SIZE & FIT

True to size - but if you’re a fan of our existing Altitude boxers you may want to size up.

Model wears size small in black and chilli pepper. Model specs - height 173, chest 99cm, waist 76cm.

Model wears size medium in dazzling blue and navy. Model specs - height 181cm, chest 103cm, waist 81cm (32 inch).

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

Size Guide.

If you’re not a boxer guy, or a brief guy, these trunks sit quite nicely in the middle thanks very much. Made from our ultra comfy Merino+ fabric, (it’s the same epic fabric we use in our Ultra range of tops!), they deliver all the comfort and performance you’ve come to expect from our premium merino fabrics, but in a more streamlined fit. They're a bit more snug than our Altitude Boxers, with a little more coverage than our briefs, They fit true to size, but if you’re coming across from our Altitude Boxers you may want to size up.

Tag-free labels, flatlock stitching and a flexible, ultra-soft ioMerino elasticated waistband help eliminate chafe and bulk and maximize comfort. Say goodbye to ordinary undies, and go with Men's Ultra Merino Trunks.

Merino wool is best fabric

Need to develop larger sizes 3xl

Hi there Jim,

Thanks so much for your review!

We've been trialling 3XLs in selected products (See here - https://iomerino.com/products/universal-polo?variant=40392944123962 ) so hopefully we'll get some in the Ultra Trunks.

All the best,
Coby

not the right fit

I chose these over the Altitude style because of the blend - thought the 12% nylon would make for a longer lasting material. However, the fit is not right for me; they fit too low on the hips.
I've a 34inch waist and bought a Large.

Great undies

ioMerino trunks and boxers are just the best. People think that wool undies would be so uncomfortable, but nothing could be further from the truth. Silky smooth fine wool, not in the least pickly, stink resistant, so comfy. If marooned in the jungle for a week, these are the undies I would want to be wearing. And ioMerino is so helpful/cooperative if you find you have messed up your order. Highly recommend.

Very comfortable

My favourite underwear after trying a lot of brands and styles (I have tried the ioMerino Briefs but not the Boxers, if that helps). Very comfortable, the right support for me, and I like the vibrant colours too.
Note I wear size 32 pants and Medium shirts but I found size XL was the best fit for my body and preference. I suggest buying one at a time until you are happy with the fit (and then buying a bundle or two!).

Unfortunately too "ultra"

I normally wear a size M. I wear the boxer shorts from iO (size M) often and very happily. I should probably have chosen a size larger for this model. The quality is top but in my case unfortunately not stretchy enough and therefore too uncomfortable for everyday wear.

Very comfy, fits well. Prompt delivery. I’m a total merino guy.

Live the long sleeve length and the weight of the shirt. Haven't worn in summer yet, but I think it will be good for hot weather as it is loose fit. Super comfortable and you don't need to wash very frequently.

Super comfortable and warm socks

Very comfortable, and love that it doesn't need washing very much.

Even amazing in the rain

I have to say i love my pinnacle, I wear it while riding as its warm and light but doesn't over heat like synthetics might. What i didn't realise is how amazing it is in the rain - I got caught riding in a real down pour, normally this means i'm cold and heavy as well but not now. I was wet, sure. but the wool kept me warm and I was able to finish without discomfort. Awesome - Thanks IO

Great product

Great product, why don't you sell a long sleeved version?
