When exploring the outdoors, it’s important to keep your devices protected from the elements, especially if you find yourself around water. Whether you’re hiking, camping, or doing water-related activities such as fishing, kayaking, or boating, moisture and water damage can ruin valuable electronics like your smartphone or even more sensitive gear like a camera. One of the best ways to keep your tech gear protected from excessive humidity and water is to use a dry box. Unlike standard storage options, which may fail when put to the test of getting wet, a dry box provides a sealed, humidity-controlled environment, meaning it can effectively keep your belongings safe from moisture, dust, and corrosion. So, if you’re looking for a dry box that’s easy to carry and built to last, the Evergreen TOUGHBOX Seahorse 57 is a great option.
The Evergreen TOUGHBOX Seahorse 57 is a compact, medium-sized dry box which has an impact-resistant polycarbonate construction with an IP67 Waterproof Rating that can keep your items protected such as your smartphone, wallet, keys, and other devices, plus it can also float when storing under 5 lbs. of gear. It also features a TwistLock Latch locking system that provides an airtight seal with the ability to key lock the case, up to 10 lbs. of storage capacity, and also comes with a removable Rubber Boot liner that offers additional protection and shock absorption for your items, and a silicone mesh for securing small valuables like cords and bank cards.
Built to withstand any adventure, this sleek dry box is the ideal storage solution for keeping your items safely stored while exploring the outdoors, making it a great addition to any outdoor gear setup.
Now, let’s have a closer look at the Evergreen TOUGHBOX Seahorse 57 and go over all the distinct features this dry box has to offer you.
DESIGN & SPECS
Starting with its size, this dry box has a compact form factor, measuring just 9.5 inches long by 5.8 inches wide by 3.8 inches wide. This dry box is also rather lightweight, weighing just 2.31 lbs. when having it empty.

Its sleek dimensions also make it easy to fit inside most backpacks, and the case can also be comfortably carried by hand. You can also attach a lanyard onto it to latch it onto your wrist, to the outside of your hiking backpack, or other pieces of outdoors gear.
What’s more is that the case is also ATA 300- and TSA-compliant, so you can go through airport security with it.

The Evergreen TOUGHBOX Seahorse 57 also sports a cool “outdoorsy” design, with its body coming in a solid color, for which you can choose from multiple color options.
More importantly, this dry box also packs an extremely rugged construction made to withstand MIL-STD 810F standards, as its hard case is built of 100% high-density pure polycarbonate, which makes it impact-resistant and nearly unbreakable.

Its outer shell is also rated to have a IP67 Waterproof Rating, which qualifies it as being dustproof, rustproof, and also waterproof down to a depth of one meter for up to 30 minutes.
In addition, the Evergreen TOUGHBOX Seahorse 57 also comes equipped with a TwistLock Latch locking system, which provides an airtight seal for all your belongings.

The case’s locking mechanism offers three different levels of security. Its first level of security consists of a waterproof latch that firmly secures its front-lock’s o-ring and doubles as a flip latch pressure equalization system that automatically equalizes the pressure inside it.
To lock it tighter you can either lock its TwistLock Latch by hand, or ultimately by using the included locking key for extra security.
As for its storage capacity, know that this dry box can store up to 10 lbs. of gear. The case has enough space to store several of your personal belongings, including your smartphone, as well as your wallet, car keys and house keys, and can even fit an action camera (such as the GoPro or the Insta360) inside it.
Furthermore, the case is also rated to have a buoyancy up to 5 lbs., meaning it can float when storing under 5 lbs. of gear.

For the dry box’s interior, you can choose having it empty or having it come with a removable Rubber Boot liner that gives your gear first-class cushioning for additional protection and shock absorption.
Additionally, the case’s interior also comes equipped with a silicone mesh under its lid that can be used to secure cords, bank cards, keys, a pair of earbuds, or other small valuables.
In alternative to the Rubber Boot liner, you can have the case’s interior coming with an AccuformFoam liner made of a low-density foam material that securely cradles your equipment, or a PROFoam liner made of a specialized foam that offers premier storage customization for varying depths by using with a knife and maintains shape over time.
