What Redditors Say
Best praise vs top criticism for Zpacks Duplex
Best Praise
+13 pts“I have used Duplexes for more nights than any other tent. DCF floor is fine without a footprint with no abrasion problems that I have noticed. I've used an X-Mid Pro 2 for more than a year. The silnylon is fine, but I use a polycro footprint (about 50 g). I cannot imagine either getting shredded at all even on granite. Besides, DCF is trivially patched. I suspect silnylon is as well. I do carry both DCF patch/tape and silnylon patch in my repair kit.”

+6 pts“That ain't 0.5. If you look at the tent its an old ass duplex that has been patched. Probably sold by an thru hiker (remember that the dcf are supposed to hold one of 6 month hike) and that guy complained when it was shredded.”

+10 pts“I live in an area with tough water sources and everyone I’ve ever known that used a BeFree clogged their filter and had it die a very early death. I would never buy any filter you could not back flush. I think they’re shitty but just my opinion based on the four or so I’ve seen fail.”
