"I but this, because I try to travel light these days. I only bring three of this underwear. One to wear, one to wash, and one extra clean just in case. And that’s all I need for even a month trip. I also bought a bra and I only need two of it. Very happy to find this."

"These are great for multiple days in the outdoors, breathable and quick dry making them good for swimming in lakes and also washing in the outdoors."
— Janine (5/5)
"I've exclusively switched to these underwear a year ago and they are still holding up so well with air drying. The fit is extremely comfortable (no wedgie) along with being breathable through activities and heat. Definitely recommend this brand and style for anyone also looking to make the switch to wool underwear!"

"These are nice quality. Unfortunately just a bit loose so I will save them for when my weight fluctuates up."
— SSS (5/5)
"These underwear don’t dig in, ride up, or pinch anywhere. They are soft, comfortable, cover my butt, and are breathable! I have an athletic build, my hips are 39 inches and I wear a medium. These are my everyday underwear and I just love them."
— Tara (5/5)
"Warum gibt es das Doppelpack nur in schwarz? Schön wäre auch dunkelblau, beige, hellblau. . . Die Unterhosen an sich sind super, ich möchte keine anderen mehr tragen."

"I have converted to exclusively wearing the Icebreaker siren hipkini all year! Love them super soft stay put not hot. I don't put them in the dryer but they air dry super fast and last a long time. You can't go wrong with these!"

"These are great hipkinis. The quality is fabulous. But why such boring colors? And I miss the grey with the black band! Please, ladies like lovely undies with fun!"
— Tina L. (5/5)
"I originally bought the siren bikini & I loved the comfort and feel, they were just a tiny bit low waisted…. I then decided to try out the siren hipkini and what a world of difference. They are so soft and comfortable & very breathable! They don’t trap scent and I feel fresh even after wearing them for a day of hard work!!!!"
