The BB-slen is a very comfortable woven sling, made in a Fair Trade project in India using the best weaving technique for slings. They are slightly wider than most woven slings, making it great to carry toddlers or older children. I've personally used my BBSlen with my 4 month old and didn't notice the extra width, so this really could be the perfect infant-toddler+ sling. The slings come wonderfully soft and floppy right out of the box. They are slightly thinner than many slings, which makes it a great year round wrap.
