Is the $22 version strong enough to stand up to repeated use as a groundsheet? I'm on the backorder list too, but I'm wondering if this will be tougher than the "
heavy duty space blanket" I'm currently using as a ground sheet.
Right now, I'm carrying a 5x8 ID Silponcho, the heavy duty space blanket linked above, and an AMK emergency bivy sack in my daypack. The space blanket is usually strapped to the bottom of my pack for quick access and gets used as a groundsheet or quick shade often. It's pretty robust and has held up quite well with constant use. The Silponcho is for raingear and pack-cover or emergency overhead coverage. The bivy sack would get used in emergencies and unplanned nights out.
My thinking has always been that if the weather turns or is going to turn nasty, and I have to spend a night or two out, I'd use the bivy under the silponcho (pitched in a low and tight a-frame). The bivy should provide me protection against wind-driven rain under the pitched silponcho. The space blanket either gets used under me as further protection from the ground and on top of natural insulation (while providing a little IR reflection), or it gets used to provide further coverage for gear or to extend the coverage of the silponcho. If this Survival Tarp can stand up to use as a groundsheet, I might as well replace the heavy duty space blanket, since this tarp has tabs (better for quick shade pitches) and is a bit lighter and easier to pack away.
I'm constantly changing my shelter setup. Lately, I've been toying with the idea of carrying my 8x10 Siltarp (shelter), 5x8 Silponcho (primarily rain gear), and emergency bivy in my daypack. But that setup doesn't provide me with a durable groundsheet, and an 8x10 tarp in addition to a 5x8 silponcho seems like overkill for daypack gear.
IA Woodsman, do you carry a 10x10 or similar larger tarp in your daypack, in addition to this Survival Tarp?
