I've got a Harkila deer net - the one with hoops sewn in. I like the fact that no part of the net actually touches the. carcass. Useful if you are away from the chiller and need to hang a deer somewhere flies can get at it.
To prevent tick and ked infestation in the truck, we also tend to use nylon deer shrouds ( not the cotton ones, which are useless) from The Countryman of Derby. They are big and stretchy enough to sleeve a decent sized Red or a couple of Roe.
