What Our Gearhead(R) Experts Are Saying: "I use this as a go-to midlayer for touring and cold lift rides. It packs down small, warms up fast when you stop, and the merino insulation stays comfortable even if things get damp."When we're moving uphill or chasing changing conditions, we need insulation that works with our pace instead of against it. The Arete Merino Insulation Hooded Jacket from Mons Royale is built for active mountain days, offering lightweight warmth that layers easily under a shell and stashes away when output climbs. Merino wool insulation regulates temperature naturally, keeping us warm during transitions and comfortable when effort ramps up. Stretch merino fleece side panels improve mobility and breathability, while the recycled Pertex Quantum shell adds wind resistance and light weather protection. With a streamlined fit, zippered pockets, and a soft, packable feel, this jacket becomes an easy layer to rely on when conditions demand adaptability.
