These Sea to Summit Capped Compressions Sacks are super light as they are constructed using Sea to Summit Ultra-Sil™ fabric - a 30 denier siliconised fabric with hard wearing Cordura caps to produce a light but tough compression sack.
These compression sacks also have the ability to compress the contents down to a third of the original volume - for example something that started as 15 litres can be compressed down to 5 litres.
To keep the Ultra-Sil compression sack to a super light weight they have also trimmed down the webbing and buckles and made the sack more user friendly with a unique cap construction.
Additional features include reinforced stress points; special cap construction to prevent tangles; four sizes and colour options available.
Apart from sleeping bags, these sacks can be used for anything from a down jacket, clean clothing, laundry, tent flysheets, etc.
