The Leg Shield is the perfect solution for protecting your right pant leg from hard-to-clean grease stains and preventing pants from getting jammed in the front gears. With the existing trouser clips and straps, grease still gets on pants when rubbing against the chain, the strap/clips slip down, or come apart. Additional Uses: A pair can be worn for protection against rain/dirt while biking, the neon yellow Leg Shield is very bright and enhances visibility to traffic, and they can be worn for general lower leg protection outside of biking. The Leg Shield was built to last and comes with a solid 3-Year Guarantee. If the Leg Shield does not last 3 years, we will replace it for free. It is made with strong zig-zag stitching. It has three premium Velcro style straps which are easy to tear off, fit securely, and can withstand heavy usage. It is made with a thin layer of neoprene which is flexible and durable. Cyclists are free from worry and concern about ruining their pants and can have a safe and enjoyable bike ride. Universal size that fits most adults. Fits calf sizes between 9-18 inches (23-46 cm). Calf measurement is the circumference at the widest part of the calf. Easy on/easy off design. Easy to carry or store, can conveniently be stored around the frame of the bike. Great for bike commuters and recumbent riders. Hand wash and line dry only. Product Dimensions: 11.5 inches tall & the neoprene is 2mm thick. The Leg Shield was designed to be worn on either leg. The Leg Shield can get warm. Wearing the Leg Shield slightly loose will make it feel cooler. Use the Leg Shield and you don't need to install a bicycle chain guard. Each order is 1 unit, not a pair. Makes a great gift.
