I want to replace all of my underwear with these!
I'm obsessed. I am replacing all of my thongs with these. They keep me dry, and I can wear them multiple days when backpacking. Good for everyday activities too. Please make them in new colors!

We've been complaining of the small gusset for 5+ years
Reviews from at least 5 years ago have been complaining about the SMALL GUSSET. Seriously, IB? Shame! Please redesign your underwear with a properly sized gusset.

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
[This review was collected as part of a promotion.] 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.

Great fit and comfort in a thong!
[This review was collected as part of a promotion.] I wore these for a week-long hiking trip and absolutely loved them! Super comfortable, wicking, and quick dry after handwashing. Will definitely buy more - thanks for a great product! :)

The best out there
[This review was collected as part of a promotion.] I originally purchased 3 black for rowing, and came back years later to buy more in nude to wear with white linen pants and other more transparent bottoms. Very happy with the cut and quality of the old pairs and hope the new are the same. For reference I am 5'-5", 130-135 lbs, 40" hips and 30" waist, athletic/curvy build.

Comfy
[This review was collected as part of a promotion.] I've only worn these twice but they're comfy and fit well. Fitted but not too tight. Size S -a 26/27 waist/size 2-4. The pink is pretty. My only complaint-that long tag!
