Raide TrailTech UL Shell Jacket - The Lightest 3-Layer Shell Available at 128 Grams

Built for the runs where you shouldn't have to choose between a rain shell and running light. The TrailTech UL Shell packs into a 3"x5"x3" pocket sized to sit in the front of a running belt, so it's there the moment a storm rolls in. 128 grams. The lightest 3-layer shell available. Meets UTMB rain jacket requirements.

45gsm Japanese 3-Layer Fabric with 5-Micron PU Membrane

Japanese 3-layer fabric built around a 5-micron PU membrane delivers full waterproof-breathable performance at just 45gsm, achieving a 20k/20k waterproof-breathable rating without the usual weight penalty. PFAS-free DWR treatment keeps the environmental credentials as considered as the technical ones. Fully welded seams throughout eliminate leak points across sustained rain and storm conditions.

Belt Integration with Internal Stow Pocket

Packs into its own internal pocket at 3"x5"x3" packed dimensions, sized specifically to sit comfortably in the front pocket of the Raide LF 2L belt. Light enough to carry on every run without thought, there the moment conditions change. No more choosing between packing a shell and running in a belt.

Cape Mode with Laser-Perf Venting

Cape mode extends coverage across the back during high-effort running in rain. Laser-perforation ventilation manages heat build-up during sustained running efforts without compromising waterproof integrity. Fully featured hood with elastic cord cinch provides added protection in heavy wind and rain. YKK reverse coil zipper with Dynapel pulls completes the construction.
