Perfect for the backcountry!
These are my now go to for all backcountry adventures. They are comfortable, breathe well, and they don't smell after days of backpacking. I have two pairs and looking to get a few more, something I would pay full price for without expertvoice.

Outerwear?
I wore these as outerwear on a group ride and got compliments the whole time, extra breathable, almost too much coverage!

They have a really nice fit and are very comfortable. Seems to have high quality stitching.

Great product, obnoxious tags
The products are comfortable and functional. I have a lot of Icebreaker gear. I would suggest losing the oversized and uncomfortably placed tags. I’ve removed many of them, but they are sewn into the seams rather than having their own stitching. They can’t be completely removed without damaging the product. The merino is great.

Just a Tad Off The Mark
My ExpertVoice reviews are written as if I paid retail since the whole point is to along with making quality products we need to do whatever it is we do and do it safely affordable and available it also so we have experience and knowledge about products and brands that we can recommend and spread the word to people about so those people go to a retailer and pay full price. Now I love Icebreaker, I have acquired many of their products over many years and they’re almost always on point. I really wanted to love these boxers but to me they had one fatal flaw; the fabric and fit causes them to ride up and if boxers ride up they are nothing more than scrunched up tightie whities which I don’t want which is why I buy boxers. If the fabric held its shape a little better and wasn’t so loosie goosie it might have more integrity it might keep the legs from riding up deep into the crotch, and I mean they ride up deeeeeep!! The quality is as you’d expect from Icebreaker which is top notch. Just be prepared to be pulling wedgies on the reg when wearing these.

Great wool underwear
It’s the only underwear I pack for field work and personal travel. I’ve got a few pairs and they don’t stink like any cotton or synthetic underwear even after two days of sweat and work.

Comfortable
Very comfortable and true to size. They are on lighter side (as designed and advertised), so we’ll see how they hold up over time, but on a three day trip they did well and did not over stretch, even with a pack belt creating downward pressure.

I bought these to try out Merino Boxers. I find them to be very usefull and comfortable for trips where I know I wont be able to shower for some time. They are light weight and breathable leading to all day comfort while hiking long distances. My one problem with them is that the back has one central seam which can ride between your cheeks at times. It's not very noticeable most of the time while moving around and something I found I have gotten more used to.
