This pattern is a ribbed pattern so it fits multiple adult and teen sizes. If you need a larger hat you can use a size larger needle and add more rows but you will need more yarn if you do so.

1 Skein of Cascade Pacific, Caron Simply Soft or Red Heart Super Saver Solids.

Sizes 6 & 8 cable needles with 16 inch cable Or whatever size needles needed to obtain gauge with DPNs to match.
One set size 8 Double Pointed Needles (DPN)
Yarn Needle
Stitch Marker

Note: The Cascade Pacific yarn is lovely to work with but you will use almost all of it so if you don’t get gauge you will need to have a second skein.
