They now have the MLD Silnylon Mid.
They have done a lot of product testing for me. They are awesome.
(Never was a Cuben version that they used.)
First Spinntex Mid:
An EARLY proto way before I put them on the website for sale…They used it about 90 nights. A zipper failure was starting- The zipper was a tiny one and with all the sand, etc. everyday it was starting to wear at the bottom and so I sent them a second Spinntex Mid before it totally failed. If you have been following them closely- you know they don't exactly baby their gear either!
Second Spinntex Mid:
They used it for about 30-40 days in some of the the worst of the storms they have seen. It had lots of small improvements over the Proto, mainly a bit taller and a much better vent plus a beefier zipper.
It was way cold and Hig tripped (or something like that) and one of the secondary tieouts point guylines got super yanked and caused a fabric rip. (I now use even beefier reinforcement patchs at the secondary tieouts too. I also suggest folks use a short loops of bungee on side panel and secondary tieouts . -It's really light Spinaker after all…) I think they were gonna sew it back up but I offered to send a Silnylon version for the rest of the trip into the harshest and more remote part of the trek.
Third Mid: The one pictured. I was out of Spinntex at the time and sent the Silnylon version. So far after about 35-45 days I've not heard of any issues. I also thought they might like a bit of Yellow in the Mid! With all the pics of the snow, I think the silnylon is better for when you have to dig it out everyday for day after day. -In that one pic the snow is freaking deep.
