Alpinestars Stella Radium Tech Hoodie

Women's windproof armoured hoodie for town

The Stella Radium Tech Hoodie is the women's cut of Alpinestars' low-profile urban riding hoodie: a 3-layer windproof tech shell that bonds the outer textile, membrane and lining into one light layer, with Nucleon Flex Plus Level 1 armour at the shoulders and elbows placed for the female rider's anatomy. It's certified to EN17092-4 Class A and is compatible with the Tech-Air 3, Tech-Air 5 and Tech-Air 5 Plasma airbag systems.

Sizing and fit

Sizes XS to 2XL in a single colourway. The women-specific athletic fit has ribbed stretch cuffs that seal out wind, reinforced stitching at the shoulders, elbows and pocket edges, and a hood management system with an attachment loop and front pullers so it doesn't flap at speed. There's a sealed-seam waterproof internal pocket and two hand pockets, plus inner snap points to connect to compatible Alpinestars pants. Men's version: the Radium Tech Hoodie.

Goes with

Pair it with Stella Callie Denim Pants or Stella Flex-AST Leggings and the Stella Copper Glove. For airbag protection add the Tech-Air 5 Plasma.
