The Yeti Men's Turq Air Short-Sleeve Jersey remains true to its name with tiny air perforations throughout for increased breathability in sweltering conditions. This means you'll remain pleasantly cool and comfortable when temperatures soar in summer, keeping your sweating in check when you're riding along exposed ridgelines and desert environments. Polygiene odor control prevents funky build-up after a long day of shredding. Polygiene is a permanent treatment, so you won't have to worry about it washing out after a couple of uses. And seeing you'll be wearing this in summer, it's boasting UPF 30+ to ensure full protection from harsh UV rays.
