Stretch fabrics mean the Berghaus Affine can be close-fitting without being restrictive or uncomfortable, which is good as the sizing is on the small side, the Large just fitting me over a base layer. The jacket is warm enough that I doubt I’d ever need to wear it over anything more, at least not in the UK. The Hydroloft fill is soft and lofts well.

The Affine has a good adjustable hood with a small, stiffened peak. The handwarmer pockets do sit under a hipbelt but are just about usable. I like the inner stash pockets too as these are roomy and set well above a hipbelt. They’re great for stuffing damp gloves in so they can dry out or stay warm.

I used the Berghaus Affine on many winter days and it proved warm, breathable and comfy. I didn’t wear it for long when walking – it’s too warm – but it was good for stops and camps. The shell fabric is wind-resistant but not windproof. In very strong winds a shell is needed over it.

The Affine is quite expensive and it isn’t that light, but the hood and the stretch fabric make it worth considering.
