The Helixir Shell jacket is our most advanced three-layer waterproof jacket, designed to protect you from the whims of the weather without hindering your movements. It combines a high-performance inner membrane with Spectra fabric, one of the lightest and strongest fibres in the world. More durable than polyester and stronger than steel at an equal weight, this provides protection that won’t let you down during your climbing adventures. The cut of our Helixir Shell jacket is specifically designed to promote freedom of movement, featuring pre-shaped sleeves and shoulders that ensure maximum mobility. The elastic waist guarantees lasting comfort, while the ergonomic hood, compatible with a helmet, keeps you safe from the elements.
