Learn how to fit, wash, and care for Ecoposh OBV Training Pants so the organic bamboo velour stays soft and the hidden waterproof layer keeps working.

Quick answer

Choose the size that matches your child’s current waist and rise, pull them on like underwear, and wash them with a normal cloth diaper routine that avoids bleach and fabric softener. That keeps the organic bamboo velour soft and the hidden waterproof layer intact.

Why OBV behaves differently from cotton training pants

Ecoposh OBV Training Pants use organic bamboo velour on the outside and a hidden waterproof layer inside. That combination gives you the soft, stretchy feel of bamboo with a dry barrier, which is different from plain cotton training pants that absorb but stay wet against the skin. The trade-off is that the waterproof layer needs gentler care than an all-cotton trainer, and the velour can pill if you wash it with rough items like hook-and-loop tabs or zippers.

Fit checkpoints that prevent leaks

The pants come in three sizes, so start with the size that matches your child’s current measurements rather than buying ahead. A good fit sits snug at the waist and around the legs without leaving red marks, and the rise should cover the bottom fully when your child squats. If the waist gapes or the leg openings lift away during movement, size down or try a different size before assuming the absorbency is too low.

How to fit, wash, and care for Ecoposh OBV Training Pants

Measure before you choose a size: Check your child’s waist and rise against the size options, then pick the closest match. Common mistake: sizing up for growth room, which causes gaps at the legs and leaks. A snug fit at the waist and legs matters more than room to grow.
Do a short wear test: Put the pants on and watch for 10–15 minutes of walking, squatting, and sitting. Check for red marks or gaps at the leg openings. Common mistake: judging fit only while the child stands still. If you see gaps during movement, try a different size before washing.
Pre-rinse before the main wash: Rinse the pants in cool water to remove urine or solids before adding them to your regular cloth diaper load. Common mistake: skipping the pre-rinse and washing in hot water first, which can set stains and odors. A cool pre-rinse makes the main wash more effective.
Wash with a cloth-safe detergent: Use a detergent without bleach, fabric softener, or optical brighteners. Wash on a normal cycle with like items, and avoid hook-and-loop tabs or zippers that can pill the velour. Common mistake: adding fabric softener, which coats the waterproof layer and reduces absorbency. Fabric softener is the most common cause of reduced absorbency in OBV trainers.
Tumble dry low or line dry: Dry on low heat or hang to dry. High heat can damage the hidden waterproof layer over time. Common mistake: drying on high heat to speed things up, which shortens the life of the waterproof barrier. When in doubt, air dry the pants to protect the waterproof layer.
