If I was to buy another 2 person tent (use a hexamid twin now, and yes it is > $500) it would be the SMD cuben Haven and net inner.
1. Double wall , 26 oz
2. Haven tarp is taped, no sealing required
3. It can be split so each person can carry part of the wt, hybrid tents like lunar duo are one piece
4. You can take just the tarp much of the time (10 oz)
5. Plenty of protection
6. Use it with a bug bivy or solo inner net for a 18oz solo tent
7. Repair it yourself with cuben tape if you get a hole, etc.
As far as Im concerned, its the best 2p item on the market right now for people wanting a full tent. The hexamid is light, but it takes a little work to stay dry in it.
