inner for grace duo?

I'll be interested to see what kind of feedback you get because I have the same question with mine. I have been working up the geometry to make a cuben "door" with the idea of using bungee and mitten clips to attach it. I would actually run it under the tarp from the clips on the front two corners up to the first clip right above the head end (not the spot where the pole goes but where you would hang a bivy). I'll probably construct a model from window film to try it out. The variable geometry based on the pitch height and height of the sides will make it interesting.

As a not take extra weight, I thought about rigging my rain jacket to serve the same purpose..

I have a GG SpinnTwinn. My thoughts are that once you start adding things like doors and floors, then you have abandoned the point of a Tarp and are best to utilize a shelter that is already made like you want. I think your original point about site selection is the key. If you are going to be in a situation, like a group, where you may not have the benefit of site selection then perhaps the secondary shelter choice is the better bet.

For my 2 cents… In my duomid, the bearpaw 1p pyranet with cuben 10" sides and cuben floor would be a bomber addition. I liked it much better than the solo innernet produced by MLD. Plus it leaves everything pole outward for quasi-vestibule cooking / woodfire camp time when not in use. It's so bomber with the cuben surround that I doubt much could get in….

Worked for me so far. Hope this helps.

Thought Duomid not grace duo. Idiot.

Bearpaw is still the right idea. Minimalist or net tent with front cover or solid front would work.

1) a door could be rigged easily, a triangle(material of your choice) with mitten hooks and shock cord would do the trick

2) probably is correct to just use a tent. Sight selection almost always sucks when with the boys and distances aren't too long anyway. ultra light is great when on my own (never happens) but the load always increases with scouts, especially the new boys.

3) i kind of worry about the amount of space unblocked at the front of the tarp with a one person bearpaw or serenity, may need to myog my own.

4) or, gear swap grace and stick with tarptent

Thanks again

I have a nylon MLD SS, and it has not worked out well in a situation similar to what you described (rain/wind blowing in through the opening of a A-framed tarp). Unless you pitch the tarp high, there is not enough upward pull on the door of the SS to keep it very taught; it just billows and the rain gets around the edges of the fabric door (through the netting).

I got lucky, as the thunder storm only lasted about 20-30 minutes. Had it have been an all nighter, I would have had to pack up and re-pitch the tarp another direction.

I have switched to a beaked tarp (MYOG), and hope to make a cuben version of the SS with catnary seams all over (hope that helps with the tension issue).
