If you’re looking to add a little extra fun to your next adventure, the Women’s Altitude ‘Mongrel’ is for you! Don’t let the name fool you, this is one seriously good thermal Base Layer. The perfect combination of performance, warmth and comfort with a little bit of fun thrown in for good measure.  

Get in quick, all Mongrels are strictly limited edition and once they're gone, they're gone for good.

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. 

Ultra Trail Australia mandatory gear approved thermals

Designed to be worn as a body tight ‘contact fit’ layer. Slightly looser than the Altitude long sleeve styles.

Drop back hem and extra length in body. 

Thumb loops.

Comfortable and colourful

I bought both Mongrel short sleeve and long sleeve. So far I’ve only had a chance to wear the long-sleeve and I love it. I like that there’s a bit more room in the sleeves so they’re not skin tight, and I didn’t realise there’s a thumb hole which I love (good length for colder days). I would have liked a bit more fabric in the boob area, but otherwise the general fit is good. The mix of colours and stripes is a delight.

Amazing top

I’m so happy with this top! Thankyou io! The fabric is wonderfully soft and the colours are such fun - I have black and grey base layers and feel much brighter and happier in this! The size chart is spot on. Since receiving this I’ve ordered more from io, really like their philosophy and products are amazing.
Traveling to Alaska in May, and the UK next year. I’m carefully building a small travel wardrobe (which I’ve already started to wear ALL the time - these clothes are so so comfy!) I am even more thankful to have found a local company to support.

Warm and funky

My order was processed and arrived quickly. I love that the Mongrel has some colour to add to the generally drab range available for winter. I love that it doesn’t make my skin prickle and itch. Highly recommended.

Mongrel

This thermal is so soft, no wool ‘itch’ I find it incredibly warm and comfortable, long enough in the body to tuck into pants. Customer service was amazing
Highly recommend this company
