The Kingman Spyder Duffel Bag is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
BIG Lots of room for markers and extra stuff.
Not a lot of pockets but that ok with me.
i used this bag and it never had any problem with a u-shaped zipper operation make it easy to open. Plus it is big enough i am able to put two markers in there plus 2 co2 tanks and other extras in the main conpartment. So it is very conventent and is great for paintball or just to hold stuff.
