Patagonia M's Insulated Boulder Fork Rain Jacket

Waterproof Insulated Rain Jacket for Cold, Wet Conditions

The Patagonia M's Insulated Boulder Fork Rain Jacket is built for cold, wet days when staying dry is only part of the job. Lightly insulated with 40-g Thermogreen® 100% recycled polyester, this stormproof jacket adds breathable warmth for winter bouldering, early season trout fishing, travel, and everyday weather protection.

H2No® Waterproof Protection with Recycled Insulation

The 3-layer H2No® Performance Standard shell delivers waterproof, breathable protection with long-term durability in rough weather. A light, air-permeable stretch ripstop lining and 40-g Thermogreen® insulation provide low-bulk warmth, while the fabric, membrane, and DWR finish are made without intentionally added PFAS.

Packable Features with Fishing-Friendly Storage

Streamlined details keep the jacket focused and packable. A low-profile hood with laminated visor and single-pull adjustment sheds water and maintains visibility in poor conditions, while the waterproof center-front zipper, chest pockets, and high handwarmer pockets provide functional storage for fly boxes, maps, notebooks, and daily essentials.
