Pick the weight for your season

One bag, three versions, so you buy for the nights you actually face. The 800g is a summer bag with a maker's comfort mark near 12°C, the 1600g handles spring and autumn around 6°C, and the 2000g pushes into the cold at roughly 1°C comfort. Each has an extreme figure well below that, but treat the extreme as a survival number rather than a comfortable night. Choose by the comfort rating and the season and you avoid the classic mistake of freezing in an optimistic bag.

Synthetic warmth that suits damp trips

The synthetic fibre fill is the sensible choice for wet British trekking, since it keeps insulating when it picks up moisture and dries faster than down. The hard-wearing nylon shell handles rough ground and the 210 x 73 cm cut suits most builds, while the full-length zip lets you open the bag flat as a blanket on warm nights or zip it tight when the temperature drops. Available in Brown, White or Blue, it packs down into the included sack.
