Montane Prism (2013)

Long a stalwart of good kit and prices, Montane’s Prism is another example of kit purpose-built for the UK. Insulation is Primaloft Eco, which – while not as soft or thick as Premium Primaloft One – uses 50 per cent recycled fibres. It’s still good, warm and adds a pleasing earthy tick, and a weather-resistant Pertex Microlight outer offers further value. Two high-set pockets take an OS map and also serve as a pack-pouch, while other features include Scotchguard reflective decals, an excellent hood with a wired peak and a chinguard, and a robust stormflap behind the zip. A few elements let the Prism slip: the cuffs are of the chafey elasticated variety, so they can be pushed up the arms to aid venting, but they are aggressively elasticated (I found them too tight) and aren’t adjustable. The pocket zips have tabs to pull on, but the main zip tab is small and difficult to wrangle with gloves. Fit balances baggy and slim nicely, which means it works as either an over layer or a mid layer; but those tight sleeves are also quite short, which restricted my movement a little. But if the Montane Prism fits and is comfortable, it offers unbeatable value.
