Cyclists are passionate about base layers. Bet everyone you know has a favorite, a go to they'd prefer to have under their jersey. In their quest to make ever better cycling clothing, Giordana has focused attention on that layer between your body and your jersey. The result: the Super Light Weight Sleeveless Base Layer. They have taken the Dryarn fiber technology of their OverUnder base layer and gone a different direction, making something for the days when the choice is between nothing under a jersey and something light. In those conditions, the base layer needs to be ultra thin, fit well, and wick like nobody's business. To that end, this top has been made with a tubular knit think socks, for better fit, has incorporated multiple zones in the weave, for just the right amount of protection, and has anti bacterial properties built in so you can wear it all day and not have it attack your nostrils a few hours in. The Giordana Super Light Weight Sleeveless Base Layer comes in White. There's light elastic at the arms and waist. Sizes run from Small to X Large.
