer Briefs, it delivers warmth without overheating and dries almost as fast as you can work up a sweat.

A slim fit makes it easy to slide under a shell or mid layer, while the soft, stretchy fabric moves naturally with your body. Breathable and moisture wicking, it keeps you comfortable through cool morning runs, brisk hikes, and unpredictable travel days.

It pairs perfectly with the Shoulder Season Base Layer Bottoms for a complete system built for unpredictable shoulder season conditions. Quick drying, breathable, and versatile, this is the layer you will reach for when the forecast says “maybe.”
