The batwings are perfect size for my spotting scope and tripod. Great for going in light and coming out heavy.
2 bat wings work well together on my F1 mainframe and provide a good amount of space for stuff. This works well for a hike or a ruck with added weight. If I was going out for more than a couple days though I would need another compartment.
So far I've only used them shed hunting. With the F-1 mainframe they're great for day hikes. They hold what I need, they're quite, and are super light. I plan to use them with my dry bag for day hunts this fall.
I was worried these batwings were going to be too small to be useful and man was I wrong! These things are huge!
I highly recommend this product
