Notes from the Little Turtle Knits website:

"Once again, LTK is at the forefront of diapering innovations! We've combined the reliability and ease of our quintessential soaker with the versatility and trimness of our ribby wrap into one ultimate pattern- the hybrid rib!

The hybrid is a traditional pull-on soaker, with trim ribbing in the crotch to fit neatly under winter clothes and still stretch to accommodate even the bulkiest diapers with ease. This soaker features unique gussets to maximize blowout protection and keep the wetness INSIDE, where it belongs! And best yet, we've written it in two easy to read charts, one for a daytime weight using our 3 ply or other equivalent dk weight yarn, and one for a nap/nighttime weight using our 2 ply or equivalent worsted weight yarn. So, whatever yarn you've got in your stash, you can make this pattern!

With detailed instructions and an appendix chock full of techniques, this pattern follows the high standards we've set here at LTK. With sizes from preemie through extra large, this pattern will get you through all the diapering years."
