If you want a Massdrop Dan Durston X-Mid, you’d better hurry as there’s only 17 left on this drop! https://www.massdrop.com/buy/massdrop-x-dan-durston-x-mid-1p-tent#overview
If you’re interested in the development of this and the two person version, have a look at the comments as there’s a lot going on in the background.

Thanks Robin, for flagging this up. I’m sorely tempted, but having read the comments, and being 6’6” tall, I think the 2p version might be more suitable, at a small increase in weight penalty. Plus I can take the dog or one of the kids perhaps too (my kids are still young enough to want to go camping with Dad!). Please do keep us posted if you hear about the 2p version. Many thanks, Mike.
I suspect the 1P is too short. Looks like the 2P development is well underway. I’ll post when I hear anything 👍
