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. My shelters have gotten lighter as have my sleeping system — next in line for a diet was my carry system. Funds, however, were non existent and my CFO (i.e. my wife) wouldn't increase my discretionary fund. I priced other internal frame daypacks before my trip and this was by far the cheapest. I took this pack on a 5-day mountain bike ride from Pittsburgh, Pa., to Washington, D.C., and it performed very well. I tried actually sewing one on, but I don't have the right size buckle to go with the strap, so might won't hold tight. I might actually pick up another for my son to use. I also use a Marmot 20 liter pack which does have a thin hipbelt, but it is more limited space-wise and weighs a couple of ounces more. Features taken directly from Walmart.com sales page. Wetlands give way to ridgelines at the start of the Blair Creek section. The 26-mile route follows Blair Creek south as it carves down a valley through oak-hickory-pine forest before merging with the emerald waters of the Current River. Here the 30-mile Current River section picks up, following the river for two miles before veering south toward Stegall Mountain. Enjoy views of the Ozark landscape as you gain 500 feet of elevation up 2.5 miles to the top of Stegall Mountain. I have noticed that when I fill the bag up full or close to full it puts stress on the stitching. To resolve this issue, I do not fill it completely up with heavy stuff. Honestly, most of my trips it’s a quarter full and the water bladder and extra water bottles are what makes it heavy. After the last few trips and hiking with a near empty bag, I decided to get a 20-liter bag since my gear only fills up about that half my normal bag. My suggestion is to get a smaller bag for shorter trips so can save on weight. Every pound does add up and if you cut the weight down by 5+ lbs. We loaded the bag up with everything we might need for a 10-to-12-hour day out on the trails. Of course it has no side water holsters, or lid pocket, or hipbelt strap, but I think that all contributes to its low weight. For the water bottles I just use Platypus .5 liter and 1 liter flat style bottles, which you can fit in the main body of the pack on top of your other gear.
