Bivy Sacks
If you wish to stay ultra light in your backpacking trip, you might prefer considering alternatives of backpacking tents as such. Bivy sacks serve good for the purpose not only in terms of weight but also in terms of cutting down on the time needed to peg a tent. Though these sacks are small in size yet they are big enough to hold a sleeping bag and a pad. If you don't mind sleeping in a covered pack, Bivy shelters are all for you!
