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 choosing another style.

The Women’s Altitude Zip Base Layer thermal takes natural temperature regulation to a whole new level. It is the perfect ‘go to’ thermal layer for just about any adventure, especially if you’re expecting to hit a range of temperatures. Zip down when it’s mild, zip up and thumb loops on when the temperature drops.  The high collar also offers an extra level of warmth beyond the Women's Altitude Crew Neck Base Layer version of this top.

Flatlock stitching, raglan sleeves and tag free to eliminate chafe and maximize 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 Base Layer Thermal top is the perfect combination of performance, warmth and comfort.  

(For a more relaxed fit try our Ultra Zip.)

Ultra Trail Australia mandatory gear approved thermals.

Originally designed to be worn as a base layer, (is usually underneath something else), this is a ‘contact fit’ layer so will hug your body. If you don’t want it to fit, feel or look like a second skin, you might try another style, or go up a size, but please note: even going up a size will fit quite close to your body because of the fabric and cut. 

Drop back hem and extra length in body.

Hi again Graham,

As discussed, quite happy to pass on a post paid label to get that one back to us.

If you do, we can get the correct sized one sent out to the UK for you.

All the best,
Coby

Such great quality

This top is just as pictured. It is so flattering! The material is extremely soft and it's nice enough to wear as a top without covering it up under your other layers.

LOVE IT
