Rab Ascent Silk Liner: first impressions
The Rab Ascent Silk Liner tips the scales at just 130g/4.6oz, so it will suit even the most weight-wary backpacker, as well as working for travelling and traditional camping adventures.
A natural substance, silk is a bit of a wonder material for liners, as it traps in heat quickly but still breathes well and has a great warmth-to-weight ratio. It feels pleasingly soft against the skin and even has antimicrobial properties, so it’ll help keep your best sleeping bag fresh for longer as well as protecting its inner material from dirt and oils.
This quality liner should last for years with care, and Rab also offer a repair service that extends the life of your kit, which is a more sustainable option than having to splash out on a new one. Despite the price tag, this is definitely one of the best sleeping bag liners, and well worth investing in if you love sleeping in the wild in all seasons.

Rab Ascent Silk Liner: in the field
Of all the sleeping bag liners we tested, this was the most versatile, keeping us comfortable on both warm and chilly nights, and trapping in body heat fast, making drifting off to sleep easier on bitter spring nights.
We also liked the hood, which sits snugly inside the top of a sleeping bag and stays put, but it won’t hold a small camping pillow in place like some liners with pillow-specific pockets can.
Rab reckon this liner is mummy-shaped, but on test we found that this tapered bag sat somewhere in between rectangular and mummy shapes. It is a good choice if you want just one liner to fit into all your sleeping bags without having too much extra material bunched up in any design you choose to pair it with.
