SF Belay Smock 4.0

The fourth generation of the SF Belay has taken our bestselling insulated jacket and refined it with the cold weather warrior in mind.

Using our SDP technology with our new IRR multi-terrain camouflage pattern that also reduces your thermal signature, this system keeps the wearer completely dry and comfortable no matter how long and how hard the downpour. Combined with a Primaloft Gold® insulated filling with a soft touch matrix inner lining, this insulated jacket can handle the harshest of environments.

Nepal Himilayan Expedition – “An extremely durable, light and unbelievably warm jacket”

The Belay Jacket is without doubt on of the best garments produced by Keela. It was perhaps the most versatile, useful and most worn item of Keela clothing worn on the month long expedition. It was worn everyday and it even sufficed as the main outer garment at over 5500m on a remote and chilling glacier. It also proved useful as a night time pillow. On the summit day it was used as part of the mid layer system along with the Summit Top and the Munro Jacket. In complete contrast we wore it travelling to Nepal because it looked smart and was very versatile as a travelling garment. By the end of the expedition the Belay Jacket was in need of a wash but was completely undamaged and showed no signs of the extensive use it received on the expedition. An extremely durable, light and unbelievably warm jacket; even keeping us very comfortable at 550m on a remote and cold Himalayan Glacier. Following a hand wash the Belay Jacket looks as good as new.”
