so basically most compression sacks squash your gear down into a grapefruit shape, whilst its good that a bag is so compressed, the shape is invonvenient and makes for hard packing
as you can see this aint very good for packing in a bag
but, there is a different type of compression sack available
which compresses around the circumference rather than longitudinally, making it alot better to pack in your bag...personally i've used stuff sacks and found them to work fine but to just make grapefruits, so i find this new type of stuff sack really interesting and ill definately be trying to get one when i gather some money together
hope you guys like it as much as i do
