What customers are saying about us…


We bought the equalizer mask and fins package for lake and river snorkeling and it’s amazing. As soon as I submerged my head I was in a whole new world. I have never experienced such an immersion into the underwater world before (with normal snorkel gear). The equalizer mask is crystal clear, no water ever gets in (even when I dive, do summer saults, jump in off a rock) and being able to equalize my pressure by plugging my nose is awesome. I love breathing freely through my mouth and nose. I’m just really impressed and love my mask. The flippers are really nice to. They fit great.

Great design

This is the best snorkel mask I’ve ever had. Very comfortable on face, easy to breathe. I am not a good swimmer, it makes me feel safe and enjoy snorkelling without distraction. Thank you ninjiashark.

Best snorkel ever!!

Got one of these for me and my 7 year old daughter for Xmas. We’ve used them twice already and love them!! So much easier to breathe, can see so much and just makes the whole snorkelling experience better! Would highly recommend!

Package: Dry Snorkel (Set + Fins + Bag)
Mermaid M. (Townsville, AU)

While travelling in Timor leste l met a fellow snorkeller. We snorkelled for 10 days together the food was shit but the water was stunning. The friend was using Ninja Shark fins and mask mine were steaming up, letting in water and heavy. On arriving back in Australia l ordered straight away.
I was a little bit anxious on receiving my order as the mask was quite different to my old one and the fins were short and adjustable ( l wanted them to be my size ! ) well to my luck the weather was beautiful ( yes mid winter in Mackay ) and perfect for boating so off we scooted to Cockermouth ( don't laugh it's a real place ) jumping in and WOW I'm now a mermaid 🧜‍♀️ the mask and fins felt like part of me. I actually cried as not only was the equipment allowing me to explore as l wanted but the reef was STUNNING. So lm indepted to Ninja Shark for making me the mermaid l always aspired to be 🧜‍♀️

Took it to Tahiti

I wasn’t quite sure about getting a full face mask but bought mine (Electra package) before a trip to Tahiti which we got home from yesterday - absolutely LOVED it!!! I’ll be getting one for my wife before our next trip to a similar destination. BTW I make LOTS of crazy videos with lots of toys. YouTube video placeholder
Life changing

I do love my full face snorkel.. the freedom of nose breathing under the water.. the meditative and relaxative effect of this snorkeling is unexpected and great. Fits so well.. comfy to wear for long time.. highly recommend

Super quality & fit

So happy we got Ninja shark, perfect for Great barrier reef snorkel day.
Flippers, mask, dry wallet, carry bag (good quality bag), anti fog spray, happy days.

Ninja Shark Kids Mask

We recently brought the Ninja Shark Kids 3-11 Mask + Fins + Bag package for our 7 year old who absolutely loves it! Will be buying three more for the rest of the family. 😊

Even better than expected!

I saw the kids full face snorkel masks online, and thought they looked pretty cool. I ordered two for Christmas, for my 3 and 6 year olds. Wow, did they have a great time with them!

I wasn't sure how the 3 year old would go with it, but he was comfortable in it almost immediately, and spent hours swimming around and seeing a whole new world of underwater scenery.

They were easy to fit, zero issues with them staying on. No leaks or fog.

They can't wait to get back to the water!

Highly recommend this product :)

Great way to swim

I have NEVER been able to snorkel but love swimming. These full face snorkels are an absolute game changer in my life. Now I try to swim around 5 kms a week in the local pool. The Ninja mask makes it easy to do laps. I’ve been using the Ninja Shark for a quite few years and find the new Electra the best full face mask ever. No leaks, no fog and really easy to use and great quality. I’ve noticed my regular chats with other swimmers at the pool have encouraged many of them to purchase one of their own. I’ve given my older models to my grandkids and they love them too.


I got one for the 3 year old and one for the 5 year old, I thought maybe the 3 year old would get the hang of it eventually but they both loved it and mastered it pretty quickly. We’ve only used in the swimming pool, excited to go snorkeling in the ocean soon. Great product.

Love it

Bought these for myself and my husband after getting the full face masks for the kids, and they were so good we’re getting them for the rest of the extended family for Xmas. The fact u can dive down and not get water down ur snorkel is a brilliant bonus! Makes our family holidays much easier and better without snorkel dramas!

This made our holiday

The product itself was amazing, but the service we received allowed us to get our 2 sets of masks for our cruise. We took them with us and used them multiple times for snorkelling on our cruise to Nouméa and New Caledonia. It was amazing snorkelling and being able to breathe easily, and the fins were the most comfortable I've ever used. I've got size 13 feet, and not only were they completely adjustable, but they were THE most comfortable fins ever invented. A massive shoutout to Colleen Zamora from your support staff who helped me out and made it possible to take our gear on holidays! Thanks Colleen!

<3 em

So, I had the old type standard snorkle set I saw the add on tiktok thought I would give it a go. ONG I love them!!! They are so comfortable easy to get on and off and very very good to snorkle with I can see perfect clear thru them and doesn’t fill up with water! A very happy camper

My kids love them

I’ve got three of these masks for my younger kids, however the oldest wants one too as the young ones rave about how good the are.

Summer Family Fun

Our Ninja masks have made snorkelling as a whole family very easy and enjoyable. The kids (and parents) find them super easy to use and have allowed us as a family of five to snorkel for longer than we ever could using traditional snorkel gear. I would highly recommend these masks.

Glad I have but haven’t needed to use .. yet

Great Mask

Love this mask. Kids find it so much easier snorkelling with the Ninja Shark. The snorkel mask is super clear and doesn’t fog up. The adjustable straps are great and easy to loosen and tighten. Very happy that we made the decision to get these for the kids.

A must for snorkelers!

Recently purchased the Equaliser Pro Mask, Finns and bag. 🤿 🐠🐡🐟🦈 Had an amazing time snorkeling off Fitzroy Island, the Pro mask allowed me to explore for over 7 hours. Higly recommend! Planning must next snorkeling trip! 🤿💦🌴☀️

Fantastic snorkel!

Our 5 year old has never snorkelled. Put it on and was snorkelling no problem straight away! Easy for him to put on and off by himself. We bought the full package with flippers (also amazing and he can put them on by himself) and the two wet bags. The foldable snorkel is so handy for storing while we are travelling. And the lifetime warranty gives us great comfort that we can use it for future trips! We are so impressed with this product I’m going to get mum and dad one too!
