The Rab Khroma Kinetic Bib (Women’s) is a technical waterproof shell bib designed for ski touring, mountaineering, and alpine backcountry use. It’s engineered around Rab’s Proflex™ three-layer stretch-woven fabric, which blends the protective traits of a traditional hardshell with the comfort, stretch, and mobility of a softshell — a combination that supports dynamic movement on steep ascents and descents without sacrificing weather resistance. This bib is cut for mountain skiing and expedition use, with articulated knees and a stretchy lower back panel that promote a full range of motion on kick turns, traverses, and bootpacks. The high bib suspender structure helps keep snow out while also providing space for layering without bulk, and the regular fit accommodates insulated base layers and midlayers beneath for colder conditions. Rab integrates practical details that enhance comfort and functionality during extended outings. Large zippered thigh vents help release heat efficiently during uphill climbs, while multiple ski-specific pockets — including thigh and rear pockets and a high bib pocket — give riders secure storage for small essentials and tools on the go. A drop-seat feature adds convenience for quick breaks without removing the bib. Durability and field-ready design are evident in features such as reinforced cuffs and internal gaiters that seal out snow and protect against abrasion from boots and crampons. The Proflex™ material’s breathable membrane and PFC-free durable water repellent finish help manage moisture and weather on long spring missions and changing alpine conditions. Overall, the Women’s Rab Khroma Kinetic Bib balances weather protection, stretch, and breathability for ski tourers and mountaineers who demand mobility and shelter from wet, windy mountain conditions without excess bulk.
