What Our Gearhead® Experts Are Saying:"I stuffed this into my pack for a shoulder-season hike and ended up wearing it most of the day. It’s lightweight but still holds heat well, and I like how small it packs down when I don’t need it."Cool mornings and shifting conditions call for layers we can trust, and the Claude Jacket from Halfdays is built for exactly that kind of day. We bring it along for early trail starts, breezy ridge walks, and everyday outings where lightweight warmth makes all the difference without weighing us down. Packed with PrimaLoft® insulation and wrapped in a recycled ripstop shell, it balances warmth, breathability, and durability. The water-repellent finish helps shed light moisture, while the adjustable hood and hem seal in heat when temperatures dip. When the day warms up, it packs into its own pocket, making it easy to stash and carry without taking up space.
