Hi, don’t throw your pack away...if you have a sewing machine it’s relatively to add extra foam to your straps. I use a home made rucksack and the straps are made as follows: stitch a flat ‘sock’ in the shape of the strap pads and then stuff it with foam cut from an old 6mm ccf pad. If you want more comfort then double or triple the foam. Then you can attach your ‘socks’to your existing straps. I’m sure you will find some suitable fabric (nylon) in your attic or a charity shop, but you’ll need heavy duty polyester thread. An old singer sewing machine would be most effective. If you decide to try this feel free to message with any questions, good luck
