Women's Size Chart - Altitude 'Contact Fit'
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.

Women's Size Chart - Universal, Ultra, and Horizon 'regular fit'
These garments are designed true to size, but going up a size in the Ultra will give it a slightly looser fit, whilst remaining sporty. The Universal and Horizon are already designed as a more casual fit.

DETAILS
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. 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 Ultra or Universal tops.)
Ultra Trail Australia mandatory gear approved thermals.

T
Todd (Adelaide, AU) Great all rounder
Nice, light and snug fitting, perfect as a base layer or to throw on over the top to keep you warm. Looks great, fits great, 100% happy with my purchase and already looking to add more merino to my running kit
B
Bronwyn Steer (Railton, AU) Warm & comfortable
Very warm & comfortable, happily purchase again
A
Adam Kavanagh (Throsby, AU) Another great piece of kit
It has been a while since i brought any IO and putting this on reminded me it has been too long. Putting this on is like a nice warm hug - i know that sounds ridiculous. The thumb loops work really well with the Newton Gloves. I wish i had gotten them at the start of the Canberra winter as opposed to the end.
J
John Cantor (Adelaide, AU) Merino Base Layer.
I use Altitude as a light weight base layer for cycling. It keeps me warm, but not hot even if i get it all sweaty. Initially I thought the the “glove” extension of the sleeve was a bit odd, but now in the cold weather I find it useful in keeping my hands warm. They fit easily under my cycling gloves, leaving no gaps.
D
Douglas Hopkins (Melbourne, AU) Get warm this winter
Two new tops are providing me with continuous comfort and warmth while l work from home. No itchiness whatsoever. Multi wear between washing. The tops are a very solid base from which to start your clothing layering.
R
Richo (Adelaide, AU) First purchase
I purchased an Ultra Zip, an Altitude long sleeve crew and a skull cap. I am generally between Medium & Large. In these styles for me at least - Medium is plenty big enough. The Ultra Zip fancy enough to wear to the pub or out to tea, the Altitude tee does the job exactly as described. The skull cap is brilliant. Small, warm, thin - definitely an essential piece if kit for Autumn/Winter in Adelaide.
Short version is - more than happy - hoping for a good long life and will look to buy more. The Ultra fabric smoother - the Altitude "feels" tougher. Might go for Altitude when looking for warmth and robustness - Ultra when looking for style & comfort.
A solid 4 1/2 out of 5 stars and I am told I am not easy to please!!!!!
Cheers
Richo (Adelaide AU)
What layer is right for you?
Got questions about what item will fit you best or which fabric is most suitable for your adventures? We’ve developed a quick guide to help make choosing the perfect layer easy.
“ I can honestly say your products are at least 25% better than (that other brand). And I’m a Kiwi. Not to mentioned feeling better about Fiji production and the fact that your cuts fit me better. The weaves are also finer and feel softer. Good on you and please share this with your team. I love supporting you! Heaps good.”
