The Base Layer 0 Mesh is Q36.5's lightest base layer, built for warm-weather rides where airflow matters most. An open mesh knit spans the body for maximum breathability against the skin, while a lightweight polyamide and polypropylene blend helps manage moisture and regulate body temperature through the hottest efforts on the bike.

Seamless construction eliminates side stitching that could rub under a jersey, and the sleeveless cut keeps the shoulders and arms free for a natural pedalling motion. At 51 g, the fabric adds next to no bulk, so it layers cleanly beneath a jersey or pairs with additional base layers on cooler days.
