Why We Like The Siren Hipkini Underwear

Icebreaker made the Siren Hipkini out of ultralight merino wool with a touch of Lycra for a great fit. Soft and gentle against your skin, the Siren has a low rise and full coverage in the back. The merino naturally deals with odor so you can get through multi-day backpacking treks and hut-to-hut ski tours without using up precious packing space with extra undies.

The product offers excellent comfort, breathability, and versatility. The merino wool material provides effective temperature regulation and odor control, even during physical activities. The underwear has a well-fitting, durable design that stays in place without causing chafing.

Great underwear

I’ve had these underwear for several years now. They’re still my favorite and they’ve been quite durable!

Wool is undefeated

Best fabric for outdoor activities, especially as a panty. Wool is the perfect fabric for travel, & outdoor activities—it’s microbial, so it keeps odor at bay, and insulating in case of cold conditions. Breathability as far as moisture from sweating is another great quality for a pair of undies.

No smell but durability issues

This works great fr travel and outdoor adventures because the material is soft and merino wool's antiodor/antibacterial properties. The biggest flaw these products have is durability. The wool easily loses its stretch and comfort after the first day. By the second day of wear, the underwear begins to get loose and ride up. or two

Great fit and color but fabric wears out very very quickly and develops holes easily

Love the Product, Not the packaging

I love my icebreaker undies! I've ordered from this company many times, but was so disappointed to find each pair of underwear in a separate box this time. It felt wasteful and unnecessary, why?

Good underwear, but not perfect

[This review was collected as part of a promotion.] They are great in theory...Breathable - Light - Coverage. The 2 issues I have are: 1 - inconsistency in shape of underwear - some too big, some smaller. 2 - The biggest issue...... the edge or seam of underwear can start to chafe your bum crease. It can feel sharp and hard edged - And cuts into your skin at times on your bum! I will go back to the bikini's next time. Please soften the edge!!!

I like these but prefer the 125

I bought these and the 125, I can't tell a difference in the performance is different environments but I prefer the feel/fit of the 125s.

Happy with the return of the hipkini

[This review was collected as part of a promotion.] After reading the reviews I hesitated to purchase. The last generation of hipkini underwear fit my body perfectly and recent reviews declared this generation completely different. Couldnt resist. The feminine pink color tempted me so I ordered some. The fit perfectly, just like the others!! The pink is a pretty shade and I am delighted to have feminine looking underwear at last. The last generation offered all drab colors, imo, so having the pink has rejuvenated my under garments. Thank you Ice Breaker. For the record, I am 59, 135 pounds, 36C. Size large underwear fit nicely.

The best ones

[This review was collected as part of a promotion.] I ordered merino wool underwear from a few different brands and the icebreaker ones are my favorites. My hips are 43" and the large fit perfectly.

Larger than expected

[This review was collected as part of a promotion.] Based on prior underwear purchases from icebreaker I ordered size "S", but I found these sit quite high on my hips, so the fit feels like a granny panty as opposed to a sport panty
