I’ve decided to make my own “snack bag” for the bike, basically used the idea from Alpkit Stem Cell (with my own dimensions) and make my first piece of gear with liner. Didn’t go as I expected, so at the end I had to cut some corners. Normally the easiest way is to sew the liner and then sew it to the outer shell, but the position of stitching needs to be carefully thought through. I made mistake and some of the stitching are inside. Minor detail next time I’ll do it properly. All in all the bag is doing the job as you can see.
