Customer photo review of 30L Waterproof Dry Bag Backpack with extendable bottom compartment

My husband and I did a lot of research on dry bags before buying this one from Platinum Sun. We will be in the Dominican Republic for 3-weeks in December 2024 and plan to use this bag for multiply activities such as: hiking (and sliding down) the 27 waterfalls, kiteboarding, kayaking, and SUP. No other bag we considered had such great features. When we received our dry bag backpack we appreciated how well made and sturdy it is. The wet bag area at the bottom is a super bonus. We are so happy with this purchase.

Fishing trips just got better with this dry bag. It holds my tackle, snacks, and extra clothing, ensuring everything stays dry. The netted side pockets are perfect for storing bait or a water bottle. Ususally we have 3-4 same drybags on our boat. I wish they came in more colours so we can know whos bag it is. I think it's one of the best drybag for boaters on the market these days.

Customer photo review of Waterproof Dry Bag Backpack with extendable bottom compartment

I do,'t know what I did before I got this bag as a gift!!! I didn't know I needed it so badly. It is so comfortable to put your wet wetsuit and bootie in the lower compartment - and you don't worry about rolling it in a towel, bagging it in a plastic bag and squeezing the water out of it and it still makes wet all your dry stuff. This separate pocket is just what all of us need!

Customer photo review of Waterproof Dry Bag Backpack with extendable bottom compartment

This bag is indeed a game changer, I've had A LOT of different bags over the years. Using it for my scuba gear for shore diving as well as boat diving. I fit a changing hoodie, pants, thin hoodie, tee-shirt and workout bra in the bottom dry pouch. In the main bag, my BC, reg, booties, short fins, hooded vest, go pro and flash light. The side pockets hold a large 32 oz bottle of water each (with length room to spare). The front zip pocket, under the mesh, protects my phone from water and rain and sun and is hidden from view. The inside zip pocket holds my wallet, hidden away as well. All this while still allowing proper top closure. The shoulder straps are comfortable and the hip strap is adjustable to almost any size. This bag is narrow, so when wearing its not taking up too much space in crowded areas like a ferry or a queue. It looks as good as it functions. Even with all the weight, it is comfortable to carry! A MUST for anyone with any kind of gear that needs to be mobile. Do not hesitate to purchase, this is THE bag.

Customer photo review of Waterproof Dry Bag Backpack with extendable bottom compartment

I wholeheartedly endorse the Platinum Sun 30L waterproof dry bag! I'm a passionate kiteboarder and spend a lot of time at the beach and traveling. I've been on the hunt for a dry bag that combines versatility with external and internal pockets that many others lack. Not only is it a stylish bag, but it's also incredibly rugged. The bag rolls down and snaps together securely, keeping out sand and water. What's more, the netted side pockets are perfect for holding water bottles, and the exterior mesh is handy for my wet bathing suit and rashguard. The corded exterior is a bonus for carrying towels or other beach essentials. This bag also shines on hikes and other outdoor activities. The fact that it's a backpack makes it versatile for various outdoor pursuits. I'm looking forward to testing it on a long downwinder. It's a fantastic waterproof dry bag, and the price is unbeatable!

Store owner replied: Hi Jason, so happy the bag worked out for your family adventures! 😊 That wet clothes pocket really comes in handy, doesn’t it?

This dry bag is a versatile gem! I take it kayaking, and it never disappoints. Thanks to the corded exterior - I can easily buckle it to my kayak. It easily holds my camera, snacks, and spare clothes. The separate wet compartment is genius - my wet swimsuit doesn't dampen the rest of my gear.

I've long admired the stylish appearance, robust construction, and flawless functionality of Platinum Sun products. Their new Blue Adventure Dry Bag has left me in awe. While I loved the performance of the original adventure dry bag, there were times when it felt a tad small. They've truly outdone themselves with a 40 L capacity, additional pockets (including some secret compartments), and even separate wet and dry areas to handle real-life adventures. Whether it's a day at the beach, a deep free dive, a picnic, an epic Kiteboarding session, or a thrilling day on the snowboarding slopes, this bag has you covered. It's ready to tackle life and adventures with the same intensity as you do!

I love this bag. I work on boats every day, and had been looking for a good dry bag. This one is perfect! My favorite part is the separate wet compartment at the bottom. I put my wet towels or bathing suits in it after work and it keeps everything separate as stated. Definitely recommend!

This dry bag boasts a large capacity and comes equipped with backpack straps. It's perfect for trips to the beach or outings on a boat. The separate pocket at the bottom is handy for storing wet clothes and keeping other belongings dry. There are also plenty of additional pockets. My only gripe is that the waist straps are too small to buckle around my waist (38-inch waist). Aside from that, it's an amazing bag.

I bought this for Cross Country and some Downhill skiing. I also plan to take it on a beach trip. It safely stores everything I need, and it's easy to carry while keeping things dry. I'd recommend buying two if you don't want to end up carrying everyone else's items.

Store owner replied: Thank you for your review of our bag! It means a lot to us, and we're glad that you've found the bag to be useful for your water sport activities. Thank you for your support.

As a scuba diver, I needed a bag for my diving trips. I like this bag, but the waist strap is designed for smaller waist sizes, so it may not be suitable for those with larger waistlines. If you don't care about the waist support (which we don't need in most of the cases) - that wouldn't be an issue, the bag is perfect other than that. 4 stars just because of this issue. The bag does an excellent job of keeping water out and has a handy 'wet pouch' at the bottom. it's a good bag.

I'm a professional beach enthusiast, and this bag has taken my beach game to the next level. After living in the Virgin Islands, I learned the advantages of using a dry bag as a beach bag. It keeps things dry during unexpected summer showers and prevents sand from invading your belongings. We did a lot of boating and used to tie up to mooring balls and swim to shore. A dry bag was essential for that. But for everyday beach trips, this bag is a game-changer. Most dry bags lack extra pockets or storage spaces, and that's what sets this dry bag apart. I keep my snorkels in the bottom compartment to keep them wet without soaking everything else in my bag. I used to have to bring two bags to the beach for this, and now I only need one. I prefer to snorkel in a long-sleeve shirt, and this bag conveniently accommodates my wet shirt. There's also a mesh pocket for my sunscreen, making it easy to grab and reapply. Plus, there's another zippered pocket behind the mesh where I keep my phone and wallet. Lastly, the cup holders are a lifesaver for our water bottles. All these additional storage features make this dry bag a cut above the rest. Don't hesitate, just buy it.

I've used this bag on two canyoning trips, and it left all my friends envious. The outer pocket is perfect for a CamelBak, something most dry bags don't accommodate. It's a roomy backpack that can fit everything I needed. During canyoning through waterfalls and swim-throughs, it kept my belongings dry. The extendable bottom zipper compartment was a savior for my wet gear, ensuring everything else stayed dry inside. This bag is simply awesome!

Great dry bag! It has a lot of room in the compartment and all my stuff stayed dry on the boat. However, I do wish the bottom compartment for wet items was a little larger so I could fit my winter wetsuit in it.
