Sewing work on the bag is now complete. There are two pockets for the mat at each end and a band across the middle.
This is what the front of the bag looks like.
During the summer I can use the bag as it is, but with a down sleeping bag inside it, it is a little bit tight. The zip baffle was only 5cms wide, but they have sewed on an extra baffle which is 20cms wide.
This means that although I cannot close the zip completely, but I can close the baffle using valcro.
I am considering further alterations in the future so that I can close the bag completely.
