As part of Sea to Summit's online Sleep System (see the review here), the sleeping liner that was recommended for our gear writer Caro Ryan was the Sea to Summit Thermolite Reactor Compact Plus (short).
"Up to this point, my Sea to Summit online personal shopper had played its cards straight out of Indiana Jones and the Holy Grail and ‘chosen wisely’. So when I saw that the liner had been supplied as size short, I was surprised… and not for the first time.
Turns out this liner only comes in one size that they describe as being, ‘ideal for women and youth’ and ‘for gram counters under 6 feet tall’.
Thermolite – a fabric designed for lightweight warmth – is made by the people behind other technical materials such as Lycra and Coolmax. This isn’t the first time I’ve used a S2S Thermolite Reactor liner.
I like the benefits of adding warmth to a sleeping bag, whilst also keeping all my dirt and sweat to myself, rather than sharing it with my sleeping bag. Let’s face it, cleaning bags is a pain and a liner can help minimise the need for regular cleaning.
When it came to getting into bed, I discovered the benefit of using a smaller liner with a larger sleeping bag. With the shorter liner, I was able to use its cinch cord to draw the bag over my shoulders, which felt like a warm hug. Nice."
