Merries Pants L 54 pcs (Japan JUMBO Edition, New Upgraded 14-Hour Super Absorbency) 🌟As low as $110/pack

Once your baby reaches the Size L stage, their activity levels are truly "off the charts"—running, jumping, and climbing all day long. Plus, their disposable diaper output increases significantly at night or while out and about. If standard pull-up pants are too bulky, they not only hinder your baby’s movement but are also prone to side or back leaks the moment they sit or roll. Highly recommended by Japanese moms, the Merries Premium Training Pants (Size L) have undergone a brand-new, cross-generational scientific upgrade! Directly imported from Japan, this JUMBO 54-count value pack is centered on "Skin-Research Born" technology. Featuring a revolutionary "14-hour absorbent core" and a "10% slimmer design," it provides ultimate leak protection while offering your baby an airy, unrestricted, and dry experience. Give your active baby 24 hours of non-stop, premium gentle care!

Newly upgraded "14-hour★ long-lasting ultra-absorbency"! 10% slimmer yet firmly locks in massive amounts of urine:

• 14-hour worry-free ultra-absorption: Designed for the surging urine output of older babies, the new version significantly upgrades the core absorption specifications, providing up to 14 hours of ultimate leak-proof dryness (oshikko lock). From bedtime at night until waking up in the morning, it stays secure, absorbing and locking in fluid all night long without seepage.
• 10% slimmer design (10% slim): Compared to the previous version, the new absorbent core is boldly reduced in thickness by 10%! Say goodbye to bulky "big-bottom" shapes. The material is more supple (shinayaka) and form-fitting, perfectly following your baby's hip contours for greater flexibility.
• Exclusive "Leg-Cuff Synchronized Absorption" triple protection: The absorbent area has been fully widened, extending absorbency even to the edges of the leg cuffs! Combined with "perfect fit" elastic ruffles, no matter how much your baby strides or rolls, it seals all gaps to achieve true "0 leakage."

5 billion micro-pores + comfortable waist air tunnels to let heat and moisture escape in a "woosh":

• 5 billion breathable micro-pores: Verified by electron microscopy, the surface of each training pant features over 5 billion ultra-fine exhaust pores. Together with a fully breathable layer, it releases moisture at the speed of light to prevent diaper rash.
• Pioneering "Waist Air Tunnels": Specially designed air circulation channels at the baby's tummy and waist—where they sweat the most—allow humid air and sweat to "woosh" (suru~) out, keeping the entire waistband non-sticky and breathable.
• 2.5x super-stretch waist (2.5x nobīru): The waistband stretches easily up to 2.5 times its original size, making it effortless to put on active babies. Featuring "soft-fit" black technology, it achieves the golden balance of "staying on without sliding down, while being gentle without leaving marks." It is also a winner of the Japanese GOOD DESIGN Award!
