There is no information about a waterproof column, so it doesn’t seem waterproof. This means it can repel a very small amount of rainfall, like light precipitation. The first is to generate an element of airflow when you’re standing underneath. Yes, it is a completely exposed structure with open walls, but when the hot rays of the sun are beating down, it makes things more comfortable when you have a concentrated breeze flowing through. Although you might think that you can’t get overheated underneath an already open structure, if lots of people are standing inside and if the outside temperature is boiling then things can get hot. Make your next tailgate, campout or backyard party more enjoyable with the Ozark Trail 10? x 10? Straight Leg Instant Canopy. The 50+ UV protection canopy top combined with the 10? x 10? frame provides 100 square feet of shade to ensure you, your family, and friends are comfortable on hot, sunny days. The legs are locked into place with old school metal push button locks, something you won't see on many modern pop up tents now-a-days. These push locks get very difficult to use over time, especially if the tent is used on the beach and exposed to sand and saltwater, causing rust build up. Many newer tent brands like EZ-Up use revolutionary thumb lock sliders or larger easy to release buttons, which are a much better user experience when setting the canopy up or taking it down. The heavy 400D polyester top provides 99% UV protection and is water and fire resistant. There are 4 walls included and one of the walls has a zipper in the center for easy access under the canopy. The canopy folds down to 52.5? in length and easily fits into the roller bag with all of the accessories. It's worth highlighting that despite the advertised dimensions of the 10x10 Ozark Trail, because this is a slant leg shelter the top only measures 8x8. You'll be able to comfortably fit up to 4 chairs underneath the 64 sq. From a positive perspective, the lightweight design increases portability which is certainly important in carrying the tent to its intended location. From a negative perspective, the weight is indicative of a lack of high quality material and components used throughout the shelter. The included carrying bag does not have wheels to aid in transportation, but at only 29 lbs. We don't find that to be a noteworthy drawback as the nylon handles and shoulder strap work just fine in carrying the tent.
