I would buy 100 of these

[This review was collected as part of a promotion.] I wear these every day, and especially for running. They fit perfectly, they are easy to wash, they are seamless under clothes. The pink color is super cute.

So good

[This review was collected as part of a promotion.] After buying some merino underwear from a competitor who advertised to me on social media, I almost swore off wool undies. Their underwear were scratchy and too bulky. But I love the wicking quality, so I gave icebreaker a shot and I'm super glad I did. I'll buy more - I don't ever want to work out in synthetic underwear again after wearing these.

Best Underwear

[This review was collected as part of a promotion.] Love this underwear. It has the exact cut I want and is perfect for summer or year round. I'm slowly collecting as many as I can. Love seeing the new seasonal colors!

Everyday favorite

[This review was collected as part of a promotion.] So comfortable that I do not intend to buy another type of bra again, especially if more cute colors are on the way

All I want to wear now

[This review was collected as part of a promotion.] Comfy & don't show panty lines with leggings. They do not cling and stay feeling dry when exercising or worn all day. Minus a star for the gusset, it definitely needs to be longer. Overall, LOVE them

I was skeptical of merino underwear, and now its biggest fan

Soft and not itchy at all. Breathable and all around great. The Siren Thong is the most comfortable thong I have ever worn. Siren thong by day and the Sprite Hipster to sleep in.

Eliminates Odor & Wicks Sweat

[This review was collected as part of a promotion.] Bought these for long travel days and outdoor activities. They have held up great so far and seem to help with odors and wicking sweat quite well. I sized up to M. Fits small but works.

My new favorite underwear!

[This review was collected as part of a promotion.] These are the most comfortable and breathable underwear I've ever worn. I can't wait to swap out all my other underwear for these. They fit true to size.
