Some people completely overlook underwear as the foundation of layering. Big mistake. If you haven't already tried our Women's Zodiac Merino Wool Underwear, you're well and truly missing out. Rest assured, they're every bit as soft, lightweight, warm and comfortable as the rest of our high performance thermal layers.

Enjoy the hipster fit, full coverage brief that stays put, never gathering or moving, ensuring a comfortable fit all day long. Tag free labels, flat lock stitching and a flexible and ultra-soft ioMerino elasticated waist band help eliminate chafe and maximize comfort.

They're naturally temperature regulating, breathable and moisture wicking for year round comfort. Perfect for all of your travelling, running, hiking, skiing, snowboarding, climbing, cycling adventures, and whatever else it is you get up to in the outdoors!

Made with 170gsm lightweight 96% superfine Australian Merino and 4% Elastane MicroMerino? - for an easy four-way stretch and freedom of movement.

They stayed up.....

These briefs were terrific. They stayed in place all day and didn't slip down and become uncomfortable while climbing or hiking. They also dried pretty well, and are ok to wear slightly damp. A winner for me.

Love the comfy fit of these briefs. I'd been a fan of the Full Briefs but thought I'd try these. Elastic is wide and comfy even on sweaty days. And merino is terrific. Thanks iO.

Fit perfectly and very comfortable and soft material. I like the wider than other brands' gusset. I thought I'd find the elastic waistband irritating but it's quite comfortable. I'd get these again for everyday and travel.

I love these knickers for travelling

Whenever I go away, I am trying to pack light and smart. ioMerino knickers are part of that - I can travel for weeks with 3 pairs of knickers that are comfy, that wash out really well and dry super fast.

Thanks Tory :) Nothing beats natural superfine merino where you need it most!
