Evo 5900, H2O sleeve, gun sling, platypus 3L

Bought these items for an upcoming auodad hunt in February. I had purchased many different big name bags and returned them as they didn’t carry the weight they were tasked with. I was about to settle on my badlands 2200 bag that I use for archery when I found SG. I said ok last company I try. Honestly, I didn’t want to but my gf kept pushing me to do it and it is the best bag I’ve had on my back with 60 pounds. It took some getting use to as there are no pockets, yet I kinda figured it out. Definitely a great find. Yes they are expensive and the warranty is limited but it’s worth the money of comfort.

The Best I have ever had!!

Heavy duty construction. Well engineered and user friendly. Purchased the hydration bag for a better method of positioning in the backpack. Worth it.
