Reflectix for tent floor comfort?

Others have used it for a sleeping pad or under a second pad. I am not sure I have seen it to cover an entire tent floor.

This is; or at least it was; standard practice here in Oz but rather than reflectix it is 3mm EVA foam.

I am using scraps of floating floor underlay. Lots of it leftover from renovations  If you use it under the tent floor you don’t need a footprint, it does add a little warmth tho and if you have the space I would use it inside and out

“Anyone ever try this?  Figured I’d try it both ways – below the floor outside the tent, sort of like a footprint.  And inside the tent.  I think outside may be best to reduce any condensation between it and the tent floor when inside?”

I, too, use it all the time, but only when car camping or going short distances.

I also only use it underneath my tent, so it can double as protection for the floor. This is especially good while camping with kids & dogs.

I have found that the mylar film will peel off unexpectedly and “stick” to the underside of the tent on occasion. But given what it is, I’m fine with that happening.

“Most brands of foil-faced bubble wrap are only 3/8 inch thick or less, and have an R-value of only 1.0 or 1.1.”

The hype.

Hmmmm… Ed, good idea on using underlayment foam for a “ground cloth” under a tent floor. I think Relfetex is too fragile for backpacking and it’s bulky as heck.

I have a mummy shaped piece cut to for under my Thermarest Prolite pad for shoulder season weather below freezing.

Since I have a half roll left I think I’ll curt a floor-shaped piece for winter camping. I’ll have to roll it up and strap it under my pack but compressed snow, the underlayment piece and my Thermarest Trail Pro should take me to at least -15 F. with my -20 F. down sleeping bag.
