I have only one edit and one comment.
Comment/Edit: I noticed in your spec chart that your measurement for shoulder width appears to be the width across rather than the circumference like the manufacturers. Even though they will still be different, I think it would be better to list the circumference for comparison.
The fabric feels great, the overall weight is is great, and the bag stuffs down to the size of a loaf of bread.
EDIT: eliminate one of the "is" from the statement
