I'm about to go on my first stalk in a couple of weeks and hope to bring back some venison. I'm more than familiar with abject failure from fishing and wildfowling, but I always like to imagine that things will work out, it makes it more enjoyable. I have a rigid Coleman icebox that I've used for years for carrying fish, small game, and of course picnics. It's very good, and I'm pretty sure it's about large enough to carry two roe haunches, one or two shoulders and a saddle. However it is a cumbersome of a thing to carry around when it's empty. I've seen plenty of cheapo fabric ones over the years, but apart from the fact that they were generally pretty useless at keeping things cold, they were also flimsy, and probably not really water/bloodproof.
Is there such a thing as a robust, waterproof and reasonably well insulated collapsible coolbox?
Grateful for any recommendations or advice.
