I bought my frame at a local retailer and recently purchased the Bat Wings and Vapor 2500 V2 directly. Had been using an early model of the X2 but decided the frame and various options would provide a better weight balance based on panned outing. I will report back on use after next Elk Season. Flexibility in a fact

I love the Batwing bags. They are the perfect day bag setup with my F1 Mainframe.

Two batwings on an F1 mainframe is the perfect sized pack for hunting. If you have large puffy jackets or rain coats that you take off when you're climbing a mountain, just put them between the batwings and the mainframe and you're golden.

My husband was elated to get this surprise for his Elk hunting trip! It worked amazing for all his needs .

They fit great and there is plenty of room for spotting scope and gear

These are awesome…

I have the Little Brother Pack which is pruported to be EMOD compatible. I ordered the batwings to attach to the pack...only to find out that this particular combo of "EMOD" items does not in fact really work...It is a good idea but there needs to be some more clarity on which EMOD items are actually compatible with others...

Terrific way to add more storage space to your backpack. It makes it real easy, adding these two bat wings on each side of your pack. these pouches make it very easy to access for anything that you put in them. 

bat wings work great open up for big hauls , close up for stalk n move.

The only reason this isn’t 5 stars is that the zip-one’s should have a clip to retain and make sure they don’t unzip.
