These are not cheap, but a few of us use them. Look at the QE section ... the
Biker is the one I have, there's a 'porch' area at the front which is good for your clobber.
They also do a purpose-made groundsheet for 'em, they're the right shape etc.
A mate put me onto them and he's used his for 10 years or so he says.
