I just purchased the Henry Shire's Tarptent Squall 2 without the sewn-in floor. From what I've read, the Tyvek ground sheet that they sell on the site is overkill (heavy), though at 7.5 oz, it's not much more than the additional 7 oz of the sewn-in extended floor option.
Regardless, I'd like to get other recommendations.
Is the 2-mil plastic that they suggest on the site adequate?
Anybody know what the 5.5 oz option used in the BPL review of the tarptents was?
Would sil-nylon work? It seems to be what they use on the Squall.
I was hoping to get a Thermo-Lite All-Weather Survival Blanket as mentioned here, but it seems to have been discontinued.
What about one of those foil-like emergency blankets? I'm assuming those would be too noisy and I'm not sure about the durability.
