Featuring a large 30 litre capacity, this compression sack by Eurohike is fully waterproof and a must for those large, bulky items that take up room when off on holiday or travelling. This fully waterproof sack compresses soft items, from thick jumpers to pillows, and is essential for travellers wanting that extra room when on the move. This compression sack includes a roll-out feature which works by removing the excess air and making the sack completely airtight. With a Velcro closure for that extra tight seal, this compression pack is ideal to take with you wherever you are heading.
