The Altitude range is designed to be a tight, but comfortable, fit. If you size up it will give you a little extra room, but it will still hug your body as that’s what this range is designed to do. If you want a looser fit consider the Ultra or Universal range.

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.
The Men’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 Men'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.

It feels so soft and comfortable! Look forward to buying more merino.
Perfect for when riding my bike. Long sleeves are great for keeping the sun at bay. I find it breathes well and wicks very nicely. Highly recommended.
Have been a long time user of merino products from ioMerino right from the early days and I am so glad to see them hanging in there and providing updated fantastic clothing. I use the base and mid layers all year round for golf, walking and exercise. Wish I could buy more. I still have ioMerino shirts from over ten years ago - amazing stamina!
I find myself virtually living in it full time.
It's the best base layer I have, I've got several kinds but it's my favorite, I've bought two of them 10 years ago in Quebec. Unable to find any more, I made the purchase in Australia and I am still satisfied with the 2022 version.
Great product works well for sea kayaking
