Hi All, I'm thinking on doing another backpack. The design will be roughly a atompacks atom+ Propabaly this one is going for sale or I might make 2 I might try the dyneema gridstop from Adxpert. Does anyone has experience with this fabric? Do you have to bind the edges to keep it from fraying? I usually just stitch the seems twice. Otherwise I'll just go with xpac21. And for shoulder straps, does anyone have a favorite pattern? The last ones I made work but they are a bit to wide and brush against the arms when walking. Any help is greatly appreciated!
