Unique Striped Crochet Hat Pattern – Geowave Hat

This post may contain affiliate links, view my disclosure policy for details.

The Geowave Hat is a striped crochet hat with a really unique texture! And this crochet hat pattern is definitely simpler than it looks.

This hat is crocheted from the bottom up, starting with the ribbing. And the best thing is, once you get the hang of the first row or two, it’s a one-row repeat for most of the hat body. So, it requires just a little concentration at the start, and then you’re good to go 🙂

The crochet pattern is written for 4 sizes, from Baby up to Adult Large, so this is a great pattern to make in bulk for gifts.

How to crochet this unique striped hat

This striped hat is crocheted from the bottom up, using 2 colours of #4/medium/worsted yarn.

First you will crochet the easy single crochet ribbing in a long strip, then fold it in half to seam.

Next, you will work the rest of the hat in the round, joining at the end of each round with a slip stitch. This section of the hat might take a little bit of getting used to for the first round or two.

But once you have the hang of the Front Post stitches used to create the “V” shape, you will be able to put the pattern aside for a little while!

The final section of the hat is a series of “decrease” rounds, to reduce bulk at the top of the hat, and make it easier to “cinch in.”

Note: the print-friendly PDF version of this pattern also includes a stitch diagram for the entire hat (body and decrease rounds), in addition to the written instructions.

Crochet Hat Sizes

This pattern is written for 4 sizes: Baby, Toddler/Child, Adult Small, Adult Large. As the hat ribbing is quite stretchy, it is a good idea to make your finished hat 1″-3″ / 2.5cm – 7.5cm smaller than your head size.

Supplies needed to crochet this hat


Any #4/Medium/Worsted weight yarn will work great for this pattern. For my hat I used Paintbox Yarns Simply Aran (184m/201yds per 100g skein; Weight 4/Aran; 100% Acrylic).

Baby76 yds / 69 m 52 yds / 48 m 128 yds / 117 m 
Toddler/Child90 yds / 82 m 64 yds / 59 m 154 yds / 141 m 
Adult (Small)113 yds / 103 m 80 yds / 73 m 193 yds / 176 m 
Adult (Large)133 yds / 122 m 98 yds / 90 m 231 yds / 212 m 


RIBBING: 4mm (G-6) crochet hook (or hook required to meet gauge)

BODY: 5mm (H-8) crochet hook(or hook required to meet gauge)

The ribbing of the hat is crocheted with a smaller hook for a nice, snug fit :-). For the main body of the hat, you will use a larger hook, that is easier to work with for a worsted weight yarn.
