Sizes have gotten smaller
[This review was collected as part of a promotion.] I've bought the same underwear in the past same size and this time around it appears the measurements have at least an inch missing in fabric/waistband compared to my other size small.
It started out well....
But then they developed a hole after 6 months in the underwear rotation. These were one of two pairs that also went on a thru hike with me, and they were great during that time. I was hand washing and air drying, and since getting off the trail, they've been machine washed, hung dry. Icebreaker is usually a great brand, so I am disappointed that these haven't held up.
My go-to for travel
These are the underwear I consistently reach for when I travel. They are lightweight, breathable, and stay funk free. I can wash them and hang to dry at night, and they are ready to go the next day. I've tried merino wool underwear from other brands, but these are the best, IMO - I find compared to the other brands they are more breathable, dry more quickly, and last a lot longer. Another high quality product from Icebreaker!
My favorite undies
[This review was collected as part of a promotion.] I started to solely convert to wool undies a few years ago because they're far more durable, easy to sink wash on vacation, and much less likely to get icky on long backpacking trips when no sinks are around. Icebreakers are my favorite - they've held up to the test of time and the elastic bits have stayed tight (unlike my Smartwool undies which have become saggy over time). Highly recommend!
Excellent purchase
[This review was collected as part of a promotion.] I've worn these on several trail runs and am in love. They are so lightweight I forget I'm wearing them. They do offer less coverage than some styles, but I personally like that and appreciate that it's a smaller cut but not a thong. For reference I bought a size small and I'm a 26-27 waist/size 2-4. Five stars, definitely ordering more. And the purple color is beautiful.
Second time buying a slew of these.
[This review was collected as part of a promotion.] My first six pairs are three years old and a couple have started to develop holes so I bought a replacement six. These are all i wear so I'm coming up in 200 washes and wearings . I don't baby them other than trying to keep them out of the dryer! Oh and the replacement six will stay in the boxes until they're needed!
Not enough coverage in back for curvy figure.
[This review was collected as part of a promotion.] Generally felt good around legs and waist, so I'm assuming this is a good product for the right figure. The back height is about 1" -1 1/2" too low for my curvy figure. Wish you had a true flattering FRENCH cut in the line. There are no comfortable or flattering options for my body type.
I never thought I would buy wool underwear but a coworker of mine recommended them. I like the fit and their softness and wicking capabilities. Unfortunately I was a little let down by the odor control - I had thought it would be better. Overall, glad I purchased.
Winner
I've tried many styles and a few different brands for wool undies, these are by far my favorite so far. No tight seams digging into your bum cheeks. I'm 5'5" 130 lbs athletic (size 2 in jeans) and the smalls and mediums of these both fit (the medium fits better).
Runs Small
I haven't gotten to use these yet, but they do run small. I'm usually a Medium bottoms, but like a lot of bikini bottoms, I find that I end up having to size up to fit my larger rump. They seem like great underwear moisture wicking underwear though.
