Climashield Apex needs quilting?

all of the Apex quilts i have seen on here have been sewn around the perimeter only.

I didn't quilt the APEX "couples quilt" I put together for my brother-in-law last month. From handling the CS, I can say that it is a fairly "tough" insulation; it took enough pulling at scraps to break them up that I'm fairly confident it won't need quilting to stay in place. Just make sure you sew all four sides to the shell, that's all.

Easy-peasy.

When I did a 2.5 Apex quilt (big one – around 50" x 90" I think..don't quote me..) with M50 and 5 mm silk last year and all I did was sew it around the four edges — ended up with a 14.5 oz. monster quilt that is perfect to use in the late winter early spring with a bivy or net tent (had it down to 40* very comfortably with a fleece hat and almost no base layers — it is very warm stuff even though it doesn't look like it).
