Let your twin-turbo S55 engine sing with the Xforce VAREX™ Valve equipped exhaust system, specifically engineered for the BMW F80 M3 and F82 M4.

Love this bag!
Color: Green
I love this backpack! I had a messenger style bag before this one and when I would look for things, other things would fall out because it was one big pouch. This is so much better. I can fit everything I need in it and everything has a place. The zippers are not cheap flimsy ones. They will definitely stand the test of time. The material is awesome and is definitely water resistant. I got caught in the rain and my things were kept nice and dry. The style is so cute too! It’s my favorite color.

Comfortable,
Color: Brown
I love this backpack I thought I’d use it on vacation, thought am or using it everyday! It is so roomy, a couple of the compartments are empty! It’s great if you have any kind of back pain! I did buy a crossbody strap to use as an alternative. Great deal and well made

Easy to use, multi strap, everyday bag
This bag is super handy and feels very durable. I at first didn’t like the 3 types of straps included on it because it felt like over kill but I don’t mind it after using it regularly. I wish the long strap was thicker, more durable material but it does match the sewn on straps on the bag. The design is a bit bold for my taste but it is different, fun and unique. The canvas texture of the bag makes it easy to use everyday without concerns of excessive wear. It also has a large carrying capacity. I can fit tablet, phone, makeup, snack, large water bottle, wallet and more while still zipping at the top. I would have given 5 ⭐️ if not for the long strap which I don’t feel will last with heavy loading and daily use. And if you switch the strap out it won’t match the sewn on ones so that’s a bummer.

3.5 stars, really - not a bad bag
Okay, I like this bag. I will use it and I'm glad I got it. However... First of all, it smelled terrible out of the package. It's like a chemical smell and a rotten smell. That may just be the one I got. I let it air out by hanging it on our hall tree, and it has gotten better. The material is like a thin corduroy almost, which I like better than canvas. I also like how the decorative strap on the bag matches the handle straps. There is plenty of room in this bag, but it's not a bottomless cavern. So you can still find what you are looking for in it. You could use this for a laptop bag or professional bag. I will probably just carry it as a purse with certain outfits. I think the brown color goes with a lot, and the designs all work for fall.
