IMPORTANT NOTE: In our efforts to reduce waste and use materials that would otherwise end up in landfills, the tank print is a random print and does NOT match the diaper print. We can not exchange tank prints unless there is a product defect. Thank you for your understanding and for helping us strive toward greener earth for all! 🌏

Hidden Secret Weapons

Though it may not appear as formidable as its name implies, The Tank is packed with plenty of hidden features to help it win the war on wetness. A battle-tested recipe of charcoal, bamboo and our Bamboo Stay-Dry Liners aided with PUL, join forces to form the ultimate wetness-fighting machine.

Bullet-proof leak protection

Okay, so it isn’t actually bullet proof. BUT it is lined with PUL, making it waterproof. This means that moisture stays in the inserts, letting you reuse covers and ensuring that there is no unwanted seepage. The Tank is like a diaper within a diaper.

Win the war on stains

We all have haunting flashbacks of that stain we just couldn’t defeat but with the Tank you need not worry. All front-line fighting materials that face the business end of your baby are dark coloured to hide any battle scars.

Feeling out-gunned by your baby’s ability to fill a diaper?

The best combo for leak-fighting, standard issue.

A go-to strategy for many Lil Helper veterans was to combine a small charcoal insert with a large bamboo insert, for maximum leak-fighting efficacy. It works amazingly well because the fast-absorbing charcoal insert quickly grabs and wicks away moisture. It then transfers it to its thirsty bamboo brother-in-arms, who is better equipped to shoulder the liquid load. The problem is that this mix and match approach leaves mismatched inserts. We believe in leaving no man (or insert) behind, so we have made this winning combo standard-issue from here on out.

Who says you can’t be both a fierce warrior and fashion monger?

Fierce and funky

At Lil Helper, we are suckers for any opportunity to rock a great print. That’s why we are pumped about the cute PUL prints you will find on the bottom of each Tank insert set. Plus, like any good soldier, these bad boys are all about the element of surprise. You will get a random print with every set.

K, cool, but why “the Tank”?

Because they are the best weapon for freedom-fighters doing battle with pooplosions, diaper leaks, and rashes.

The team at Lil Helper are a generally pacifistic bunch.

As loveable tree-huggers, we shy away anything more violent than an aggressive handshake. But what else would you call an insert that can hold 300 ml of moisture without breaking a sweat and be hardy enough to bear year over year of abuse - The Tank!

The tank will let your baby sleep for 12+ hours without a change and will do it while looking pretty!

When you are eyeballs deep in the trenches of parenthood things are chaotic but until the ceasefire comes, enjoy every moment of both the struggles and the snuggles and know that Lil Helper has your six both on and off the battlefield.

Pretty Dang Good!

I bought a couple sets of the Tank Inserts to try for our heavy wetter and they are perfect during the daytime after a big feed. We found that she still leaks through the sides during overnight usage so we'll have to try using a booster perhaps for those times.

Game changer!

When I started cloth diapering I was using a 2nd hand lil' helper collection I had purchased from someone online. They had an older version of inserts that they came with. I wanted to cloth diaper so badly, but found my heavy wetter was going right through them, even leaking through the cover. I was a little discouraged but still decided to purchase a couple new diapers because of the cute prints. Well when they arrived with the tank inserts, it was like the angels sang 😇 and cloth diapering became so much easier!!! We can now use the same cover for a few changes and we never have leaks anymore. I have replaced the old inserts with these and it was worth every single penny. By far, cloth diapering and these tank inserts have been the best decision I have made as a new parent!

Crazy absorbent! My guy is an extreme heavy wetter. At night we do a large tank, a small tank, a booster, and another small tank. We can get about 9-10 hours depending on how much he eats at night (he usually soaks through a disposable in 5-6 hours at night).
