I wanted a bag to replace the gas mask bag I use for hunting. It was falling apart because I use it all the time for hiking and outdoors use. I could not decide between a Mongo or this bag. I decided to go with the grey colour, almost all my gear is grey. I am happy I did. The water bottle holder fits my camelback 20 ounce really well. I can carry my essentials for a day out. I use the waist strap and put a bear spray can holder on it for easy access. The CCW pouch holds field guid books well. The semi hard pouch holds my phone for quick access, for the camera. Great for everyday use. It does not replace my hunting bag but it saves it from the daily use I put it through. Maybe I will purchase a Mongo S, when I can find one, for hunting. Not left handed, but I like to sling my rifle on my right side and hitting the bag on the right gets annoying. I am very happy with the Wolfspur and highly recommend it. Adventure Gear was great. Shipped it same day as I ordered it and I got it the next day, perk of living close. Will order from them again. Thanks for the great bag and experience.
