Med kit for Overland rack

Currently using this as an exterior mounted med kit on an Overland rack for my Jeep gladiator. Crazy well built, the latch system is bar none the best latch system available on any hard case on the market, it has absolutely zero sign of leaking even in a heavy downpour. Will be buying more of these soon, also running some of the rifle racks on the top of my rack. Nanuk is the way to go if you're looking for a hard case! A++

My fifth Nanuk case

Nanuk is my go-to case for anything I need to protect. So many sizes, options, colors, I can always find what I need.

Have Bow Will Travel

Spent a lot of time researching bow cases for my new bow. Nanuk stood out from the rest in many ways. I know my baw and all its parts will be safe. My husband went with a lesser case and his sight broke durning travel. Worth every penny!

The best storage solution for my XMR!

I needed a protective case to keep my phone, wallet and keys safe while ATVing and the 903 fit the bill. The yellow is vibrant but unfortunately doesn't match the yellow on my 909 GoPro case. The colour will fade as it did on both my 909 (Yellow) and 915 (Orange) cases. But cosmetics aside, this is the only brand I trust with securing my valuables, period. My 903, 909 and 915 cases have been put to the test while being strapped to a CanAm Outlander XMR and has survived snow, mud and has been frequently submerged underwater with zero issues. *Note, My 903 and the 909 both fit great in the rear storage compartment of the Outlander!

Great case, misleading website

The case is excellent. Superior to competing waterproof cases and less expensive. Very well made. However, the website should clarify its claim of FREE SHIPPING by adding in same size letters ON ORDER OVER $200. Also shipping to Vancouver took 1 week not 3 days.

Nice watertight box

Bought this to fit a new larger phone. Seems well made. I have used it a few times on kayak trips. It does not have a fixed loop for securing it into a whitewater boat--a sling through the handle seems OK. The foam insert I was sold does not fit well. I will buy sheets of closed cell foam and make a padded liner.

Secure and waterproof meds container

Perfect size for my meds while on multi day kayak trips. Better quality than cases from other manufacturers, fair prices, amazing customer support, and made in Canada. I own 7 Nanuk cases and I never worry about wet or damaged gear.

Piece of mind

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!

Can't kill them

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.

Perfect for organizing, protecting and carrying your most important smaller gear, the NANUK 903 waterproof hard case is impenetrable and indestructible with a lightweight, tough resin shell and double side-mounted PowerClaw superior latching system.

With Nanuk's exclusive locking and latching system, your case stays shut and secured until you are ready to open it.
Waterproof, dustproof, and indestructible, the 903 is ideal for batteries, lenses, smartphones, flash drives, hard drives, small cameras, microphone systems, small pistols, medical devices, first aid kits, emergency gear, sensitive instruments, electronic equipment or any other smaller personal or professional equipment that might need superior protection.

The NANUK 903 protective case comes with a soft grip and ergonomic handle to make it easy to transport.
It also features stainless steel hardware and integrated handle stay to keep the handle out of harm's way when traveling or during shipping. This transport case is also equipped with an automatic pressure release valve and an integrated bezel system to accommodate custom panels without needing to drill holes, so the case stays watertight.

This MIL-Spec injection molded case is backed by a lifetime warranty. Inside, products can be secured with cubed foam, custom foam or the case can be purchased empty.

Features

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.

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.

Indestructible & Lightweight NK-7 Resin
Get High-Impact Protection with a fraction of the weight.
Impact-resistant, lightweight, and armed with an NK-7 resin body, this NANUK 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.

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!

PowerClaw Superior Latching System
Close with confidence. Open with ease.
Ensuring that your smaller gear stays well protected from the elements, this NANUK 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.
