price is high, but I see the benefit of it.
Best use for me would be space in truck and storage space at home. I could see a use for this as a second cooler for deer trips, without the need to bring a second big cooler or having to store another big cooler in the garage year round. I have one big cooler for my trips, but sometimes if we have a bunch of people hunting, we will run out of space. I would use this as an overflow cooler. Place deer in main cooler on ice, and when full move already chilled deer quarters to this portable bag, and then add new deer parts to main cooler. Or use the smaller bag to put meat in a separate cooler for meat you may process yourself (backstraps) vs dropping off at a processer.
Looks like it has a drain, which is good. As long as deer leg cut ends dont puncture the inside, I see this as a good product.
