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.

Here's what customers have to say
The product is praised for its comfort, breathability, and versatility. Reviewers say the underwear is soft, lightweight, and stays in place well during physical activities. Many customers have replaced their other underwear with this brand, citing the merino wool's ability to regulate temperature, wick moisture, and resist odor. The hipkini style provides good coverage without being too bulky. Customers also appreciate the quick-drying feature, making it suitable for travel and outdoor activities. Some noted the underwear can be delicate and prone to developing holes, but the overall quality and durability are considered worth the higher price point. Customers highly recommend this product for everyday wear and active pursuits.

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
