Baselayer technology makes for one great boxer.

Utilizing the same design technology employed for its high-performance baselayers, Icebreaker infused the Men's BodyFit 150-Ultralite Anatomica Boxer with all the same comfort and functionality. The super-soft jersey knit merino wool is very lightweight, breathable, and its anti-microbial properties fight odors―great if you're working up a sweat or on a backpacking trip where you need your undies to last for the long haul. And for less adventurous days, these same features make for all-day comfort. A little bit of Lycra adds stretch for a contoured fit, the satin jacquard waistband keeps things secure, flatlock stitching prevents chafing and a contoured pouch with fly makes things easy when nature calls. After being spoiled with this level of high-performance comfort and easy functionality, you'll have a hard time settling for anything less.

  • Ultralite merino wool jersey with a hint of Lycra stretch

Fantastic Under Trousers!

  • Familiarity: I've put it through the wringer
  • Fit: Runs small

So soft and comfy for your nether regions. Love the material. Fit is a little small but not too terribly so. Waist size 36 and i got the large, they fit although a little tight. Still a premium boxer. A little shorter that some, closer to a brief than a boxer brief but not so much that i would complain. Great colors too, and the color doesn't fade in the wash. Will def buy more! Well worth the price.

Fit change

I've had a few pairs of these before, all fantastic. They have recently redone the fit and it seems to be more wedgie causing.

As Tony the Tiger would say, if he wore merino wool boxers. I like these a lot - fit, style. Yep they're shorter like the pic shows. 33-34 waist, medium fits nicely.

I wouldn't wear these on longer hiking trips as I like longer, tighter boxer briefs to prevent inner thigh chafe, but for everyday use these are comfy. These do fit snug enough, I hate baggy boxer briefs.

I absolutely love icebreaker. I'll start with that. The material is amazing, and feels great.
Smell, well.. not there.
Fit.. is absolutely terrible to me.
I was looking for a boxer brief.. these are so short in the leg they might as well be briefs. They do not maintain shape too well over a period of one day, let alone 4+ days.
I really wanted to love these, but can't say i do. Just bought Stoic boxer briefs and waiting on them to try. W
