Boot liner L494 RRS

[croftsj]

Relatively new to RRS ownership and having owned my RRS for 2 months now it's overdue a decent boot liner.
Everything I've found online seems to be attached with double sided tape and/or some velcro, having had one like this in a 5 Series estate the glue dries up quick and it starts coming away pretty quickly.

Can anyone recommend a good liner for the boot please? Not bothered about split rear seats as we rarely use them, doesn't need to be Gore-Tex or hand stitched, it just needs to keep spaniel detritus off and be a good tailored fit.

Thanks.

PS Loving it so far.
