Year round mountain insulation

A modern classic, the Prism Jacket is an insulated jacket that’s been a firm favourite since 2008. There have been many iterations as the design team have continued to improve fit and introduce technical refinements. The current version uses weather resistant PERTEX® QUANTUM, 100% recycled 40g/m2 PrimaLoft® Silver insulation and upgraded with a lightweight nylon lining; the Prism Insulated Jacket has a climbing helmet hood and multiple pocket options. It packs down into its hand pocket so it’s small enough to be kept in your pack for a warm, windproof weather resistant layer that’s ready for almost any weather change. The water repellent insulation is lightweight and quick drying, keeping you warm even in wet conditions.

Designed to keep you warm, even when wet

Warm, lightweight, highly packable and 100% recycled, PrimaLoft® Silver insulation is water resistant and provides excellent thermal efficiency, ensuring you stay warm even in wet conditions.

Designed to provide high levels of warmth with minimal bulk, the insulation provides an excellent warmth-to-weight ratio while also being highly compressible, allowing it to pack down small.

The ultra-fine fibers of the PrimaLoft® insulation trap body heat, keep out cold air and provides a very tight surface tension to keep water at bay. Treated with a permanent water repellent finish the insulation is hydrophobic, repelling water and moisture. This ensures the insulation continues to keep you warm when wet and is very fast drying, perfect for unpredictable weather.

Windproof and water repellent weather protection

Windproof, water repellent and soft to the touch, PERTEX® QUANTUM is constructed in a tightly woven structure to provide windproof protection and trap still air inside the insulated jacket. This allows the PrimaLoft® insulation to fully loft and retain its warmth.

The fabric is lightweight, packable and soft to the touch. A durable water repellent (DWR) finish allows the fabric to shed light rain and snow, allowing the jacket to provide weather protection in adverse conditions.

The fabric is constructed using highly abrasion resistant nylon ripstop, incorporating reinforcement yarns to provide durable resistance to tearing, helping the fabric to withstand harsh mountain environments.
