Review on COR Surf Waterproof Dry Bag Backpack with Padded Laptop Sleeve 25L & 40L Heavy Duty Roll-Top Pack: The Ultimate Waterproof Backpack for Outdoor Adventures by Joz Lowe

I ordered a 25L bag. The material appears to be waterproof and of good quality. It has enough space for what you need. If you take it on weekend trips and take a lot of things with you, you can take more with you. I ordered it for school and occasional beach trips and hikes. It does have a laptop compartment, but my Lenovo 15.6 feels a little big for it. It doesn't fit right. If you have regular laptop or Mac laptop, it will fit much better. However, it still holds it in place and gets the job done. I really like how you can roll it up and pinch it. As long as I like it! It is ideal for beach walks and outdoor walks. It's raining today so I'll have to check.
