Ozark springs see a lot of rain and varied temperatures; Ozark summers tend to be hot, muggy, and wet; Ozark winters can drop below freezing. Wet weather is common to the Ozark climate, especially in late spring through summer, and fosters a breeding ground for bugs, mosquitos, and ticks. Consider bringing waterproof shoes and treating your clothes ahead of time with permethrin to repel insects. In the colder seasons insulating layers are a must, and a good rain shell for you and rain fly for your tent are necessary year-round. I also don't really prefer single compartment stuff bags, but, this works for what I need. Just about every other daypack I've had falls apart under the weight of my books (med school). I also like the fact that for my outdoor activities, it's designed to hold a hydration bladder. It even has a rain cover built in, which is great when I'm riding my bicycle across town on a rainy day. This hydration compatible backpack has a connection for a water bladder built in to the design. It also includes loops to hang your trekking poles when not in use. The Ozark Trail does not have permit, parking, or registration requirements for its trail sections. 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. All told, I've had the pack on my back for about 50 miles. Keeping the load under 15 pounds seems to be the key. I really wanted to use it for our fall two-nighter on the AT, but was unable to fit my bivy with a 20 degree Kelty Cosmic down bag inside. I contemplated stepping down to the 45 degree bag, but thankfully, did not. Exploring Missouri’s scenic Ozark backcountry is one of the best reasons to head out on the trail. The Ozark Trail Association marks and improves the trail and ensures backpacking campsites are well maintained. Mostly divided into linked sections, the trail winds through 390 miles of rolling hills, stone bluffs and cool streams in central and southern Missouri.

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.
