Overall, pretty solid for what it costs. The materials feel durable and well made. Waterproofing does the job kept my stuff dry in the rain. The design is simple and practical too. No complaints so far

Do not buy anything from this company. The bag is poor quality. The seams split open just by rolling the top and trying to remove the air. When I contacted the company they told me to get it repaired locally.

DO NOT BUY THIS BAG! Its about as big and a drawstring bag on the inside. You better love it on first site because if you even remove it from the original plastic they wont let you return it. If your bag is defective they pretty much just says lol sucks for you, you took the hang tag off. OFF OF A BACKPACK THAT YOU WONT EVEN KNOW IS DEFECTIVE UNTIL YOU USE it! Customer service is actual garbage and takes 2-4 business days to respond.

Terrible customer service and bag is not what they company markets. I ordered one of their bags and my laptop does not fit the sleeve. Also the bag itself is not comfortable to wear. I tried to get a refund and the company refused to make things right. Instead they wanted to give me a credit for items that I do not need nor want. Owner/founder is very rude and puts words in your mouth. Very unprofessional. DO NOT WASTE YOUR MONEY!

They say 2 to 4 buisness days US delivery, well it's been 17 days and counting, package went from Fort Worth Texas to Des Moines Iowa to Las Vegas Nevada, now no clue where it is, company said would get back to me in 24 to 48 hours that would make it 19 days, why should they care, already have my money,

Not a good product - sorry it’s just not. And the business is really scammy.
This ships from China, and it has a 15 day return policy where buyer pays return shipping - so heads up.
The website says 2-4 days shipping to USA, in my experience this is a lie. In my confirmation email it said 8-12 days for shipping. This was also a lie. It came after a month. So be aware of the timing.
This bag does not feel like a true dry bag, it doesn’t have a solid top seal (it’s a Velcro top) and the rolled material at the top leaks because I couldn’t achieve a water proof seal with only Velcro and a couple rolls. Most dry bags have a flexible plastic piece that gets rolled up and allows the top to seal tightly, this is NOT that. So, I would not take it swimming. Which is what I wanted to be able to do. I think it’s dangerous they advertise this bag as a dry bag - it’s water RESISTANT it definitely does not seem to be water proof. Mine was definitely not waterproof.
They advertised free extras - like key-holders. Those never showed up.
The shipping from China was in a plastic bag, like thin plastic. They should consider a box or at least more secure plastic packing because it’s going to get damaged, mine was damaged. And missing any key holders they may or may not have sent.
My backpack had a hole in it, so after all this and being excited and totally missing Christmas (this was a gift) it also missed New Year, has a hole in it, isn’t a true dry bag, and it’s missing my freebies.
The material feels good, it’s like thick rubbery feeling with a fiber-y substance inside, but obviously not that tough because it somehow got pierced in shipping. I wish the clips were stronger and tougher feeling too. They are thinner than I expected and feel like they are going to break. At this price point I feel like the clips should be better quality.
Maybe I’m being unreasonable, but for $110 bucks I expect something better than decent quality and resembling what was advertised and responsibly packed and shipped.
I’ve reached out to customer service (and did several times earlier because tracking was pretty useless), they have a lot of excuses and nothing that helps me feel better, I want to feel better about this bag but… so far company and product are sub-sub-par. Like I can’t recommend them or the product.
My advice, if you are considering this over-hyped bag, don’t take the risk. I do not recommend the company Expedition-Unit, or the Project 8020 backpack.

These people are crooks I’ve order 2 bags and 2 carabiners, they were supposed to be delivered within 22 days. I did not receive my order and now they are doing everything in their power to not give me my order or money back bringing every excuse in the book and not getting to the point terrible business.
Update: after finally coming to agreement we settled and business was done.
