Awhile back I posted an idea for a sketchy pop-up shelter I originally saw on Shark Tank. It seemed somewhat promising but it was ultimately a failure b/c all of the plastic windows shattered once it got down to ~10 degrees.
In any case, I have spent the past month rebuilding this dang thing stitch-by-stitch using my handy Speedy Stitcher and adding new features every time I go out.
It is now a ridiculously over-engineered and battle-tested piece of gear that includes:
* 2 or 3-ply insulation throughout using high-end ripstop+pvc coated tarp
* 1 full half-dome front window using marine grade vinyl rated to -20
* 1 full-length mesh gear pouch plus 1/2 gear pouch on both sides, full-size gear loft on top
* front porch light with 90 degree rotating LED flood light
* integrated half-dome LED lighting with full-length diffuser
* built-in holder with multi-angle adjustable straps for small Mr. Heater
* rear coat hanger
* 8 re-enforced anchor tie downs (top/bottom)
* full width tri-fold flooring with high-density EVA foam
* magnetic door holders with 6 different positioning options
With my back vent partially open and the door mostly open I clocked the internal temp at chest-high at a steady 75 degrees (outdoor temp of 10 degrees.) With the door at ~80 percent closed but still fishable, it got up to a ridiculous 105 degrees within minutes.
It still weighs less than 8 pounds, and I can set it up or take it down in less than 30 seconds.
It also still fits in its original bag at 21″ diameter, and drops neatly in my small sled. Overall, it took way more work than I anticipated but it was 100% worth the effort so far and it has been a rewarding project.
Next big test is high-winds; so far it has never gotten above 12 mph here, and I haven’t even need to anchor it once I drop my duffel inside.
