Game changer for comfort in hot/humid weather
Game changer for comfort during workouts in hot/humid weather. Contributes almost no insulation, so it's not any warmer with it on. When you start to sweat, the outer part of the honeycomb wicks the sweat into the center where it holds the moisture and lets it evaporate, cooling you but keeping you comfortably dry. The non-clamminess is remarkable. A perfect summer base layer. Paired with the long sleeve house jersey and it disappears on the ride.

Based layer
Nice color and the dead stock material is cool. I’m 6’3”, 175 and wear a 40L suit jacket. Went with size M and if I bought it again I might try a S. The M isn’t too big, it just bunches up very slightly with some of my bibs.

Perfect light base layer....
Perfect light base layer. Simple, yet Ornot seems to do even the simple things better. Wore it last weekend at a very cool, wet, windy Barry Roubaix under a Merino Grid jersey, topped off by a Micro Climate jacket. Perfect all day long.
