both me and my mate have the 2 man force 8. fromthe time its out of the bag to being pegged down is really within 30 seconds, done a night in it last week when the temperture was -3 and had no problems concerning the cold (of course sleeping bag and layers helped) i like the fact the groundsheet is part of the bivvy so you have 100% confidence that is pretty dam hard for rats to get in (unless they wanna chew through the bivvy) putting it away is the worst part for me anyway. comes down easy enough but to be able to wrap it all up small enough to get the straps back round it and get it back in the bag it takes 2 of us lol. could be done alone but easier when you have a mate there to help compact it down. all round nice bivvy
