Made from Newlife, a unique, high-tech fiber made from recycled plastic bottles, the Tricot Slen Cool is extremely light, has equal carrying capacity to a woven wrap and is as flexible as an elastic wrap. With the same special knitting technique as our original Tricot-Slen Organic, the Tricot-Slen Cool offers perfect support for all babies, from newborns up to toddlers of 40 lbs. This hybrid wrap can be worn in many different positions and since the same tie is used for all carrying positions, it is easy and quick to put on. Its natural stretch guarantees a perfect fit and makes this lightweight wrap comfortable and easy to use. This moisture wicking fabric is machine washable and air dries quickly. Delightfully cool in the hot summer months, this wrap is still cozy in winter's chill. Thanks to its remarkable stretch-stop qualities the Tricot-Slen Cool also offers long lasting support, and in contrast to baby wraps made out of Spandex or Lycra, it does not cause your baby to bounce up and down.
