I've been wearing the same Performance mesh sleeveless tees for years. In all weather, all year until temps hit 90, then I go without. (Don't worry, I bought enough pairs that I always put on a clean one.) One of the best pieces of cycling gear I've ever owned. Never felt any need to look elsewhere since I bought them. (Performance apparently did feel that need and have carried other tees but not those since. Too good - customers weren't coming back because they held up so well?)
