New collection inspired by I Want My Hat Back launches as part of Hanna’s Bedtime Stories, celebrating the shared tradition of reading together

PORTLAND, Ore., July 28, 2026 /PRNewswire/ — Hanna Andersson, the trusted children’s apparel and pajama brand celebrated as the “Champions of Childhood,” is partnering with Caldecott Medal-winning author and illustrator Jon Klassen to bring the beloved world of I Want My Hat Back, published by Candlewick Press, to life through an exclusive, limited-edition collection for the whole family and a live story time experience celebrating the joy of reading together.

Launching July 29 (available now for Hanna Rewards members), the collection transforms Klassen’s iconic characters, including his bear and rabbit, into pajamas and apparel designed to inspire cozy bedtime routines and meaningful family moments.

The collection is part of Hanna’s Bedtime Stories, the brand’s growing platform dedicated to celebrating reading as one of childhood’s most enduring rituals. Hanna’s Bedtime Stories aims to build connection through storytelling by merging the magic of reading bedtime books with soft and coveted PJs featuring beloved story time artwork.

A longtime favorite among parents, educators, and young readers alike, I Want My Hat Back has become a modern classic thanks to Klassen’s distinctive illustrations, subtle humor, and ability to create stories that resonate just as deeply with adults as they do with children. That multigenerational appeal made the partnership a natural fit for Hanna.

Throughout the design process, Klassen worked closely with the Hanna team to ensure the collection remained true to the spirit of the book, incorporating details drawn directly from his signature artistic style and characters.

“I Want My Hat Back” is one of those rare books children ask to hear on repeat, and parents are happy to read again and again. It really captures what we’re hoping to build through Hanna’s Bedtime Stories — giving families a reason to slow down and enjoy the bedtime routine together,” shares Kara Carter, Chief Product Officer at Hanna Andersson. “So, it was important that this collection felt like it belonged right alongside the book, and Jon’s involvement throughout the creative process made that possible. I’m so proud of what we created together because it gives families another way to enjoy a story they already love.”

“For my first book, I Want My Hat Back, I made endpapers whereupon the characters and plants tiled across the page against a soft background. What I was really doing, even back then, was wishing those endpapers were pajamas,” Klassen reminisces. “Book illustration has always been, at least a little bit for me, wishing I was drawing animals onto pajamas. Here, finally, thanks to Hanna Andersson, THE people who make pajamas, are some pajamas with my animals from I Want My Hat Back on them, and I couldn’t be happier.”

The deal was negotiated with Hanna Andersson on behalf of Jon Klassen via Cecilia de la Campa and Steven Malk at Writers House, and includes a collection of seven pieces:

• Kids Jon Klassen Bear HannaJams™ Pajama Set ($49)
• Kids Jon Klassen Rabbit HannaJams™ Pajama Set ($49)
• Kids Jon Klassen Rabbit HannaJams™ Short John Pajama Set ($45)
• Kids Jon Klassen Long Sleeve Rabbit Dress with Pockets ($50)
• Kids Jon Klassen Rabbit Graphic T-shirt ($34)
• Kids Jon Klassen French Terry Bear Sweatshirt ($55)
• Adult Jon Klassen French Terry Bear Sweatshirt ($79)
