For riders who prioritize on-bike performance and durability over budget, 7mesh offers clear technical advantages.

The Castelli Flanders Warm Long Sleeve is the market leader for cold, wet‑weather road riding thanks to its robust windproofing, water‑repellent treatments and race‑oriented fit that prioritizes warmth where it matters. It sacrifices a degree of breathability versus Craft and Sugoi in exchange for extra protection, but often undercuts premium race kits on overall value for riders whose priority is weather defense rather than minimal weight.
