Paul Verroche

Great service and quick delivery. Use these boxes to setup batteries on my kayak.

James Prier
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.

Dave Melville
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.

Steve Mitchell
Quality Case

Price is right, and equal quality to Pelican. I buy these for all of my companies electronics.

Mrs. Jones

Peter Qumaluk
Great value

More than i expected

Jeff Rowell


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!

NANUK 903 Features

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!

Lightweight NK-7 Resin

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

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.

NANUK Lifetime Warranty

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.
