True Versatility

The women's Proton LT Hoody perfectly walks the line between an airy mid layer and a midweight softshell. It has the versatility to adapt to almost any climate, be it for rock climbing excursions around British Columbia or cycling trips near Lake Ontario. Its lining allows for optimal air permeability, while its shell is lightweight, stretchy, and offers enough weather-resistant protection to put up with rapidly changing conditions. It's also padded with a hydrophobic Coreloft™ Continuous insulation, providing generous warmth without the bulky weight. The women's Proton LT has the unique ability to self-regulate, allowing evaporation when you're overheated and heat retention when you've cooled off.

  • Women's specific trim fit
  • Coreloft™ Continuous insulation

Insulated Hood | No Slip Zip™ | Hem Adjuster

The women's Proton LT Hoody features a helmet compatible hood, which is insulated for warmth and has drawcord adjustability for a more precise fit. The front opening is a No Slip Zipper™, which has a teeth formation that stops itself from self-opening during activities and is backed by wind preventing dual flaps. The lower hem is adjustable via two separate drawcords, and the stretch-knit sleeve cuffs prevent cold air infiltration.
