Pack of three muslin swaddling blankets made using rayon from bamboo fiber. aden + anais® wraps are the ultimate in breath ability and softness. Muslin's light, open weave allows a babys body temperature to regulate itself naturally, which helps to reduce the risk of overheating. It is gentle on babys skin and durable for everyday use. The more you wash aden + anais® wraps, the softer they get. aden + anais® wraps are extra large, measuring 47 x 47, so that new and seasoned parents alike can swaddle babies of all sizes with ease. Traditionally used for swaddling, our wraps can also be used as burp cloths, nursing and stroller covers, portable crib sheets, stroller and car seat liners, tummy time blankets, change table covers, and more.
