Smartwool Intraknit Active Skullcap Black, One Size

Designed to keep us warm during cold-weather rides, the Smartwool Intraknit Active Skullcap is an under-the-helmet cap to regulate our temperature when working out on the coldest of days. The Merino wool, Lyocell, polyester, and elastane blend makes for a stretchy, warm, and moisture-wicking design that works hard to keep us comfortable. The fitted design and minimal seams mean less irritation when wearing a helmet, and the thin, stretchy construction ensures we will forget the skullcap is even there.
