Draft tubes ?

**howiez3** · 01-30-2009, 16:02

Has any one experimented (or produced ) an Under quilt with draft tubes ? Seen a few threads discussing getting a good fit around the perimeter of the hammock .Wondering out loud if this is a solution ?

Yes, the Warbonnet UQ's have draft tubes at each end, at least the synthetic one I have does, Brandon would have to address whether the Yeti does or not.

The Yetis have big ol fat draft tubes. Nothing gets past them; don't eat Taco Bell!

Geez! I was recently pondering draft tubes in a quilt, although I hadn't come up with that name for them... you guys think of everything!

they're just on the end edges. they seem to do a good job of closing a small gap (like an inch or so). the uq will still need to fit snug in the interior of the uq as well. if it's baggy, it can still lose heat even if it's sealed well around the edges so watch for that too.

Here is a pic of my down Yeti...the draft tubes can be seen on the ends under the shock cord

I had this Yeti at the Mt Rogers hang...you could have inspected it (if we had only knew...)

I was thinking last night about an UQ with draft tubes. I am planning on making an UQ with differential baffles and I can't quite figure out how to get the bathtub shape and have differential baffles like the snugfit does. I have thought about the putting pleats and darts on the top and bottom but coming up with the right dimentions top and bottom is mind blowing. However what if you had a regular differential baffled quilt and then had a draft tube around the perimeter. Kind of like a reverse differential baffle that went around the outside and then put pleats on the corners.I know I am just rambling and noone can see the picture I have in my mind, but a couple weeks from now I will have it done and you can remember it was this dicussion that spurred the draft tube idea.

That Yeti looks mega-sweet, any opinions on a possible low temp with it? What is it's approximate loft?

The discussion thread for the Yeti is here.

My first review is here

I used it at Mt Rogers
night 1 was 28-30*F w/20-25 mph wind...no problems staying warm
night 2 was low of 10*F rising to approx 20*F by daybreak. Had a little cold butt issue but put another layer of insulation at my butt (my hat) and fixed it.

I was using a 30*F sleeping bag as a top quilt, the Yeti, a full length ccf pad (doubled under my legs), and my DIY hammock and I no issues (I had to adjust the suspension of the Yeti to fit my hammock but it was expected) I took a temp reading under my TQ and was reading 82*F

almost too hot!

I'm very happy with the performance, weight and compressibility of the Yeti.

I think draft tubes do a great job of stopping "cold air creep"
