Perspiration is natures method of cooling us down, but it often leaves us feeling clammy and uncomfortable. We focus on creating garments using moisture-wicking fabrics to help stay cool, dry, and comfortable.

These scientifically better essentials are the perfect fathers day gift, or gear for a weekend getaway.

Why do some fibers wick moisture?

Water is polar,meaning thatwater moleculesstick like magnets to other polar molecules. Hydrophilic fibers like cotton absorb moisture due to their oppositional charge, while hydrophobic fibers like polyester repel moisture because they have no charge.

What's the best way to manage moisture?

Moisture regain is the ability to first absorb, thenrelease that moisture vapor into the air.The optimal fibers typically blend these properties of absorption and evaporation. Wool, for example, has 17% moisture regain - twice that of cotton!

The future is a blend.

As we think through long-lasting comfort in future fiber blends, finding this ideal combination of hydrophobic properties for evaporation and high moisture regain for vapor steam will be critical.
