This is a Nike skateboard backpack. Previously known as the SB RPM Backpack, it's a best-selling model from Nike, purchased in February 2025. I modified this backpack to hold two tennis rackets because I couldn't find a good tennis backpack. The design is not commonly seen on tennis courts, so people often asked where I got it, and it was well-received. **[This item has been modified for tennis racket storage]** The laptop compartment on the back had a mesh shelf a few centimeters above the bottom of the bag. However, when I put tennis rackets in, the rackets wouldn't reach the bottom of the bag, and the grips would stick out too far. So, I cut out this shelf with a utility knife and attached sponge cushion tape to the bottom to protect the racket heads (see photo 5). With this modification, two 100-inch thick rackets can fit. However, the zipper closes from one side, so the racket grips need to be angled slightly when zipping (see photos 1 and 4). ▼ Excerpt from the online store product description —— Nike Sportswear RPM Backpack (26L) ¥13,090 (tax included) <Features> Internal sleeve can store a laptop up to 15 inches.
