The clothing/fashion brand Hypeland did a Sonic collab in 2024. They produced A LOT of shirts for it, and then released multi shirt photos of everything. Rather than splitting them all up into smaller images to see 3 tees at a time, this page has their original size (very large) images with all of the shirts so you can just see everything at once. You'll probably need the left/right scrollbar as well on this page.
These first 9 tees show a nice variety and nothing here is tacky on purpose (unlike StrayRats) The triangle shape is 3 H letters and it is their logo (so, behind the 'die Sonic') Rouge gets either pink or black to choose. The Metal Sonic "There can be only one Sonic" is from Sonic CD (the slogan probably also is?) Each item is co-branded with the Hypeland word somewhere on it. Look for the logos on the sleeves too sometimes.
9 More Hypeland tees, and 9 more with quite nice variety. Styling their logo like Green Hill, including Cream & Cheese, and having an Eggman solo tee are all very good to see. The Eggman one is written in Japanese though so you can't tell what it says. Amy's shirt says "Piko piko hammer". Now, modern Metal Sonic appears, and Shadow gets two shirts as well to choose. Each one has a good and different look.
Wow! Twenty Five items! Hypeland is really delivering on the hype for Sonic clothing with this big set of stuff. And this time, it's not just tees. You can see they have a Letterman Jacket, zip front jacket, 3 sweaters, sports jersey style, 7 hoodies, and the rest are tees. That half/half Sonic vs Metal Sonic sweater sure is an interesting design that hasn't really been done much before. Uncommon themes include Angel Chao, polygon components for Neutral Chao, DJ Sonic, Super Sonic, more Dark Chao stuff, Silver (as line art) and even one starring the Chaotix with their old logo, it looks like.
