Just made a Shamu, a Baby Orca and a Top Blanket using 0.66 Momentum10 nylon taffeta.
All were made with Climashield APEX (TM) 2.2 which is good to freezing or below, depending on how hot you sleep.

The Shamu had a finished weight of 10.4 oz.
The Baby Orca had a finished weight of 7 oz.
The Top Blanket had a finished weight of 12 oz.
A 3' wide Torso Length Top Blanket had a finished weight of 6 oz.
A pillow made from scraps weighed 3.5 oz.
Stuff sacks for each of the items above came in at 0.3 oz each.

I decided to make all insulation products in future using 0.66 Momentum10 nylon taffeta on the inside, and 1.0 Robic on the outside, so that they will not be ruined when you encounter thorns, etc. I'll also make them, by request, with 0.66 Momentum10 throughout.

Hammock socks will be made using 1.0 Robic. Insulated Hammock Socks will use 0.66 Momentum10 on the inside.

For now, prices will not be affected by these changes. (The Permanent Father's Day Sale continues!)
I hope to get the web site updated real soon!
