Read: How to choose an insulated jacket / Your guide to the layering system
For ultimate warmth-to-weight and packability in cold, dry conditions, nothing surpasses the efficiency of a men's down jacket. Its high-loft clusters create a thermal barrier that is incredibly light and compressible. For UK use, look for models with hydrophobic down, which resists moisture and maintains performance.
For uncompromising reliability in cold environments, a men's synthetic jacket is the superior choice. Advanced synthetic fills like PrimaLoft jackets for men are engineered to retain their insulating structure even when wet, making them ideal for strenuous, stop-start activities.
Our range, featuring expert brands like Rab, includes everything from a lightweight insulated coat for active layering to thick parkas for static warmth. Whether you prioritise the raw thermal efficiency of down or the wet-weather dependability of synthetic, you will find the perfect technical solution for your next cold-weather adventure.
