It’s really too early to be talking about the specifics of weight but since I opened that topic I’ll follow through.
My TT Saddle (fly + inner only) weighed 1040g (36.6g) out of the box and 1068g (37.6oz) after seam sealing. The first X-Mid 2P prototype weighs 1020g (35.9oz) and that’s factory seam sealed, so it’s 1.7oz lighter than my seam sealed Saddle.
With that said, my TT Saddle weight is over spec. I haven’t seen many other user verified weights to know if that is the norm or not. TT claims 36oz including the stakes (~2oz for 6) so the fly + inner should be ~34oz but as mentioned mine was 36.6oz without the stakes before seam sealing and is 37.6oz now. It’s hard for me to believe that 34oz Saddle’s from this production run are common, but perhaps so. If at-spec Saddle’s do exist, then they could be slightly lighter even after seam sealing, but within an ounce.
Of course the weight of the X-Mid 2P will also change. I suspect it’ll get slightly heavier because I’m making the floor a few inches wider, but I’m also going to trim a few things so I doubt it’ll change either way by more than 1/2 oz.
So the 2P will be appreciably lighter than my seam-sealed Saddle, but if on-spec Saddle’s do exist then those could be lighter still. Â The bottom line is that it’s going to weigh about the same as a Saddle, but I think offer a long list of appealing advantages including #5 zips (vs clips), higher end hardware (e.g. buckles), more functional vents, quite a bit more headroom (similar to SS2), more vestibule area, much simpler pitch, no sag fabric, better snow shedding etc.
