I had a thought while reading a thread about the Rainbow vrs Double Rainbow, but didn't want to hijack that thread....

Years ago when my kids were preschoolers and I took them camping, I made a little pup tent for them inside my monsterous family cabin tent. The reason: there were no real sleeping bags for babies available (mne sleep in a bunting bag up to age 2-3) and children's bags were limited to the 'slumber bags' found today with Barbie, Barney, etc printed on them (temp rating about 55 F). The wee pup tent kept my babies warm.

So, I was thinking that this idea might have some application for those of use who design our own sleep / shelter systems. While I know Shires has a shaped liner that clips onto the tent interior on the Rainbow 2, I'm picturing something more like the top portion of a bivy -- on steroids.

Has anyone tried something like this?

I have thought about this also. I recently made a Ray-WAY Tarp. I will be making a RW net tent this spring before bug season. To sleep warmer in the Winter, could I use the net tent pattern but instead of using no-seeum mesh all around, use silnylon around the sides? Would condensation be a problem?

Don't use it any more but still have a mat (mylar on one side and vinyl on the other) that fits perfectly on the floor of our old Sierra Designs and REI Half Dome tents. It acts as a pretty good vapor barrier. We keep it in the gear locker for those rare "car camping" trips where weight and the amount of gear we carry isn't an issue.

When you're done... isn't the net result.. just a double-walled tent?

Would condensation be a problem?I did something like this for a friend a while back to go under his tarp - the lower 1/3 of the wall is silnylon, the rest is uncoated nylon - he says he has no condensation issues with it and it adds about 10 degree F to his set-up.When you're done... isn't the net result.. just a double-walled tent?Yes and no -- it can be left at home when not needed and it could double as a windblock outside the tent without compromising the waterproofness of the tent. On most double-wall tents, the detachable wall is the rainfly....

Back in the 70's, I remember Eddie Bauer used to sell real equiptment, more so than just clothing, and they had a 4 season tent that had an inner fly to catch condensation to prevent dampness from falling unto your goose down bag. Sounded reasonable to me. Never had the opportunity to try it out, but in theory, possible.

Long long ago in a faraway land called real wintertime, we used to have tents with removeable Frost Liners. I can't believe that someone doesn't still manufacture them. My original was WWII war surplus US Ski Troop issue. Actually, my ski poles, skis, and boots were too. Whoops, now I am forgetting about the dingy white parka and pants. Back in the late forties and early fifties many of us kids could be spotted wearing old 10th Mtn Division surplus gear that old fathers and uncles brought back from the war.
