The Guide Gear one doesn't look like it has the side pockets or the backpack straps like the High Sierra one that RoatanMan recommended.
Even though the High Sierra Bag is sold out on Sportsman Guide, there are still other places to get it for a few bucks more. I know because I finally broke down and bought a couple. If you want blue, it's $59.97 at
www.campmor.com. Red or black or blue for $69.95 at
www.sierratradingpost.com.
This bag is the AT Gear Classic High Sierra AT102, it lists dimensions 36x16x14 in. and some sites say the capacity is 8060 cu. in. I weighed the bag and it is 9.8 lb. It looks like it has been discontinued and replaced by the AT Gear Access AT202, which for some reason lists larger dimensions of 36x20x14 but has smaller capacity of 6588 cu. in. The cheapest online for that model is about $120. It also comes in microsuede (MT202) but that looks too fancy for wet dive gear. Check out

Just got my bag, it looks pretty nice. It has a mesh pocket along the top of the drop-bottom compartment, and the backpack straps are thick and zip away behind a padded flap for check-in. The handle has two locking positions. Looks well-made. Can't wait to try it on our Big Island trip next week! Thanks for the tip, RoatanMan.
