There is no soaker.....the crotch area of the dipe does have extra absorbancy/material in the center inside but no sewn in doubler at all....I got a hemp tri fold doubler that is pretty thin but it absorbed very well...I just folded it and laid it inside my fitted.....and I washed and dried these last night and they took NO time at all to dry....I don't think any of my dipes have ever dried that fast other than my pocket dipes which I normally hang to dry anyway.....they are super soft too....sometimes hemp dipes feel a bit stiff to me until they are washed and dried a few times, but the hemp fitted was extremely soft when it arrived yesterday (not sure if they wash the material a few times before they make the dipe or what? it feels as soft as a t-shirt though) and of course the terry/flannel fitted was very soft too. I think I'm going to get a few more of those hemp tri folds too....since they are thin but absorbant, I was thinking I could fold them and lay them horizontally across the front of Tommy's fitted dipes since we sometimes have issues with the front of the dipe getting more soaked. I tried the flannel terry dipe this morning with a hemp tri fold in it and it did great....my son had a huge, bf poo accident this morning that was pretty liquidy and it all shot up and off the tri fold and into the dipe around the leg opening....but it didn't soak through to the outside of the dipe and get on my cover and it didn't come out of the leghole either....maybe it would have if I hadn't changed him so quickly...but a lot of my other fitteds would have immediately leaked or came out of the leghole (as a matter of fact, I put a Doodlebottoms fitted on him right after and he pooed again and it came out all over the place and was all over his fleece cover)....so I'm still impressed so far.
