Wiggy's bag drafty and cold for me - what am I missing?

I got a Wiggy's bag this summer on sale and first impressions were good. I finally had a chance to use it in colder temperatures, and I struggled. The bag is rated for 20 degrees and it was about 30. I never was shivering, but I had a hard time getting any sleep. I feel like the insulation is enough to take it down to its temperature rating, but the design of the bag gave me some issues (or maybe it's user error).

First off, the hood was uncomfortable. It's a very basic design, and to seal things up you have to get it very tight. The drawstring is not elastic, which is good for durability but not for comfort.

Directly related is the lack of a neck collar for drafts. This doesn't seem like a big issue at all when you're trying the bag out in your house, but when it's below freezing you feel every little draft coming into the bag.

There is a large draft tube over the zipper that works well, but on the other side, where the top and bottom layers of the bag are sewn together, the insulation appears to be totally sewn through.

Finally, the bottom of the bag appears to be made of thinner insulation than the top. This would work well if I only slept on my back, but laying on my side raises up the sides of the bag and exposes the bottom of the bag to the cold air.

So what am I missing? Although I've read about the draft collar issue before, in general the consensus seems to be that these bags are warm. I feel like if you are a back sleeper and don't mind the feeling of the hood when it's all cinched up, a Wiggy bag is probably okay. But if you are a side sleeper or you toss and turn at all, you will deal with cold spots and drafts all night long.
