The Pertex Microlight Rip-Stop outer layer is windproof and water resistant giving excellent weather protection, it will comfortably keep snow at bay and will resist light rain too.
Primaloft Eco is one of the top synthetic insulators and unlike down, even when completely wet will retain much of its insulating properties, perfect to the changable UK conditions!
