The Podsacs Spider Compression Sacks are an ideal solution for space management on the trail.  They neatly compress items such as sleeping bags or bulky clothing. 

These lightweight but durable bags feature a round base design with 4 compression straps for even compression and added strength.   Side relaease buckles get you packed and unpacked faster and with greater ease.

Stated sizes are fully expanded.  When anticipating what sack size you will need, choose the size that most closely matches the normal uncompressed pack size of your item. 

* * Reasonable expectations and good judgment should be used with all compression sacks.  It is possible that an individual can exert sufficient force to tear the bags as would be the case with most fabric items.  Best practice is to compress sacks from the end by hand then tighten straps to snug. * *
