The Infinity Strap STRETCH (patent pending) helps with strength and flexibility, and is designed to stretch with very high resistance to a certain point and then stop, much like the human body. The design of the Infinity Strap STRETCH is a dual loop with a subtle twist at the center, forming a shape of an endless figure 8, which is illustrated by the timeless symbol of infinity. Because of the subtle twist in the design, each loop always stays open, making it easy to slip over your hand or foot. The twist also makes it very easy and natural to form a good grip, following the natural contours of the body. It also distributes the pressure away from the fingers more broadly over the hand and wrist. The Infinity Strap STRETCH is made of a high tech high resistance hybrid webbing material that is 1.5 inch wide and available in four sizes and in two colors. The material has a woven braid running through it that grips to the body but stays soft and comfortable. Itit incredibly strong. Also, since there are no metal or plastic buckles or any other parts to get in the way or complicate things, the Infinity Strap is very natural and easy to use. It is also very safe and quiet when it comes in contact with a hard floor or any other surface. It will not get tangled or bunched up in any way. The infinity sign is one of the most elegant, timeless and simple symbols that exists. It expresses an incomprehensible idea by implying the potentially endless motion of drawing a figure 8. It is perfectly symmetrical and balanced in design and function. The uses of the Infinity Strap STRETCH are endless. Just think of the possibilities when you use two or more!
