I got this waterproof camo backpack cover to try out from Dagio, an online retailer.
This is a camouflaged waterproof backpack cover meant to fit up to 45 Liter capacity backpacks. With the stretchy elastic band it can fit smaller back packs as well. Plus it fits snugly and covers your bug out bag well.
Being camouflaged it is very good for turning your street backpack into a stealth bug out bag in emergency situations. You can take your red, green, blue or pink hiking bag and make it into a stealth camo BOB.
I will be doing extensive tests on this camo backpack cover soon during the hunting season. Stay tuned for a full video review.
