Jackets with synthetic insulation are now the go-to choice for walkers and climbers who need warm mid or outer layers that will work in cold and often damp conditions.
Synthetic Jackets & Pullovers : Jackets designed to provide extra warmth on stances and/or an extra warm mid-layer. Can also be used as general warm jackets for wandering around town in.
Synthetic Vests: Body-warming waistcoats. Very good at providing core warmth for minimal weight and very useful for ice-climbing as they can simply passed from climber to climber depending on who is belaying.
Synthetic Trousers: Synthetic fill overtrousers - great for high altitude base camps.
