I was typing slowly while Ryan answered the question. I agree 2.5oz and change may be about it for the light side. That is unless Cuben makes something lighter. I would say you did trim things real close to get that weight with the spinnaker material. No Fat is good.
Bill,
Q – 1. I cant wait to see that. I think for this next one, you could find a little lighter tie out system. I understand the need for reinforced tie outs, but you could just use another layer of cuben in the corner, instead of all the webbing.
A – 1. My tie outs for the next one will weigh next to nothing. Everything will be Cuben. I have more or less worked that out and have tested my new webbing for strength. It seems very strong.
Q – 2. But I am still wondering what these new ponchos are made of. if it is not NANO or cuben. is it the .9oz sil nylon used on the old one, if so, where dose the weight savings come from?
A – 2. My guess is they are Nano aka Cuben and it says the 12 tie outs are grosgrain. The edges look like they are hemed and I did not nor would I do that on mine. If the edges also are lined with grosgrain that might be why they weigh so much.
I have to laugh at that. 4.4oz and I still think it is to to heavy.
My first Cuben Poncho/Tarp weighs 2.81oz if you don’t count the tie out cords and stakes. It is 48″ wide by 90″ long. That is 3.33 sq yards vs the BMW at 3.66 sq yards. I think I need to up the weight of my next lightest Poncho/Tarp to maybe 2.5oz. I haven’t weighed the new webbing yet.
