does anyone know where I can buy one of these?

I've heard you can get a lot better for your money for a bag liner. These dont last long apparently.

SnugPak make one I've got one, proper nice and cheaper than a Rab. Mine was made in england too, don't know if they still do that. Got in a local army surplus shop. I'm in town tomorrow so I'll have a look and let you know.

I've not tried a Rab one but agree the Snugpak one is great, you can get them for a tenner at The Gorge Outdoors. Still made in the UK, too!

Local army surplus sold out and never got any more, still it was worth an ask. If you can get one, get two i know I'm getting another.
