Not for big chested females
Can for sure say this wasn’t 100 meant for ladies with bigger chests, it fits odd haha. But I still love it! Lots of compliments and the app is easy to use too.

Hands down the coolest thing I've ever seen..
I recently Received. the Grimace LED Backpack and I've got to say, it's definitely an attention-grabber! The LED lights make me feel like I'm walking around with my own personal disco party. Not only does it look cool, but it also adds an extra layer of safety when I'm biking at night.The hardshell design is perfect for keeping my half-face motorcycle helmet secure, and the small size is just right for my needs. The backpack is also roomy enough to carry my essentials without feeling bulky. The black Grimace Backpack looks sleek and goes well with my gear.Overall, I'm very satisfied with this backpack. It's both functional and fun, and I've had several people ask me where I got it because they want one too. If you're looking for a unique and practical riding backpack, the Grimace LED Backpack is definitely worth considering!

What an Idea!!
I recently got the Grimace LED Backpack and it has exceeded all my expectations. This hardshell bike helmet riding backpack is perfect for my half-face motorcycle and ebike helmet. The compact 17-inch size is ideal for my needs, and the black color looks sleek and stylish.The LED lights are a standout feature, significantly enhancing visibility and safety during night rides. I feel much more secure knowing that other drivers can see me clearly. The backpack itself is very well-constructed, with a durable hardshell that protects my gear without adding too much weight. The interior is spacious enough to carry all my essentials, and the design ensures everything stays in place, even on bumpy rides. The straps are comfortable and adjustable, providing a snug fit that doesn’t shift while riding. The only thing I don't like about it is that it must be connected to a battery pack. I think they could have integrated a chargeable battery or allowed AA style batteries to run the LEDs. LEDs are not that power hungry which would make AA batteries much more suitable. I still won't hold this against this product as it does what its supposed to do well.Overall, the Grimace LED Backpack is an excellent investment for anyone who rides a motorcycle or bicycle. It combines safety, style, and functionality perfectly. I highly recommend it!

Practical and Attention-Grabbing Biking Backpack
Sturdy Design:I recently started using the Grimace LED Backpack for my biking commutes, and it’s been pretty useful. The hardshell design is solid and does a great job protecting my gear. The Sea Heart design adds a nice touch and definitely makes it stand out.App Functionality:The app that controls the LED display is straightforward and works well. It’s a nice feature for adding visual warnings to those behind me, which is a big plus for safety. Being more visible on the road is always a good thing.Battery Requirement:One downside is that the backpack doesn’t come with an internal battery. You have to provide your own, which can be a bit of a hassle. Once you have a battery hooked up, though, the display works perfectly fine.Durability Concerns:The shape of the backpack means the display can get scratched easily if you’re not careful. I’ve noticed a few scratches already, which is a bit annoying, but manageable if you handle it with care.Overall Experience:Overall, I’m happy with this backpack. It’s sturdy and the LED display adds a layer of safety that’s hard to beat. Just remember to handle it carefully to avoid scratching the display and make sure to have a battery on hand.Final Thoughts:The Grimace LED Backpack is a good choice for anyone looking to stay safe and visible while biking. Despite needing your own battery and the risk of scratches, it’s been a solid addition to my biking gear. If you’re careful with it, this backpack is a great way to enhance your visibility on the road.

Sturdy and good storage. LED screen means higher visibility to other drivers!
Good quality, sturdy construction. The LED screen is nice and bright, which means that I am more visible on my bike. The app is easy to use. I get so many compliments when using the backpack. It does need a charging bank.

This is a blast!!! But check local laws before using!
I absolutely love this backpack, for added visibility for motorcyclists, it's a great concept.However, make sure you check you local traffic laws and make sure you don't use images or animations that will be too distracting or bright for other drivers. I got pulled over and ticketed for having a distracting light facing backwards that was deemed hazardous. The officer thought it was a cool concept, but told me to be careful about having animations playing and keeping brightness to a reasonable level.The backpack performs well enough, it seems to do a decent job of keeping water out, and the built in ozone generator is an awesome way to decrease odors inside of the backpack. The app is fairly easy to use, but the fact that it doesn't come with a power bank is a minor complaint.It has a pretty large carrying capacity and feels sturdy enough for what it is. Though, the straps feel less than awesome in regards to durability.
