Our large size Pop Up Tan Tent allows maximum light illumination with minimal solution escape, utilizing three shoulder height heavy duty stain resistive vinyl windows with a clear top. The material we use is composed of FIRST QUALITY 210D washable Polyester zero flaw fabric. The stain resistant thick floor is waterproof and leak proof. Double stitched seams, with a durable nylon dry rot resistive thread. Framing composed of rust proof "Low Memory" spring steel that supports the room without sagging, allowing easy "coil back" folding into the collapsed circle configuration for storage. Extraction Fan opening at the back of the tent is a "roll up" design that will fit up to a 20x20 extraction fan. We use Heavy Duty Velcro to keep the rear opening closed when not in use. Velcro is installed completely around the opening insuring, 100% closure. NO MORE BROKEN ZIPPERS!!! Included with every popup tent is an oversized carry bag. This allows for easier tent insertion. We have eliminated the zipper closure using Velcro strips. This eliminates broken zipper issues. The bag is large enough to also carry extra items like towels etc., and can be easily toted with the "true shoulder length" carry straps. Triple stitched handle provides firm attachment to the bag body. Tent Size: Entry opening: 6 1/2 ft tall and almost the complete width of the tent, Entry Width is 4ft to allow easy access for even the tallest clients. Overall tent size is 4x4x7 and less than 8lbs. (yes it weighs a bit more than others, quality fabrics make the difference).Our product has NO DOOR as we have found it is rarely used and only adds bulk and weight. Warranty: The tent comes with a 30 day product replacement warranty against manufacturer defects.
