More information on Undergarments:
Often overlooked when layering, undergarments are the first thing that you put on (hopefully...) and the last thing that you take off. If you're taking the time to properly outfit yourself with the right base and middle layers, don't stick with those cotton undies -- make the move to the tech fabrics.
Patagonia's Active Undergarments may look like plain old underwear to you but they're definitely not. Designed and crafted from performance textiles they're the most breathable and quick-drying underwear you'll ever try. When worn next to the skin, they feel dry when you're hot and help preserve body warmth when you're not. Nothing beats them except maybe... well, wearing nothing?
Patagonia offers undergarment options for both men and women. Made from the best moisture wicking fabric, these breathable boxers and underwear are made to keep you cool and dry. Stretchy, seamless and flat lock seamed edges ensure a garment that won’t chafe or constrict. Polygiene® permanent odor control means less washing and longer wearing- great for those long offshore Ocean Races.
