Technical Specifications
Next-generation insulation technology
The Guide Aerogel Hybrid Vest uses Aerogel—an ultralight material with the highest insulation-to-weight ratio of any solid—to deliver remarkable warmth where it matters most. Strategic Aerogel panels retain their insulating capability even when compressed by a pack or harness, while merino-blend fleece side panels offer stretch, breathability, and efficient moisture transport during intense ascents. A new ultralight Japanese ripstop shell fabric adds wind resistance, weather protection, and mobility without bulk. The sleeveless design frees your arms for climbing, skinning, scrambling, and technical movement, making it an ideal layer for ski touring, alpinism, and variable-temperature days. Lightweight, packable, and cut for unrestricted motion, it’s a specialist core-warmer built for long missions in demanding terrain.
