The Assos SJ BlitzFeder Evo7 is the lightest long-sleeve shell, in terms of both volume and protection level. The perfect, light shell jacket for training or racing during the warmer, drier months of the year.
An ultra-compact long sleeved wind shell which easily packs down small enough to fit unobtrusively in a jersey pocket. We never cease to be amazed how a product that packs so small can give so much protection, and this sJ version even comes with full-length sleeves.
Designed for milder weather, the blitzFeder isn't intended to insulate, or to be fully waterproof - it's aim is to prevent wind chill, particularly on long descents where that extra arm protection is much appreciated.
An ideal backup/emergency jacket for training or racing, this is one of those staple products that belong in any cyclist's wardrobe (or rather, back pocket).
