Three Night Test
I spent the last three night in the 'Tube'...All three Tarpless
First night- 48 and clear.. cozy...
Second night 46 and very foggy.. I slept well, but woke a 4:30 to pee and found condensation on the inside of the tube.. I wasn't sweaty but the inside of the tube was..as I was wearing sweat shirt and pants it was't a problem. I was able to get right back to sleep...
Third night 46 and clear .. another good night no fog = no condensation
In the future I'll use my DIY Tyvek tarp if Fog is predicted..
Here are my Pix
Dave, thanks so much for the pics! As quoted you said you were wearing sweats, but I was wondering what else you were using? As in a sleeping bag or Quilt??

two answers.... I have a compression sack that i can get to the size of of a Rugby ball and I've been testing a space saver travel bag http://www.amazon.com/Compressible-V...ref=pd_sim_k_3 .
It packs into a space about the a large coffee table book. For me it's about which will fit better into my pack.....
A few more questions...
Whenever you've had condensation inside the tube, where has the dampness been? When I've noticed some it's been at the foot end, underneath my feet. The parts around my body are always bone dry. I was thinking that it may be the warm air cools at this end as it's furthest from a heat source, my body, and so condenses. Since the tube has plenty of room around you the slight damp never comes into contact with anything anyway so is no a problem as it then can be aired out.
It was on the tube over my mid section but not on my body..This has happened once in 25 nights..I live in San Diego and the humidity is very low here....
like i said on the east coast or areas with high humidity your going to have lots of problems with condensation ... this is why you don't see alot of ppl trying to use them
quilts will not have a condensation problems since the breathe and pads are alot easier to regulate for condensation problems
alot of the problem is the lack of airflow ... the tube does not breathe at all
and your breath does not help when you have it closed up around you
and if you have it opened up to breathe all your heat will go out with the wind since there is no where for the hot air to sit like a quilt holds the hot air against you ....
so there is no real way to fix the condensation problems you will have in temps below 32F in the west and most of the year in the east or in areas with high humidity once you see condensation set in your going to have to regulate the airflow...so you will be opening and closing the tube all night long ....
i'm not knocking the idea...i'm just stating facts like i said alot of us have tried this...;) i remember when i first started out with hammocks i couldn't bring myself to spend that much on a UQ .... but they are the best option out there right now ... if you can figure out a way to make this work at all temps without condensation problems that would be cool to see... but i don't see it happening :cool:
that and i don't want to see someone wake up miles from home all wet and cold with no way to get warm...it's just not something you want to happen while on the trail ;)
also have the 2 of ya's tried IX ..... might be worth a try if you are trying to stay warm on the cheap ....
you can get a few yards of it and make an UQ out of it .... would be a $40 UQ that will be alot better when it comes to condensation ...
just some ideas for ya to try ;)
Below 32 in San Diego????? If it is ,there is no way in hell I'm hanging...
I don't need to try anything else because the Tube works for me.
I'm no engineer, but I think because I can't make the holes on the end the same size, I always get a small airflow through the tube, which prevents condensation from building up.
It seems you are taking experiences from other systems and applying them to the Survival Tube that frankly don't apply.....
FYI.. another comfy night in the Tube last night... Low temp 50....
