Unfortunately this year's Icebreaker wool boxers have some changes for the worse: a far less comfortable elastic band around the top (once soft, now stiff), an awkward fit (less supportive), and a larger number of (uncomfortable and unnecessary) tags.
They are still made of the same highly functional merino wool, however. For those who have never tried wool boxers, they are soft, grow softer with every washing, can't be dried in the drier but dry overnight, don't generate static electricity, and are equally comfortable under running tights, jeans, or even dress clothes.

They have made changes in these for the worse and not fixed the problems.

The rise of icebreaker boxers and leggings is really high...like "mom" pants up to your bellly button high. They stick out of most jeans by a good inch.

The waistband has changed to a hard, plastic-like and stiff material. The old waistband was much more comfortable yet it stretched out easily.

The durability is poor as well. Unraveled seams and holes worn in is common.

While its not a big deal and I cut them out, putting in 4 tags in a pair of boxers is a bit weird as well.

Icebreaker charges way too much for the quality and feature set.

I am done with icebreaker.

Very comfortable, minimal shrinkage after 2 washings, plenty of room...only gripe is the two tags on the seams...itches the cheeks. Why would you design these great base layers with these drawbacks?

These are very comfortable, minimal shrinkage after 2 washings and plenty of "room". Only drawback is all of the tags...there are two on the seams that right on the cheeks and itch...I don't see any reason for the tags.

Got two of them and they are great, Will take them for a week-long backcountry trip in northern Sweden in Mars, cold and windy weather. However, so far so good, can strongly recommend them.

in terms of price, not in the lofty neighborhood of Ibex or SmartWool, but nearly as well made as the aforementioned.

As others have noted, they ride a little high. Also the elastic band bends in the middle in an odd sort of way. IF they weren't made of super nice merino...

Just got back from a week-long sea kayaking expedition in the Everglades. I wore these boxer briefs for the duration of our trip (occasionally rinsing them in the ocean) and they didn't stink one bit! They did a great job wicking sweat away and didn't really get too hot despite the fact that my lower body was in the kayak with a spray skirt. Hope this helps!

OK, so to retort my own critical review ("Grandma's bloomers"), these are the business. Turns out Backcountry must have messed up the sizing chart -- I looked on Icebreaker's website & they had a much more reasonable & normal sizing chart. It says L is my size; no kidding. So I re-order them in L and whaddaya know, they fit like a glove, or, some other thing that also fits closely down there. Yeah, these boxer-briefs are awesome. Get some. You'll understand. Can I give these 6 out of 5?

Great underwear, if they' only move that tag on the inner seam or use some other material. great for traveling. Wash it and hang it out to dry. Usually dries in a day.

Bought a few pairs of the Icebreaker BodyFit200 Boxer back in the summer. Sooo comfortable. Feel like silk after a few washings.

What is with the sizing? I have a 36-37" waist and normally take like a L in underwear. The guide here says that a 33" waist is a XXL. And that's as big as they go. Say what?!?!

I put them on and the waist is a little snug, but the rest of the brief fits like pantaloons. I feel like a darn pirate. Arrr!

The photos here show the briefs as being snug fitting, well for that to happen, the model / mannequin must be getting cut clean in half by the waist band.

I have a drawer-full of Icebreaker shirts, which are wonderful. What's up with the fit of these things?

Best underwear for travel, doesn't itch. Maybe I got last year model, looking at previous review, so it's hard to tell, but mine hold pretty well so far, no tag itching, doesn't climb in your crotch, doesn't SMELL, but you still will have to change sometimes.

Very comfortable, probably will ruin me from wearing cotton boxers.

Great Fit and extremely comfortable. I also have the bodyfit 150 and like the bodyfit 200 even better! Worth the money as they last forever! Don't pay any attention to the Icebreaker size chart. Its wrong.

Just recently got introduced to ice breaker stuff.. it's awesome.. dries fast.. and retains very little smell. This underwear is great in those respects too. However, for athletic stuff, I thought the fit could be a bit more snug. But still a great product.

I just want to mention that as close fitting as these are...they keep me cool and dry in the warm weather and warm and dry during the cold days. And I never seem bunched up!
Love these!!!!

I picked up a pair to test out and I love them. I bought the mediums and they fit perfectly. These boxers are not loose fitting, however they do allow for free movement. I've worn them running, ski touring (including some steep uphills, when the boxers didn't impede movement). I've also worn them as daily boxers and they've performed all tasks with no complaints.
