You strap your baby into the car seat with a well‑stuffed diaper, but by the time you arrive, their clothes are wet. This might be a compression leak, where pressure squeezes liquid out of the insert. Understanding why this happens helps you prevent it.
What Are Compression Leaks?
Compression leaks occur when the absorbent material is pressed, pushing liquid back out through the diaper’s waterproof layer. Microfiber inserts are particularly prone to this because they absorb quickly but release liquid under pressure. Long car rides, baby carriers and high‑chair straps compress the diaper, causing leaks.

Natural fibers like bamboo, hemp and cotton hold liquid more securely. They absorb slowly, so pairing a natural fiber insert under a microfiber layer keeps the diaper from flooding and reduces leaks. Consider replacing microfiber inserts altogether with multi‑layer hemp or bamboo inserts.
Proper Insert Placement
Make sure the insert lies flat and extends all the way to the front and back of the pocket diaper. If it bunches or twists, pressure is concentrated in one spot, increasing the risk of leaks. Use wider or contoured inserts to cover more surface area.
Additional Precautions
Avoid tight clothing over cloth diapers; compression from snug pants can cause leaks. When using car seats or carriers for extended periods, consider switching to a disposable diaper or a thicker fitted diaper with a wool cover. Check your diaper fit—gaps at the legs or waist can exacerbate pressure leaks.
FAQs Are compression leaks only caused by microfiber inserts? Microfiber is the most common culprit because it releases moisture when pressed. However, any insert can leak if absorbency is insufficient or compressed—natural fibers just hold on better.
Can I still use microfiber inserts? Yes, but pair them with a hemp or bamboo booster underneath to lock in moisture. Alternatively, switch to all‑hemp or all‑bamboo inserts for heavy wetters.
Do compression leaks happen in all diaper styles? They’re most common in pocket diapers with microfiber inserts. Fitted diapers or flats with covers distribute absorbency more evenly and are less prone to compression leaks.
