The most obvious thing is an emergency blanket. It will add a lot of extra insulation per gram. It'a good to have one in you bag on any trip. However, a mere blanket is definitely not enough for all seasons, elevations and weather conditions. When planning at home, you should ask yourself a question: "What will happen to me if I have to be on the route ...

I would say... never. What is a tarp but something that keeps precipitation off of you. In humid summer months, sure, condensation can cause precipitation under the tarp, but in winter, this is not so much a concern, and you can pitch it lower to the ground. You might get frost inside - but just shake it off when you pack up. Tents provide a few degrees ...

A poor tarp pitch can lead itself to condensation. Did you use a plastic ground sheet? Water running under the tarp when it's raining can cause a lot of humidity inside the tarp. Were you pitched on long grass? Plant life can increase condensation under a tarp. This can also be alleviated by a plastic ground sheet. How close to the ground was your tarp ...

I always take a fist-sized SOL emergency bivy bag and a couple of strong black garbage bags. That way you can stuff food and even your body in the bags when conditions are cold and wet. I have also converted a garbage bag into a spare insulating clothing layer by tearing holes for arms and legs. Essential for climbers are a whistle for signalling and a ...

First, consider if you have the right backpack. If you're considering chopping off all sorts of parts, you might be using a pack that isn't designed for you. You could sell it off and buy a more minimalist pack, such as one from GoLite (I say GoLite because I'm unfamiliar with other lightweight packs). With that out of the way, consider what you want to use ...

There are a few common measures that I've seen: Full Skin Out - we're talking everything you're wearing, everything in your pack, food, water, fuel Base Weight - everything in your pack, minus "consumables" like food, water, fuel Worn Weight - stuff on you, like clothes, shoes, hiking poles, whistle around your neck, etc

Down is the lightest and most compressible delivering the best warmth. Down is the undercoating of water fowl. It provides the greatest amount of dead air space of any insulation material for its weight. A down pod consists of light, fluffy filaments that grow from one quill or point. These filaments intertwine and mesh, forming air pockets which trap air. ...

Your most practical solution would seem to be a wing shelter. For the most part, you simply need your tarp, a tree, sticks and rope. The pdf I attached recommends making it 5 feet tall, but you could easily make it 2 or 3 feet tall to accommodate the length you need the shelter to be.

Gelled alcohol has problems even in its "native" setting of a Sterno can. Gelled alcohol burns at a lower temperature. A standard Sterno can take 20 minutes or longer to boil water and is typically more expensive than liquid alcohol fuel. Some good information on different fuel sources for alcohol stoves. Information on Sterno.

The most pressing points are good ground insulation(mat to lie down on) wind protection and then dry clothes. We lose 80% of body heat through the ground. Evaporation of sweat or humid clothes cool at an extremely fast rate too. The amount of heat transfer depends on the evaporation rate, however for each kilogram of water vaporized 2,257 kJ of energy are ...

I used to sleep some times in the Belgium Ardennes which have a very mild climate. For size, weight and especially cost reasons I used agricultural black plastic (don't know the official English term). I used it like a tent replacement; I had a simple sleeping bag but in case of emergency it can be used also as replacement for that (depending on the ...

I don't get condensation under my tarp, not in general, even after several hours in a heavy downpour. I don't pitch it over vegetation, in general. I did have condensation one time when I had it pitched close to the ground, just enough for me to lie under, and it rained heavy all night, perhaps 1-1/2 inches or more. If the rain's coming straight down, I ...

Cuben fiber is not as durable as some other materials used in the construction of backpacking gear. In backpacking lighter often means less durable which is generally true for cuben fiber as well. A cuben fiber backpack will probably hold for 2000 miles (e.g, a thru-hike) but not much more. For this reason, there is now a hybrid cuben/nylon material which is ...

Tenting with two people always comes down to a few items. How easy is it to get in/out? Is there enough room to fit both people and gear? How much does this thing weigh? Can we afford it? You've ruled out the cost. Given that all three tents have two doors, getting in and out should be equivalent. So it comes down to balancing weight vs. space. The ...

These three tents are very similar; freestanding, double-wall dome construction. The limelight is a bit heavier with more floor space. The trail light does not have a transversal pole. Any of them should do just fine. I used a similar tent, the MSR Hubba Hubba, for a while and was quite satisfied with the design. I now retired the Hubba Hubba in preference ...

Although I agree with AM_Hawk as down being both light and compressible, I'd also suggest layering your clothing. Trapping heat between layers keeps warm air near your body, even without using a specific material. The first layer is packed tight next to your body and regulates moisture / sweat: It keeps you dry. For example, a tight t-shirt. Next, a layer ...

I would use a simple emergency bivy bag, a butt-pad (short sleeping pad) (termarest, exped), some extra socks, buff and then you can sleep in all your clothes on the pad in this bag. this should work for emergency, it's not the best comfort but it works in 3 season conditions. For more comfort you can use a light silk liner in your bivy bag. all this ...

This happened to me too - once we took a plastic tarp with us instead of a tent. Terrible storm catched us. But we sweated under the plastic tarp so horrible that we preferred to stay out on the rain and kept only our bags under it. Condensation occurs when humidity meets cold - where humidity is so high (or the temperature is so low) that it cannot remain ...

The key differentiator between tarps and more modern tent material is the breathability and wicking you get from modern materials. Modern tents are very effective at passing moisture outside, but even then, you still see the recommendation that you don't let anything touch the inside of the tent during the night as moisture will take the easiest route. ...

Builders typically get Tyvek in 9' rolls instead of 4' and 5' sheets. You may be able to buy a small piece off of the roll from your local building supply store or find some waste at a local construction site so that you don't have any seams to join. If you do need to join two sheets of Tyvek, Tyvek Tape is specifically designed for sealing the joints when ...

Let's look at the physics behind where all the condensation came from. At night the air gets colder, but the ground has a lot of "thermal mass", so stays much closer to the average day/night temperature. This means at night the moisture from the ground will be entering the air at the ground, but that air will cool as it rises. That increases the water ...

I think anaheim brought up a lot of good points, but I would choose a super light biwi bag that is able to keep you dry whether the humidity comes from the inside (sweat) or the outside (rain). If I take an insulation mat with me depends on existing possibilities to use it. If there are no pedestals you can lay or sit on, I would leave it at home.

OK, I finally tried the setup inspired by this site, which can be fully closed by pegging the sides closer to the middle, and pegging it directly on the ground on the opposite side of the entrance. It would be quite a tight night and you would need to leave your rucksack out, if it's big. But I was able to put the sleeping bag out of the bag from the ...

I narrowed the choices down on a few factors: 1) I wanted to spend under $400 for the tent since my wife and I will only use it a handful of times a year. I don't mind buying a nice tent if it's an older model and purchased off season. Perhaps that's way my fashion sense is always a year behind? 2) I was willing to trade weight for a bit of comfort and ...

This does not answer your direct question in the sense that it does not prevent condensation (so please bear with me), but.. ..a lightweight bivy with a water resistant and very breathable (rather than waterproof) top fabric on top of a groundsheet will protect your sleeping bag from the outside and add a bit of warmth. These weigh from 100-200g upwards, ...

If it's an open top cat stove (or any open top container) you can use gel. If it's a trangia style stove with tiny vents - no. Well, yes you can - the gel will still burn out of the trangia fill hole but it will clog up the vents.
