I've never been a huge fan of thongs...until I discovered Icebreaker's. Comfortable breathable, flattering, AND made from Merino wool? The perfect panties. I own both Black and Fawn Heather and have worn them to yoga and while running, backpacking, and biking. I am positive they will be just as perfect for backcountry skiing this season. Also, they dry really quickly (I was able to hand wash them and wear them twice on a recent trip). Tempted to buy two more pairs. Highly recommend!

I ordered the XS because that’s what was left. I was skeptical that it might be too small; but they fit perfectly. I’m 5’3” 125 lbs. Love’em!

I didn't even know I needed Merino underwear until these - they're perfect for travel, backpacking, biking... everything. I'm not wool's biggest fan, but they're not itchy in the slightest and they dry incredibly quickly.

But seriously. These are the most comfortable, practical idea for active ladies. The Merino fabric is incredibly comfortable and noticeably breathable, washes really well, and dries super quickly. I brought a few pair of these along on a four day trip in the desert and they were so much more comfortable than my everyday cotton thongs. The fit is great too - the are a flattering rise that doesn't come up too high.

I have several pairs of Icebreaker underwear already. I love the thong as I can wear it to go running/yoga and not have to be constantly picking a wedgie and worried about lines showing.
The anti-microbial feature and Merino wool add extra comfort. Great for running ,backpacking, yoga, and so much more!

Pleasantly surprised by these! They stay in place all day, aren't constricting, and wick away moisture as needed.

I have ordered several pairs of the Icebreaker Hot Sprite pant that I've loved, but I did get a little [anite line wiht some jeans, and wanted to try the thong style out for running and spandex wear over top. Not only is the fit perfect, they are equally as comfortable as the Hot Sprite that I have, and now NO underwear line! Perfect for running, or wearing hiking the grand canyon like I did!
A must have for lightweight backpacking, they only weigh a couple grams!

I was leary when I bought them but they far exceed my expectations. I love how comfortable and breathable they are. They do run large so size down.

Icebreaker does a stand out job with their undies, and these are no different. Thongs are tricky. It's all about the fit. They can be tight and restrictive, or so loose you feel like Borat at the beach. These are just right. I'm a medium-sized lady, and the medium is perfect. It doesn't pinch too much and doesn't ride too high. They sit right where most of my pants do.

As for the fabric, if your not familiar with merino, it's THE fabric for intimates, especially if you'll be camping or backpacking. You can wear them for days, and still feel fresh and comfortable. They are one of my most important pieces, when backpacking.

Also, Icebreakers quality is All-Star, without a doubt.

I don't know if anyone else shared my immediate skepticism about wool underwear. Wool sweaters yes, but underwear?

Oh how wrong I was. If you know Icebreaker's merino wool you will know, but for you others let me describe the softness, pliability, wicking, and general wonderfulness of these underwear. It almost feels like I'm not wearing underwear. They are so awesome, I'm almost sad when I wear them because then it has to be at least another laundry load before I can wear them again.

The sizing is true to size. The slightly thicker top band keeps them from rolling or going rogue during the day. They are just so soft and comfortable!

Love them! And if you love yourself, treat yourself and make sure you have underwear that loves you too.
