Frequently, gear that promises to bridge the gap between technical and casual ends up compromising, so it doesn't work particularly well, look all that great, or both. Maloja's managed to hit the sweet spot with the ClauM. Jacket, a techy and casual piece that's half fleece, half lightweight puffy, and totally excellent. Around the torso, the ClauM. employs Superfine nylon, a smooth, tightly woven fabric that's light, packable, and treated with a water resistant finish. It's packed with PrimaLoft Silver 60 synthetic insulation, which will keep you warm even if it gets soggy and packs down for easy transport. The sleeves, hem, hood, and lining are made from Technostretch fleece, an extremely soft and flexible fabric that feels great against skin and allows for virtually unrestricted mobility and breathability, making the ClauM. an excellent choice for aerobic activities like hiking, cycling, and climbing. A semi autolocking zipper stays in place wherever you leave it, so you can increase or decrease ventilation, and thumb loops at the cuffs keep your sleeves in place when you're moving. The hood and collar both adjust easily with the pull of a drawcord, and two zippered front pockets keep snacks and other small gear within easy reach whether you're adventuring on foot or on your bike. All the ClauM.'s material is also Bluesign approved, meaning it's produced safely and sustainably with an eye on supreme functionality.
