Thanks for that Denni, a useful site. Looking at the FAQ though, 'most preloved gently used unwanted outdoor clothing and equipment' is probably a description that precludes my day pack. It's only going because it has to - it's literally falling apart.
No worries mate, it is a good resource.
A lot of my tents were falling apart but a few groups took them to repair, use as temp shelters, improvisation etc so you never know!
Thanks again. I may put it on there if no-one else can suggest anything. I thought about getting it repaired myself but gave up on the idea when I realised that it would cost about the same as buying a new one!
It can probably go in a textile recycling bank, depending on your area. You may need to cut off any plastic and metal bits and recycle them separately.
