These fit a little closer than ideal, for me. The stitching at the bottom (yep, right down at the South Pole) is not nearly as flat as I am used to with Icebreaker and I actually find it irritating. And a closer fit does not translate into better support, I am finding. Going forward I will stick to the relaxed fit version of these or the basic RedRam boxer briefs.

Great lightweight pants. Good fit, albeit a little boxy around my small hips, but that's pretty typical for me. Pockets are remarkably well positioned to balance ease of access and not having stuff spill out when you, well, get upside down. The little flaps on the back pockets are especially clever; subtle and functional. The integral "belt" works remarkably well. I had never heard of this manufacturer before getting these pants but they are definitely now on my list of trusted brands.

After enduring many years of technical shirts that last one, maybe two years before they stink so bad you have to pick them up with a stick I have found The Answer. Just this week I wore this while clearing snow (hot work) and then under my hockey equipment - NO STINK. I'm very impressed.

Very comfortable and warm for their weight. Fits a bit small - perfect on me but I am a "small" medium.

I can't say enough about this piece. The interior is a soft and light fleece material that feels good on the skin. In cold weather I use this as a second layer (on top of a 150g or 200g base layer, of course) and I Don't Get Cold. I am told that it looks like a Star Trek uniform but I think that's jealousy talking.
I will echo George's comment, below, that this piece fits "close". I am 5'10" and rather slender and a Medium fits me perfectly, whereas most medium-sized tops tend to fit a bit loose on me. If you don't like a close (but not tight) fit consider trying one size larger than your instincts suggest.

This is the one and only piece of Icebreaker clothing that I don't love. It's well made, warm for its weight, but the "one size" does not fit all. It's a stretch to wrap it around my pretty average-sized noggin.
