Mod Swad Venti Flo Fashionable Baby Swaddle with Airflow Technology ~ Choose Size/Color (Medium 14-19 lbs, RockStar)

This does not have an adjustable length at the tail end just so you know. It may say so and appear that way with the knotted end in all the pictures but there is a sewn-in seam so my very long 3 month year old at 26 and a half inches, 14.6 lbs. already has his knees bent while laying in this. Very disappointed in the false advertising, wasted $30+.
