We see these threads periodically talking about the merits of tarp set-ups, bivvies, hammocks etc. I'd like to start this thread off as a discussion considering the merits of light shelters and considering cost/benefit and performance/convenience factors of different combinations. Where possible, I'd like people to gather hard facts (specs) supporting claims of light weight etc.
Things to consider. Use in rainy conditions, use under windy conditions, four season use. What are accessory items needed for a complete shelter + sleeping and overall weight costs (minus sleeping bag).
Light weight options:
Ultralight tents. Some of these like the big agnes SL1 seedhouse weigh as little as 1.0 kg (2 lbs 13 oz) complete with fly. Advantages: good for buggy conditions, rain and wind. Tents keep condensation off of body. Fly can be used on its own as a tarp. Accessory items required: sleeping mat.
Disadvantages. Price $250.00, only sleeps one although the SL2 is 1.2 kg but costs $320.00 for larger tent. Needs level ground to set up. Set up times vary depending on the tent and practice. Usually at least 10 min.
Overall - I like tents the best for comfort and personal feeling of security (I know that is a false sense but it is what I group up with). However, you often pay for that luxury in price and weight.
Silnylon tarps. Depending on the size, weights can range from 0.4 kg to 0.7 kg. Can be set-up in a variety of ways. Some tarps like the Integral designs sil-shelter are pre-shaped so that you set up with a single pole (like a trecking pole or cut sapling) and stake down. This would make set-up quick and easy. Accessories are more than just the type. It seems to me that some kind of ground sheet is required for foul weather (i.e. prevent rain from leaking on you) which will add perhaps 0.2 to 0.4 kg weight. Also requires sleeping pad (like all shelters) and sleeping bag.
Advantages: perhaps the lightest option even with ground sheet. More space and flexibility in the space provided (i.e. you can set the tarp up higher for greater room). Setting up the tarp higher off the ground eliminates condensation, even better than a tarp. A lot of people like the openness of a tarp. Great view of the sky. Set-up would be really fast, faster than a tent. Price is great - ranging from $10 for a blue tarp (at weight cost) to about $150 for high end, pre-shaped sil-nylon ones. Finally, the biggest advantage is the packability. Smallest packed package of all shelter options.
Disadvantages: Buggy conditions - either just deal with it, use a tonne of bug spray or use a mosquito screen or bug shirt in sleeping bag. Rain + wind can lead to shift in direction of rain fall and get you wet. Like tent, requires level ground to set-up and sleep under. The designs that use a pole on the inside (like the Sil-shelter) - you have to avoid knocking out the pole when having a "practical-tactical" dream.
Bivy Sacks
The ultimate in single person shelter. A tiny single walled tent that essentially fits around your sleeping bag. Some are more elaborate than others with a small pool that lifts the face portion of the bivvy up and keeps it off your head. Some zip right up for full enclosure, other more basic ones keep the face open or have no-seeum mesh at the face but require a small tarp to keep rain off the head portion. Full water proof construction at bottom of bag and top part of main body. Price varies tremondously, from $30 for the AMK (not waterproof and emergency usage) to >$300 for full gortex + pole designs.
Advantages. Simplest set-up of all. Lay-it down, place sleeping pad and bag inside and get in. Four-season application. As indicated above, some require a small tarp be placed over the face area for additional rain protection. Weight seems intermediate between tent and tarp. More elaborate systems weight 1.2 kg and lighter ones can be had at 0.4 kg.
Disadvantges. Claustrophic people need not apply. Probably the worst sense of security. Sitting in the open, while at the same time quite immobilized by two layers of sleeping bag and surrounding bag and all those zippers (again I'm projecting my phobias onto the discussion). Condensation is the biggest issue. The close proximity and often lack of breathability causes the condensation to form right at the outer surface touching your bag.
Hammocks
Okay - I don't have much experience on hammocks and I have to go to work now, so hopefully somebody else can continue the discussion on hammocks.
