Great Merino Underwear

These are very comfortable underwear, moisture wicking is excellent, and able to be worn multiple times.

Stretches Out And Rides Up

I like that these are wool. The fit is alright at first, but it stretches out as the day goes on. The ride up on the back side, too. I would not recommend these.

Well Made But Runs Small

I really wish I order a size up in these. The stitching and fabric are great but a little tight. I expected them to stretch out a little after wearing them for a while but they did not.

I Prefer The Boxer Briefs

They do not provide enough support. They lack fabric where it is needed. Was worth a try. Tighty whities would probably be better in terms of fit.

I’m 5’11”, 165 lbs and ordered medium and I think small would fit me a little better. Cool and lightweight. No itch from the merino wool.

Looks Good But It's Flimsy

Used when traveling in warm climates, washing every day, it is better than cotton but flimsy and the fabric is already transparent in between legs. Also very expensive.

Best Underwear Ever!

I wear my merino briefs and previously purchased boxers daily. They are comfortable and never pick up any odor. I have thrown away my cotton underwear!

I Don't Know How They Always Seem To Stay Fresh

My fave underwear. A little bit low profile on the sides, but that's also great for it staying cool and ventilated. Can get away with more then one wear on really long trips, which is probably their best features.

Great Productr

I use this underneath my compression shorts. They are very breathable.

The Only Underwear I Ever Buy

I've been purchasing IB for 10 years and these are the only briefs I wear. I still love the design and fit!

Great For Travel

Super comfortable and fast-drying. I like packing light, and with these I can pack just a few pair while traveling, wash in a sink, hang to dry and in a few hours they're as good as new.

Not My First Purchase

I enjoy the fit and comfort of these undies. Plus they never smell ... thanks.

Poor Design, Not Enough Material

Not sure who designed these but pretty sure it wasn't male. The width of the crotch area is far too narrow. This causes the male parts of my body to slip out, usually on one side or the other. Very uncomfortable. When I measured the width, it was about 2 inches. When I measure the crotch width of other brands of briefs I own, it's 4 inches. I noticed at least one other one star review where the person had the same issue I do. I certainly can't recommend this product, although I own and like a lot of other icebreaker clothing.

Perfect In One Size Above Chart/recommendation

No fly to separate; Merino blend prevents the moisture buildup of cotton briefs. Size chart shows I am XL, but they are tight; XXL fits me perfectly.

The Only Underwear I Have And Will Ever Have

Ever since I switched to these briefs they have changed my life. As someone who sweats a lot, these are breathable and quick dry and super comfortable. Compared to cotton briefs these are a game changer!
