Feels great, but didn't last

I got these for motorcycle riding to try to eliminate swamp butt. They certainly do, but after a few motorcycle trips and laundry cycles they started to tear at the seams. I don't think I'd buy again due to this durability issue. Maybe they'd do better in a less demanding role instead of sitting on a motorcycle seat all day. Now they are used as backup underwear.

Excellent for travel!

Traveled to three continents in the past 12 months and learned to travel light. In particular, with merino wool clothing that require less washing; seems odd… but anyone who travels with merino wool clothing in various weather, will completely understand the antifungal, anti-stink, temperature adapting qualities of the clothing. Icebreaker boxers WITH FLY (really important) are a go to for travel and everyday wear. Fit from size chart is on point, I hesitate to put in dryer, so I air dry. Fabric holds up great.

These are just ok.

These are underwear, as expected… Maybe I was hoping for too much from a merino blend, and they are definitely slightly better than cotton, but I wasn’t too impressed. With many of the modern fabrics I’d likely just prefer a wicking fabric and something a little more stretchy. Won’t buy again, but if someone is looking for a thin, wool set of undergarments, these will likely fit the bill, but I wasn’t all that hot on them.

Best Underwear

Nothing beats merino wool base layers. Icebreaker got the cut right and the escape hatch comes in handy.

Must be worn inside-out.

Would be a great product, except for the care tag, which is printed on a hard and sharp nylon (?). It digs into the skin and causes irritation. It can't be fully cut out-my best efforts don't work.

Cloth is more substantial then prior versions, it doesn't feel like it'll tear a hole by just looking at it. It not as soft as the prior version but I'll trade that for much better durability.
