Rohan’s synthetic insulated jacket offering is lightweight, quite breathable and comfortable. It’s my first choice of the three synthetic jackets tested. It has thinner insulation in the sleeves, which helps keep the weight down and stops the arms overheating. I’ve worn it all day on very cold, very windy days in the Cairngorms and stayed warm. I haven’t overheated when sheltered from the wind either. The design is fairly standard with a few neat features. The inner pockets are made from stretch mesh and are very roomy, making them excellent for storing hats and gloves to keep them warm. The collar and lower pockets are fleece-lined for comfort. As with many garments the lower pockets are just accessible when wearing a hipbelt though the bottoms are cut off. There’s no hood but the high collar is snug and warm. The large size is very roomy – I can easily wear it over a thick fleece.
