PowerClaw Superior Latching System
Close with confidence. Open with ease.
Ensuring that your smaller gear stays well protected from the elements, the NANUK 903 case's patented PowerClaw latching system uses compressive force and triple action to clamp your case tight. Integrated slide locks offer added security, preventing your case from opening during transport or if it’s dropped. The super tough nylon construction and stainless-steel hardware ensure that your important items stay safe in your NANUK waterproof case no matter where your journey takes you.
IP67 Waterproof & Dustproof
Go where no case has gone before.
NANUK protective cases were primarily designed for front line protection, search and rescue missions, first responders, military, industrial, marine and diving uses. The professionals that rely on NANUK cases require a reliable, waterproof solution which resists deformation and fatigue. NANUK ensures a long-lasting, watertight seal - nothing gets in – nothing!
Indestructible & Lightweight NK-7 Resin
Get High-Impact Protection with a fraction of the weight.
Impact-resistant, lightweight, and armed with NK-7 resin body, the NANUK 903 protective case is designed with rounded corners, thick, strong walls, and oversized details. No matter what nature throws its way, NANUK is built to survive. This NANUK is shock-absorbent to prevent damage to the case and, more importantly, to the valuable contents.
Design & Colors
Stand out with a unique design and color selection.
Rounded corners and chamfered edges merge with strong character lines to deliver a design that is as sleek and modern as it is tough and reliable. Be it for aesthetic preference or more practical purposes, color choice is an important feature for many NANUK users - choose from up to nine colors depending on the case. Color options range from emergency red to military olive, meaning that you can blend in or stand out, whatever the task entails.
Automatic Pressure Release Valve
Keep your case from sealing shut. Automatically.
Changes in altitude, temperature, humidity and geographic location create a “vacuum lock” which can effectively seal a case shut. NANUK's integrated auto-pressure valve equalizes this atmospheric pressure difference. Using state-of-the-art technology, the micro vent allows air to pass through while preventing water from entering.
Guaranteed for life
NANUK cases are designed and manufactured in Canada and are tested in some of the harshest conditions, including our own backyards. Every NANUK case comes with a lifetime guaranty so that if there is ever a problem with your case it will either be repaired and returned or replaced.
Customer ReviewsWrite a review
I bought this case for a vaporizer with many glass parts. It is nice to not have to worry about breaking my things because it is in a sturdy little case surrounded by plushy foam specifically picked to keep my items safe. Thanks! Great customer service too!
Amazing case, great quality and looks. Fits a digital camera and accessories well.
Awesome product. Use it every day on the job
I really hate writing reviews but now and then you find a product that stands out above the rest. I use these cases to house my camera gear and gimbals that I use in the construction field daily and I’m not really easy on equipment. I bought bought about 15 of these cases over the last three or four years and if stood up to all the abuse I can give them and not only that what’s in them stays in perfect condition.
Needed a small affordable case to house my custom built 18650 battery for field charging and this fit the bill perfectly.
I am very pleased with my 2 purchases of Nanuk cases (905 and 903). Looks good and secure - however not "tested" yet how waterproof they are. In may case, yours sizing is better then the competition. I wish 905 have kind of snags on ribs below a hinge - I can secure it on canoe or elsewhere. Also - internal padding (in 905) is not to flexible- in the sense of elasticity and ability to be arranged. Please, make also something for modern phones - with 6.5+ display!
customer service very helpful and the product is very good for sealing and maintaining the humidity
Great looking box, excellent quality & perfect for my desired application. Price point was great!
