Always reliable, great gear

I've ordered from Mad Water several times now, and they're consistently good. My latest purchase was a Waterproof Duffel Bag for a river trip. It arrived in about 4 days, which is standard for them. The quality was just as solid as the Tactical Waterproof Backpack I got last year. Everything stayed dry, as expected. It's why I keep coming back.

Got a new Waterproof Waist Pack

I just needed a small bag for fishing, so I grabbed one of their Waterproof Waist Packs. It was pretty easy to order, and it got here in like, 5 days, I think. Used it out on the lake last weekend, and it kept my keys and wallet dry, which was the whole point. It's comfy enough, didn't really notice it much. Pretty happy with it, seemed like a good little purchase.

Good bag, minor shipping issue

I bought a Submersible Backpack from Mad Water for kayaking. The bag itself is excellent; it kept all my gear completely dry even after a capsize. The materials feel really durable. Shipping took about 6 days to reach me in Arizona, which was a little longer than I hoped, especially since I paid for standard shipping. Customer service was responsive when I inquired about the tracking, so that was good. Overall, a solid product and experience, but delivery could be a touch faster.

Good value for a Dry Bag

I was looking for a new Dry Bag for camping and found Mad Water. I signed up for their newsletter and got a 10% discount, which was nice. I ended up getting a Heavy Duty Dry Bag. Shipping was free because my order was over $100. It arrived in about a week. The bag seems very well made for the price I paid. I compared it to some other brands, and this felt like the best bang for my buck with the discount. It definitely felt worth the purchase; my gear stayed dry on a rainy weekend trip.

So, if I buy a backpack and it's not quite what I expected, how easy are returns with Mad Water? Do I get a full refund or what's the deal?

B Betty 1 week ago

Yeah, returns were easy, did it last month. Just make sure it's within their window and in good shape. They processed my refund pretty quick.

L Leah Wright 1 week ago

I think you just gotta contact them for an RMA and send it back. Haven't had to return anything myself but their policy seems pretty standard for online stores.

Hey, thinking about grabbing one of their dry bags for an upcoming kayak trip. Are these things really fully submersible? Like, if my kayak flips, my phone's not gonna be toast?

J John Jones 1 month ago

Yeah, they are. I took my duffel on a white water rafting trip and it got totally submerged for a bit. Everything inside was bone dry. Just make sure you roll the top correctly.

I've heard good things about the submersible aspect. I think some of their bags are rated for actual submersion, not just splashes. Good peace of mind for sure.

Anyone know how long shipping usually takes for Mad Water? Need a new backpack before a camping trip next weekend to Denver, wondering if I'll get it in time.

P Patricia Robinson 2 weeks ago

It can vary, but I usually get stuff within 5-7 business days to the west coast. Might be quicker to Denver. They do have free shipping over $100 though, that applies automatically.

Mine took about a week and a half for a duffel bag, but that was during a holiday sale. If you're cutting it close, maybe shoot them an email to see if they can give you a better estimate for your zip.

How do these compare to like, Yeti Panga bags? Price difference is pretty big, wondering if Mad Water is just as tough for fishing trips.

H Hannah J. 1 month ago

I've used both. Mad Water holds up super well, especially for the price. Panga might feel a bit beefier, but I haven't had any issues with my Mad Water gear failing. It's a solid alternative.

For fishing, Mad Water is totally fine. I think some of their gear is even more specialized for that. You're mostly paying for the brand name with Yeti, IMO.

Just found a 10% off coupon for signing up for their newsletter. Can I use that with the free shipping deal if my order is over a hundred bucks?

J Jason Turner 1 month ago

Yep, you can definitely use the newsletter discount AND get free shipping if your order qualifies. The free shipping just applies automatically once you hit the amount.

T Tim P. 1 month ago

I think you can only use one coupon code per order, but free shipping usually isn't a 'code' you enter, it just happens. So yeah, should work fine.
