Have ya tried it out ?? You have the icon right ?? I think its really going to depend on what pack ya have an also what other gear....those guys on bpl have pretty minimal stuff with them since there just hiking..
Il tell ya its not to big of diference an if im feeling lazy an heading back to the truck i wont worry bout the stuff sack...just cram it all in an go...I dont have big heavy items like alot of people have been saying tho that need to be on a shelf

not sure whats they're referring to, food maybe
Might aswell give it a shot an see how it works with you/your gear
