Reviews

Great Product

"Very comfortable for exercise and daily use. I will be purchasing more!"

Becca (5/5)

Perfect, please don’t change these.

"These are perfect. I use these for running and skiing, the cut is excellent and the merino obviously helps with all day sports comfort."

Angela (5/5)

Best thong on the market

"I now have 5 pair of these - my absolute favorite. Soft comfortable merino fabric against your skin that breathes, flat smooth waistband that doesn't show through yoga pants, and perfect fitting. TTS"

Marla B. (5/5)

Love these! I always wait

"Love these! I always wait for a sale because they're pricey but this is my fourth pair over the last 2-3 years and they're all still going strong."

Lauren M. (5/5)

Great thong that doesn't dig

"Great thong that doesn't dig in"

Olga G. (5/5)

So comfortable!

"I've tried a different brand of merino underwear and this one was much more comfortable. Thin, breathable, with a higher percentage of merino. I'm usually an XS but purchased a small based on reviews. It fits well, but I'm wondering if I could have tried an XS. Either way, I love it! Would love to see boy shorts in the beige colour also. I agree that the gusset could be longer."

AK (4/5)

Highly recommended

"I brought a couple pairs of these into the backcountry for nearly two weeks, they were insanely comfortable during strenuous hiking and a quick rinse refreshed them so I could wear again, and they continued to smell and feel fresh the whole trip!"

Jen (5/5)

Looses Shape

"My partner really wanted to like this product; however Icebreaker's Siren series is prone to losing its shape and thinning out. This is annoying considering the price and ruins the comfort rating. I'm not sure how long they will last. On the good side they were initially comfortable."

A thong so great you will forget you're wearing it

"I'm a yoga teacher and I move a lot. This thong makes me forget I'm wearing underwear. Ha! That's a good thing. I love that it's merino. The band is good, it lays flat, and doesn't pinch. There is no scratchy tag! Thank you!! The thong is not itchy and it doesn't slip, slide, or bunch. It washes easily in the sink or washer on cold and dries within a day on a dryer rack. Next to going commando, these are the next best thing. Expensive? Yes. And they are truly worth it. Icebreaker is the best. But I've already bought 3. One more and I'll be able to rotate throughout the week with no problem."
