One of Patagonia’s best-selling products, this fleece mid layer makes use of an extremely open-knit fabric, which helps to keep the weight down by maximising warmth and breathability. The cut is fairly loose and comfortable, with shoulder seams set forward for extra comfort under packs. You get two map-sized hip pockets and one chest pocket. The fluffy finish adds style, making this great on and off the hill. Patagonia is also the most ethical outdoor brand in the UK, which gives this the edge over many similar products. But that open-knit fabric is not as wind-resistant as other materials, so you’ll need a soft shell or windproof worn over the top more often than with some others. The hip pocket access is easily obscured by rucksack belts too, which is a major drawback. There is no hem, collar or cuff adjustment either.
