-
Flat yarn = More surface
Compared with traditional round yarn, ours is flat, so more surface sits against the skin and heat moves off faster.
-
Cooling that lasts.
Most brands use a cooling finish that washes out. Our fabric is woven with tiny channels in between that allows heat and moisture to escape.
-
Second-skin feel.
A low-bulk, fine yarn lets more air through the knit, while 360-degree stretch and a soft finish create a second-skin feel.
Plus built-in UV protection, from the yarn itself.
The Cooling Underwear
Frequently Asked Questions
It's built from our signature cooling fabric that is made to draw moisture & heat away fast. The barely-there fabric moves with your body, so there's no digging, no bunching, and no riding up — just an invisible, second-skin feel all day long.
Our advanced cooling fabric is temperature-regulating by design, helping cool skin temperature by up to 1° and keeping you feeling fresh and breathable — not just moisture-wicking like most cooling underwear on the market, but actively cooling.
Yes. The ultra-lightweight fabric and fine lingerie edges create a smooth, low-profile finish under most clothing, while helping the underwear stay securely in place without rolling or digging in. If you’re looking for a completely no-VPL option under very fitted clothing, we recommend our Cooling Short.
Our no-roll waistband is designed to stay put — no digging in, no rolling down. It's built with 360° stretch, so it flexes comfortably through bloating and everyday fluctuations.
No — the stay-put leg finish and no-roll waistband are engineered specifically to prevent riding up, rolling down, and wedgies, so you can move through your day without adjusting.
Our triple-layer gusset is longer and wider than most competitors, giving you extended front-to-back coverage. It's built with a 100% cotton loop surface knitted directly into the WhispAir Cooling™ base fabric — not a sewn-in patch — so it stretches with your body in every direction instead of staying rigid.
Yes — the gusset is engineered to help disguise camel toe without adding bulk or a padded, shapewear-like feel.
Yes — the cotton loop surface sits directly against the skin for natural, breathable comfort, while the cooling base fabric underneath manages moisture and adds stretch
Go with your usual undie size, and if you’re between sizes, size up.
The 360° stretch is built to flex through bloating and everyday fluctuations, so the fit adapts with you rather than feeling restrictive.
