The men's REI Co-op Swiftland Insulated Running Vest pairs 40 g of recycled synthetic insulation with a close-to-body fit and built-in mechanical stretch, so you can keep running through colder temps without overheating. The body-mapped insulation sits at the front and collar to optimize warmth without bulk.
A durable ripstop nylon shell with a PFAS-free durable water repellent finish helps moisture bead up on the surface, while breathable, water- and wind-resistant ripstop nylon panels at the back, shoulders and sides keep air moving. Five pockets include a zippered chest pocket, zippered hand pockets and stretchy drop-in side pockets; the vest packs down into a side pocket and has reflective details front and back.

Which insulation do you prefer?
Down: Ultralight, warm and packable; loses insulation when damp. Synthetic: Insulates when damp, dries quickly; heavier and less packable than down. Down/synthetic: Warm in targeted spots; warm when wet but heavier than pure down.
Consider these features
Waterproof: Most are water-resistant; choose waterproof for added protection. Ventilation: Pit zips or core vents help release heat during high-exertion activities. Hoods: Some detach or accommodate helmets. 3-in-1 jackets: Outer shell and insulated midlayer zip together; wear separately or as one. Pockets: Stash gear, secure valuables.
