The Large Tank Insert Set (2 pk)

$10.00 +200pts

Looking to add some firepower to your diapering arsenal? Want to ensure that you are always packing enough heat to subvert diaper disasters? Meet The Tank. The poop-suppressing, leak-quelling, bomb-proof insert that will thwart even the most sophisticated battle-plans from your heavy-wetting little warrior.

2 inserts per set (both Large).







Upgrade your diaper arsenal

While you can buy complete (and completely awesome) sets of our Tank inserts, we don’t want your existing stash to go to waste. That’s why we are offering this 2 pack of large Tank inserts that you can pair with the charcoal or bamboo inserts you already have. The secret to both war and childrearing is being well equipped, so this is the perfect option for cloth diaper veterans looking for a secret weapon.

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.

Great way to upgrade our older diapers to tanks and the baby grows. It’s amazing how much pee they hold!

Lena Mortley
Life Saver!

These inserts totally upped our diaper game. Zero leaks whatsoever. Super cute patterns, love the ease of installation in the diaper and they were the perfect addition to our rotation.

They're called tank inserts for a reason, eh? ;) Our tank inserts can hold 300ML of liquid and can stay on for 12hrs without change! The snaps and the label guide that comes with it will definitely put you at ease, Lena! Also, we mug any opportunity to rock a great print! ;) - Lil Helper Delight
