Design Philosophy Technologies developed by Endura for the most demanding races in professional cycling go straight in to the flagship Pro SL collection. This lightweight waterproof shell jacket is packable enough to fit in a back pocket but waterproof and breathable enough to keep you comfortable through a big day in the saddle. Multi-Panel Construction A pre-shaped, multi-panel construction and carefully positioned stretch panels provide a fantastic non flap fit on the bike. Additional features include a small external gel pocket, rear jersey pocket access zip and incredible detailing throughout. ExoShell40 Waterproof Fabric Using an innovative 3 layer construction and weighing in at only 70gsm ExoShell40™ delivers a formidable combination of minimal pack size, immense breathability and high durability. The key to the ExoShell40’s impressive breathability rating of 40,000g/m²/24hr and high waterproof rating lies in the ultrafine, fluorine free membrane, protected by a superfine denier tricot laminate and impregnated with a proprietary compound enhancing moisture transfer. 90 DAY SATISFACTION GUARANTEE So confident are we in this product that, if you are not entirely satisfied with it then we offer a no-quibble refund or replacement policy within 90 days of purchase.
