This is the lighter weight or cooler version of the Baby K'tan Carrier/Sling for baby wearing. It is part mesh fabric, part cotton to give you the choice for warmer weather or for Mum & baby as to which fabric is more suitable for each. I love that choice as both my babies and I get quite hot even without a carrier. There is a sash that turns into a pouch which is great for storage at home, diaper or stroller. Comes in a few different colours, mine is black so it goes with everything which is important to me.
The draw back is that these are sized and there is much debate as to whether they fit accurate to size or too big/too small. Most likely you have to buy a size for each wearer. For me I was between sizes which made it less than perfect sizing up or down. So for me I had very limited use with it. Still think it is a great product if it fits you appropriately. Definitely try before you buy if at all possible with Baby K'tan carrier/sling. I also only think it's suitable for for the first few months or for before baby's weight is too much of a strain for use of a carrier with no back support. I also found there's a learning curve to getting it on properly to the fabric of your choice.
