The scarf itself is simple in concept; a larger than normal, looped infinity scarf. Specifically it measures 60" in circumference and 36" in width. If you're not good with visualization (like me), it's big enough to provide ample coverage worn draped over the shoulder, looped around the neck and hung over one shoulder, or (my personal favourite) around the torso for full back coverage (hurrah!).
The material is light-weight and breathable; which prevents baby from overheating. I love that the scarf provides discretion in public, but also keeps baby focused and not distracted by what's going on around them (even as wee ones my babies would prefer socialization over eating). I've even been known to sport my nursing scarf sans baby - they're stylish even when not in use. Oh, and you can also wear it as a dress!
Of all the products I've purchased for my babies, my nursing scarf is the only one I know I'll still be using longer after my nursing days are over.
