The Mountain Equipment Diamir makes you feel completely protected in the worst of British weather. Though slightly on the heavy side at 530g (size UK12), it is very stormproof and amazingly durable, with Gore-Tex Pro Shell Tenacity reinforcements over the shoulders, upper back and upper arms. The rest of the jacket uses highly breathable Gore-Tex Pro Shell Ascendor II fabric, so it feels very comfy when you’re exerting yourself, and you can also open the water-resistant pit zips and glove-friendly cuff adjusters for extra venting. There’s a double stormflap in front of the main zip, and the Napoleon chest pocket and high side pockets (accessible when wearing a hipbelt) have stormflaps as well as the usual water-resistant zips. Even so, Mountain Equipment still includes a warning note to remind you that the pockets are not completely waterproof. There’s also an inner mesh pocket and elasticated pouch. The wired-peak hood is superb – fully adjustable, helmet-compatible and folds away secured by Velcro. The jacket comes up quite large, especially around the arms, so you might need a size smaller than usual, depending on what insulation you usually wear underneath. The closest men’s equivalent is the ME Kongur (£300).
