I love my WF13!!!
The pockets and dividers are great on this bag to keep everything organized.
The game strap is an awesome idea!
But most of all, I love how waterproof the bag is. I left my bag in the bed of my truck a while ago and it poured rain all night. Convinced that my stuff was wet due to prior experiences with other bags, I went to empty it out to dry everything and to my surprise everything inside the bag was completely dry.
Yes, the bag is expensive, but it is a very HIGH quality piece of equipment.
Whether or not you believe it's worth it is up to you. But if you can afford it, I highly recommend it.
