About the NANUK 903

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.


Automatic Pressure Release Valve

Automatic Pressure Release ValveKeep 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.

Stand out with a unique design and color selection.

Design & ColorsStand 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.

Needed a small, portable, waterproof box for heirlooms and documents during a move - perfect fit!

Roberto Ledesma
Tuff little case

Tuff and strong case, excellent for what I needed.

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

This is a well built case, with a great price. Will be buying more

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.
