Chase boulders, alpine views and rising trout without letting cold rain end the day. The Insulated Boulder Fork is built on Patagonia's low-profile Boulder Fork rain platform, adding warmth to a waterproof shell so you can stand in the weather from the fork in the trail to the places less traveled, and back again.
The jacket meets Patagonia's H2No® Performance Standard with a waterproof/breathable 3-layer shell built from a 3.7-oz 30-denier 100% recycled polyester ripstop face, a polyester membrane and a recycled polyester tricot backer. The fabric, membrane and durable water repellent (DWR) finish are made without intentionally added PFAS, delivering long-term waterproof durability with streamlined, packable features.
Standout features:
- Adjustable hood with visor — low-profile hood with a laminated visor and single-pull adjust sheds water, aids visibility in poor conditions and lies flat when not in use
- Watertight zippers and pockets — exposed, waterproof center-front zipper, a left-chest zippered pocket and two watertight, zippered handwarmer welt pockets large enough for a fly box, map or notebook
- Stormproof cuffs — minimal cuffs with streamlined hook-and-loop tabs seal out weather
- Adjustable hem cinch — drawcord routed up through the front pockets keeps out weather and reduces bulk under a pack waistbelt
- Minimalist, packable build — streamlined, essential features keep the shell focused and easy to stow
- Regular fit — room to layer for cold, wet conditions
Made in a Fair Trade Certified™ factory, which means the people who made this product earned a premium for their labor, and the 100% recycled polyester shell with a PFAS-free DWR finish reduces reliance on virgin materials and harmful chemistries.
Right pick for cold-weather fly fishing, shoulder-season hikes, and wet, chilly days around town when a plain shell isn't warm enough and a bulky parka is too much.
