True Versatility.

The women's Proton LT Hoody toes the line between an airy mid layer and a midweight softshell. This coat has the unique ability to self-regulate, allowing evaporation when you're overheated and heat retention when you've cooled off. Its lining allows for optimal air permeability, while its shell is light, stretchy, and delivers enough weather-resistance to handle rapidly changing conditions. It's also padded with a hydrophobic Coreloft Continuous insulation, producing generous warmth without the bulk. This jacket features a helmet compatible hood, which is insulated for warmth and has drawcord adjustability. The front opens with a No Slip Zipper that has teeth patterned to prevent self-opening. A wind blocking zipper flap prevents cold air infiltration.
