Our Altitude range is designed to fit close to your body for maximum performance, so it’s tight but still soft, with plenty of give for extra comfort. Not only does the Women's Altitude Base Layer Tee look and feel good, it's also incredibly versatile, taking you through a wide range of temperatures and conditions. Wear this Base Layer T-shirt as part of our layer system for extra warmth, and when the temperature rises, you’ve got the perfect lightweight and breathable T-shirt that delivers the comfort and performance you need to go the distance. You can always size up if you want a little more room, but it’s definitely designed to fit close to your body.

(For a more relaxed fit try our Ultra or Universal T-shirts.)

Tag free, flatlock stitching, raglan sleeves eliminate chafe and maximize comfort.

Why you’d buy this: You like your stuff to fit nice and close to your body whether you wear it on its own, or under another layer and don’t want any extra bulk or bunching. You might also want a bit of extra length which this one gives you. It’s super soft and comfy, and 96% merino so it’s super natural which means almost no microplastic issues when you wash it or landfill when you’ve finished with it.

As with all our clothes, the merino delivers natural temperature regulation, breathability, moisture wicking and odour resistance.

Love it! Will buy more.

I have always bought Universal Tees and I wear them daily in summer. I bought the Altitude Tee - Southern Cross as underwear that could be outerwear if I needed it to be.
The shorter sleeves, close fit and slightly lower neckline were perfect when I wore it under a long sleeved top recently. I'll buy more of these "double duty" t-shirt/underwear Altitudes. Love the Southern Cross on the shoulder too and would purchase the Southern Cross version in different colours if available (navy, red or mint green would be good!).

Hey Natalie! Thank you so much for your review of the Southern Cross Altitude Tee. We can do this design on any of the Altitude Tees. Just contact Coby at hello@io-merino.com and he'll be able to sort it for you :)

Liked it so much I bought a 2nd

Bought it in green. It’s extremely soft. Washing was easy. So I bought it in purple. Love them both.

Great quality

Great quality product. Would probably go up a size next time. I was within the sizing range but it is quite tight on me. Still ok to run in but prefer a bit less fitted.
Otherwise very happy

I give this top marks

Bought this for my daughter who DOES run ALL trails - champion trail runner, represented Australia twice in overseas trail championships (worldwide), she epitomises the trail runner, happy, caring, loving nature. Ideal present for her, I think.
