Freestanding? Budget? I have a
Zpacks Duplex and it’s my favorite all time tent for backpacking. I also have a BA Copper Spur UL 1. As far as space and weight, there is no comparison between the two. The duplex is the one I grab every time. BA CS UL3 with ground cover is 4 lbs. The Duplex is 1 lb 3 oz for $150 more $$. Just depends on budget, weight considerations and if you want a freestanding tent. I have handed my Duplex to friends while in the stuff sack and they couldn’t believe my shelter was in the sack. Packed, It’s the size of a carton of milk and featherlight.
