The R1 takes an unusual approach by having its fleece fabric on the inside and a smooth, stretchy microfibre face-fabric on the outside. The internal fleece material is called Regulator, and it is soft, extremely light and surprisingly warm. This is in part due to an insulating grid pattern which keeps heat close to your body while still retaining breathability and wicking away moisture. On cool days, or when your walk demands serious exertion, it allows you to move easily and freely and keeps comfort levels high. The smooth face fabric is designed to be quick-drying (but not actually water-resistant) and also makes it easier to throw on an outer layer – the thickness and fluffiness of fleece can sometimes make it hard to do that. Sadly it has no pockets (not even a chest zip), but this is an excellent top if you’re a pacy walker or like your ventures with a hefty dose of ascent.

Great by itself on mild days and good for layering in deep cold.
