The guy is kinda annoying but I think these things are better at inpsiring people to do DIY rather than step by step instructions.

As far as the bag itself here are my thoughts.

1. It's only single layer, with stiching all over the place....Therfore it is going to leak like all hell.

2. Definitly didn't show enough putting it together. I've made three bags so far and I would be interested to have seen more of that. Especially strap placement... It's a *****.
