Sea to Summit Ultra-Sil™ Compression Sack

When you need to compress your bulky gear without significantly adding
weight, our Ultra-Sil™ Compression Sacks are the perfect choice. Made from
high-strength 30D siliconised CORDURA® fabric they can be compressed
to one third of the original volume. Ideal for use inside your pack or travel
bag when you need to compress clothing or bulky soft items to allow space
for other essentials—or luxuries. The size range includes two extra small
options good for compressing and storing down jackets and other clothing.
