Size + Fit
The Ultralight Shirt has a regular fit.
The Ultralight Shirt is part of a system of ultralight, highly technical all-weather clothing designed to take you across every climate, environment and terrain on the surface of Earth. This is the shirt you pack when it’s the only shirt you pack.
It’s made with an advanced material built by Schoeller using a stretchy core-spun polyamide – an elastane core wrapped in a high-tenacity sheath – that keeps you cool when you need it to, retains its shape, repels water and resists creasing.
The shirt is pared back but packed with smart features. It has laser-cut ventilation, a hidden zip-entry chest pocket, invisible snap closures and superstrength French seam construction throughout.
The Ultralight Shirt is built from an advanced material, precision engineered to shrug off high heat and humidity. It’s 93% polyamide and 7% elastane. But the material isn’t just polyamide with a bit of stretch thrown in. It’s a core-spun construction, which means there’s an elastane filament running through the centre of every yarn, wrapped in a sheath of high-tenacity polyamide. The elastane core gives the material its extreme stretch and snap-backability. The sheath gives it durability and abrasion resistance but with a surface that feels like a shirt rather than yoga pants.
Instead of buttons, the front of the shirt fastens with 7 invisible snap closures from RIRI, one of the world’s most respected zip and fastener manufacturers. Each 11mm snap is hidden behind a covered placket with a sharp angled seam. From the outside, there’s just a clean, unbroken line running the entire length of the shirt. The snaps are fast to open and close, virtually silent and far more reliable than buttons. They won’t pop open, snag on branches, or slip through wet fingers.
