Wet Dry Bag - Mini Mathletes

Wet swimsuit in one pocket, dry change in the other, nothing soaking through your bag on the way home.

The Mini Mathletes wet/dry bag is a two-compartment bag with a waterproof divider — clean and dry on one side, wet and used on the other — sized for the swim bag, the diaper bag, and the daycare run.

What it does. The waterproof divider keeps a wet swimsuit or a soiled change away from clean clothes, snacks, and a phone. One bag instead of a plastic grocery sack and a separate pouch.

Material & safety. TPU-laminated polyester — waterproof and PVC-free, an upgrade on the PVC liners most wet bags use. Machine washable. Nickel-free hardware and a clip handle for a stroller bar. This is a parent-use bag, not a toy.

How to use it. Wet and used items in the lined compartment, clean and dry in the other. Clip the handle to a stroller or bag. Machine wash when it needs it.

Who it's for. Parents, from about 6 months on — swim days, blowouts, daycare, travel. Useful well past the baby years.

The design. Mini Mathletes carries numbers and small doodles on white, so the practical thing also looks like something you'd choose.

Care. Machine wash and hang dry. The TPU liner wipes clean between washes.

Where it goes. Swim lessons, the beach, the daycare cubby, the diaper bag on a blowout day. Wet or soiled on the lined side, clean and dry on the other, and a clip handle so it rides a stroller bar instead of taking up an arm. TPU vs. PVC Most wet bags line with PVC. This one uses TPU — waterproof without the PVC, and it holds up in the wash instead of cracking. A small material choice that decides whether the bag lasts a season or a few years.

Designed in Canada. Loulou Lollipop launched in Vancouver in 2014 with one swaddle and one teether. Everything since has been tested on the founders' own kids before it went to production.
