Yay for fluffy mail!

I usually just have DS in a nappy when carrying, but it's too hot for clothes anyway atm.

Don't know anyone who has used those wraps. Only one way to find out though! They look beautiful, but there's no way of telling how supportive they'd be without trying them. You could find out whether it's an airy or dense weave though, the denser the weave, the more supportive it generally will be. I'd be inclined to check the length and width before buying. Girasol is a wrap brand that also uses Guatemalan woven cottons which are purpose woven for babywearing.
