Short sleeves on a base layer give you a bit more warmth on those transitional days, days when it is pretty cold at the start, and there is a promise of greater warmth. Never hurts to have a little extra protection. Besides, some like to attach their arm warmer grippers to the sleeves for a little more security there, too. The Giordana Super Light Short Sleeve Base Layer offers you all this, plus their tubular-knit, almost seamless build, and the pleasures of Dryarn, a new micro fiber, also found in their Over/Under base layer.
Dryarn is a new kind of polypropylene fiber. One that moves moisture quickly and efficiently away from the skin, and is also feathery light, has excellent stretch, and anti-bacterial to boot. It will help create a comfortable microclimate between your skin and your jersey thanks to its properties, plus the zones of differing thicknesses (or meshiness) around the top. Thicker over your chest, but thinner on your stomach; thicker on the front of sleeves, thinner around back.
The Giordana Super Light Weight Short Sleeve Base Layer comes in White. There's light elastic at the arms and waist. Sizes run from Small to X-Large.
