"What Our Gearhead® Experts Are Saying:""I throw the Rime Air IN Hybrid Vest on when I want to stay warm but don’t want to overheat. It breathes super well and stretches with me on the move. I love that it packs into its own pocket—perfect for fast missions with changing temps.""We reach for the Rime Air IN Hybrid Vest when we need just the right amount of warmth without sacrificing mobility. Built by Mammut with lightweight polyamide and Mammut’s proprietary LoopInsulation, it’s a versatile midlayer or outer piece ideal for active mountain pursuits. Stretch panels increase freedom of movement while regulating temperature on the move. The PFC-free DWR finish adds wind and water resistance for changing alpine weather, and the athletic cut stays close without restriction. Two side zip pockets keep essentials accessible with a pack on, and when the sun comes out, it all packs into its own pocket. This vest is built to adapt—just like we do in the mountains."
