Ultralight, warm, windproof and water-repellent – makes for happy outerwear. A large, thick Moncler style coat is a welcome addition to any man’s wardrobe but if you want something a little more versatile and mobile, Patagonia is it.

The Patagonia down jackets are touted as suitable for brisk mornings and evenings in the Canadian Rockies or High Sierra but they’re equally at home in less exotic climbs.

The Patagonia Ultralight Down Jacket is great for slipping on or packing away in your rucksack, just in case the temperature drops. Made with a polyester ripstop shell with a Deluge® DWR (durable water repellent) finish, tear-resistant material and top-quality 800-fill-power premium European goose down. Best of all it weighs in at just 235g and comes in a slim fit.
