DropTemp™ Technology
The quickest way to cool.
DropTemp™ boosts your body’s natural cooling capacity by (drumroll) evaporating your sweat. (Ta da!) It’s the whole package when it comes to keeping yours cooler.

How it works: science, obviously.
When you make friends with science, anything is possible. DropTemp’s fabric structure evaporates sweat, while you sweat. And since we’re dropping things, here’s the mic.

FIG. 1 QUICKER COOLING
Sweat is good. But not when it’s stuck next to your skin. DropTemp™ wicks sweat quicker than the “experts” in cooling. Cool just got cooler.

FIG. 2 WICKING STRUCTURE
Science not chemistry. DropTemp™ uses a unique structure to move moisture off your skin and keep you cool. And unlike chemical cooling treatments, our structure sticks around day after day - wash after wash. Once again, it’s wicked quick.

FIG. 3 EVEN DISTRIBUTION
With sweat distributed through the fabric evenly, it’s primed to evaporate, and drop that temp. Any guesses which cooling fabric is quicker when put to the test? We’ll give you three.

FIG. 4 BE YOU, BUT COOLER
Go from hot and wet, to cool and dry, fast and faster.
The #1 cooling fabric.
DropTemp™ is lab-tested.
No one expected us to show up like this. Not even us. But the test results are in, and hot damn, do they look good.
Don’t take our word for it. DropTemp™ is lab-tested. Evaporative cooling experts out of Boennigheim, Germany have set the record straight. When it comes to cooling in underwear and performance apparel, DropTemp™ is on top.
