Our recommendations

Oaki Trail Rain Pants
Size 4/5 has a 19.5-to-25-inch waist range and a 17-inch inseam. In size 6/7, the inseam jumps to 19 inches. Sizing up buys two more inches in the leg, as well as extra room at the waist.

Jan & Jul Kids Single Layer Rain Pants
The unlined version makes sense as a spare pair for a school bag. Jan & Jul says it rolls up small, and allows cold gentle machine washing after use.

Reima Lammikko Rain Pants
This is a bib for the child who still has an adult helping with dressing. The front and back come up above the waist, and detachable foot loops hold the legs over boots. At a school that expects children to handle bathroom trips alone, suspenders need more thought.

Columbia Cypress Brook II Pants
The size chart starts at XXS (4/5) and runs to XL (18), which puts this one on the older-child list.

How I narrowed it down
I can’t identify the pair our boys wore, so I used maker pages to compare the four named pairs below.
- Jan & Jul sells a separate fleece-lined version; this guide uses its single-layer pants. The Columbia details apply to Cypress Brook II, style 1544101.
- The linked Reima parent discussion is about the brand’s outerwear in general, not a test of this exact bib.
- The product scenes use manufacturer reference images with generated rooms, surfaces and signs of mud. They are illustrations, not photos of our family’s gear.
I'm Matt, a dad of two boys. If we've used something at home, the card says personally tested. The rest I read up on. I keep a weekly list of kids' product recalls. How I pick.
