These are great for breathability, use instead of swim trunks in the sauna, they really don't compare to any others on the market. The only thing is I wish they lasted longer for the price, they tend to break down sooner than expected

I have a problem with sweating too much all the time and these briefs really help. I feel dry throughout the day finally!

Same great underwear but they've made the tag larger and of less comfortable material. I guess the thing to do now it cut them out. I preferred the old smaller, softer tag. We'll see if it becomes an annoyance and I attempt to cut it out without ruining the stitching on the band.

I've been using these merino boxer briefs on multi-day backpacking trips with a simple rotation system - one pair for hiking, one for sleeping. They're also great for day hikes and regular outdoor activities. What works well: The quick-dry performance is excellent after sweaty trail days. The odor resistance is genuinely impressive - crucial when you're days away from laundry facilities. I was pleasantly surprised that they don't feel hot or itchy against the skin, which had been a concern with merino wool. For day use or hiking, they're really nice. Minor consideration: The leg holes do tend to stretch out over time and lose their shape. Because of this stretch, they become more like boxers than briefs over time on the trail. It's not a major issue, but perhaps a little more Lycra in the leg holes would help with long-term shape retention. Bottom line: These are excellent performers for backcountry use, particularly for their moisture management and odor control. The gradual fit change from briefs to a boxer-like feel is a minor trade-off for otherwise outstanding comfort and performance. Highly recommended for serious backpackers who prioritize comfort and hygiene on multi-day adventures. Best for: Multi-day backpacking, day hiking, any outdoor activities requiring odor control and quick-dry performance
