Don't ruin great layers with average undies. Our best-selling lightweight Altitude Merino Underwear offer superior performance to keep you warm and comfortable when you need it the most. 

Tag-free labels, flatlock stitching and a flexible, ultra-soft ioMerino elasticated waistband help eliminate chafe and bulk and maximize comfort and a self-fabric fly adds both comfort and function. Say goodbye to ordinary undies, and hello to the Men's Altitude Active Merino Boxers.

Self fabric real fly. Mid rise. 

Designed to fit perfectly under our other layers, they are leaner, firmer, active style, with less fabric in the legs and crotch.

Happy To Pay More If They Last

Seem good. The extra length is a good point of difference. Fit a little larger than expected. I'm usually a Large in merino boxers and I think a Medium might have been better for these. Also a little thinner than expected, so will see how the durability goes. Hopefully better than too many pairs of Mcpac.

I will never wear any other type of underwear again

I tried a couple of pairs of io trunks and boxers, and both styles were exceptionally comfortable, leaving any cotton or synthetic underpants for dead. I have now bought enough to not have to wear anything else.

They fit well - not to loose and not too tight

Also great for wearing under my wetsuit for extra warmth. Now, if IOMerino ever makes a vintage style wool bathing suit, I'll be set for any adventure.

Down Under

What can I say about these 'down-under'? They are comfortable, warm, soft, breathable - just what one needs next to one's 'down-unders'!
