Many riders find the idea of layering up when it's hot out completely counter-intuitive. Why put on more layers when we're overheating in our jerseys already' The answer is, technology has gotten cool --really cool. The Pearl Izumi Transfer short-sleeve base layer is the perfect example, with summer-weight wicking fabrics that pull moisture away from your skin, and evaporation, boosted by activated charcoal, cools the air, channeling the colder air back towards your body, reducing your core temperature for a more comfortable ride. The Transfer Short Sleeve base layer is an exceptional option when you need a little something to help you cool off on the hot days, but is versatile enough to be used when it's cold out too. Simply throw it on for a next-to-skin layer underneath your jersey when it's cool out to eliminate the cold air gaps between your skin and fabric of your jersey, and keep the chill off of your skin. Because of the evaporative technology it'll work it's hardest to keep you dry, and with the proper layers on top, you'll stay toasty and dry instead of cold and soggy through your fall and winter rides. It's hard to beat multi seasonal versatility.
