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.

S
Susannah Excellent singlet, but runs small
Excellent sports singlet. I loved it so much I went back and bought it in several colours.
However, it runs quite small. I normally wear a M or L in womens clothes, and I had to get the XL in this singlet.
Once I sorted out the sizing I was really happy with it.
J
Jennifer Andrew Lovely
Lovely fit. Soft fabric. Smooth flatlock seams. And it's even (just) long enough for my extremely long torso. I'm 184cm tall, and all torso :).
R
Robin Bode (Brisbane, AU) Racerback singlet
Love love LOVE! I wear it throughout the year - cool in summer and great for layering in winter. Beautiful fit, not scratchy. Very comfortable…and they don’t fade!
P
Penny S. (Perth, AU) Very comfortable
Bought for an extra warmth layer and emergency swimming top when backpacking. Very nice and comfortable.
E
Emilie (Sydney, AU) Essential
Must have for the wardrobe!Perfect for layering and looks great on it’s own. Very versatile with all the merino plusses. All round winner
H
Heather Griffiths (Melbourne, AU) Great colour options
I was worried this might be a little short for my extra long body, but am really happy with its length and that it doesn’t ride up. Nice and snug and beautiful colours to choose from.
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.”
