Having said that Swaddlebees make a pocket all in one, the pocket is for extra boosting. But i would never use mine without extra boosting, so i guess it is an all in one, just not an absorbent one. Am i making any sense

BBH do aswell. I use mine during to day with no extra booster and at night use two.

I too use a mix of velcro and snaps and velcro is easier for DH but I prefer snaps in the washing.
