I really love this wrap. It's a bit too bulky yet for my 3.5 mo old (for my taste) so I tried it out in a ruck with my 45 lb 5 year old, and it made him feel virtually weightless. I am definitely looking forward to using this for back carries as soon as she's ready. The one I snagged was base-2 so I tried to do FWCC TUB but the knot was too bulky to stay under my 15 lb baby's bum securely. The fabric blend made it get so soft and smooshy after one wash and iron, and the black and white gives a true contrast with a sheen to it. I'm not a geo print fanatic but I decided to try it cause I was curious about the blend and weight of it (and it was on sale!) and I'm glad I did. I actually like the way this geo print looks on us.
