I did have a few inches along the edge for some clothes, a water bottle, and a headlamp, but that could have been made wider with a narrower sleeping pad. Size is perfect for day trips, smaller individuals, and teens. Great for hiking in warm weather, thanks to the breathable construction, mesh straps, and hydration bladder hook up. The main compartment is big and easy to access through the cinch closure, and also includes a quick-access side zipper opening. The removable top lid can zip off and function as a smaller, more manageable daypack. There are side water bottle pockets on the right and left, and its compatibility lets it serve as a great hydration backpack. This pack fits me fine and is very comfortable for lightweight loads. With that question being floated, we decided to travel down the path of discovery and start to take a closer look at Ozark Trail and some of their products. We just completed a review of the Ozark Trail Tumbler line, which is not only budget friendly but also well performing. This unisex camping and hiking backpack is large enough to hold supplies for several days, but not bulky or inhibiting enough to become a nuisance. The Ozark Trail backpack has a total of 22 liters of capacity with several pockets for your essentials. My own personal beverage drama every summer has really pushed me to do this review. To me, worrying about the temperature of the drinks I have on my boat is the absolute last thing I want to be thinking about when I am heading out on the water. We crossed Henderson Creek later in the afternoon, following the trail along it for several miles until we crossed it again, via a nice, wooden bridge built as an Eagle Scout project. Roam and I camped by the creek here on a prior hike, but, it was early for that. So, we mushed on to Neal's Creek, where we hoped to make camp. I did finish my activities very sweetly and was able to walk and hike without carrying anything in my hands. I drooled over all the lightweight packs from the major manufacturers for a few years. There's no way I can justify paying five times more for something that might carry just as well. I know some will immediately dismiss my review simply because I bought this pack at WalMart. I've been attempting to drop weight for the past several years, mostly because my knees can't handle it.
