In reply to Dave Warburton:
Now that the phuds are made in the UK, why don't you send it back to alpkit and ask them to sew the straps back on. I bet they'd wouldn't charge, or they'd only charge a small fee.
Also, as an aside, does anyone know how you can evaluate different pads? i.e. they're all roughly the same size and price, but how do you know if the foam is better (or worse) in a specific model?
