Great product, even greater interaction
I original bought a bag from KNKG that ended up having a tear in the top pocket of the bag. After reaching out to customer service and interacting with Taylor, I was able to get the Core Backup Medium 25L, which has been fantastic for my workouts! I couldn’t be more grateful and excited to use it for a long time!

Great bag and amazing quality!
I bought this for my husband and he loves it. He needed a bag with a lot of space for work laptop and workout gear (shoes, lifting belt, clothes). He loves this bag. It fits everything he needs and the quality is amazing! You can tell the bag is well made and will last a long time!
