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
I ordered two batwings to go on my Mainframe pack. They are super versatile and can be manipulated in so many ways to accommodate any type of load that you want to haul. Great buy!! Awesome job Eberlestock.
