Our Altitude range was originally designed as a baselayer, to fit close to your body for maximum performance, so it’s snug but soft, with plenty of give for extra comfort. If you’re usually a medium, for example, you might find the medium fits tighter than you’d expect because it’s designed to be ‘contact fit’ and look and feel like a second skin. If you’re looking for a more relaxed fit you might consider sizing up (it will still be relatively snug) or .

The Men's Altitude Crew Neck Base Layer is the ‘go to’ thermal layer for just about any adventure and our all-time best seller. It’s the perfect thermal layer for core warmth when you’re layering up, yet versatile enough to be worn on its own in milder conditions.

Tag-free, flatlock stitching and raglan sleeves help eliminate chafe and maximise comfort. The drop back hem and extra body length is designed for tucking into your outer layers. Thumb loops keep your hands warm and stop your sleeves riding up when layering.

This top is the perfect combination of performance, warmth and comfort.

(For a more relaxed fit try our or tops.)
