Stumbled upon this;
Saw it the other day and read through the whole thing one night. I think that thread has finally helped me see the light in regards to why you would use a quilt over a bag.
As here I am looking at getting one of these (Or an EE Revolution/S2S Ember). Just need to figure out what temp rating I need to go for.
Simon at Tier Gear makes a synthetic top quilt if that’s more your style. Less of a huge investment and a great guy to deal with.
