Out of everything Eco Pea Co. sells, one product carries the vast majority of the brand’s review history: the Bamboo Diapers box, at $99 (or $89 on subscription), sitting at 4.7 out of 5 stars across 1,195 reviews. I went through a wide sample of that feedback, plus the ingredient sheet and size chart, to see if the reputation holds up.
What it’s made of
The top sheet is bamboo viscose, chosen for being softer against skin than the plastic-based top sheets on most mainstream diapers. The absorbent core combines organic, EcoCert-certified bamboo pulp with a super absorbent polymer layer, plus a thin aloe-infused strip meant to soothe irritated skin.
Eco Pea Co. states the diapers are free of chlorine, parabens, phthalates, formaldehyde, and added fragrance. The packaging itself is 100% compostable, and the brand uses water-based ink for printing.
Sizing and fit
Sizes run from Newborn (under 10 lbs) through Size 6 (35+ lbs), with pack counts ranging from 190 diapers in a Newborn box down to 108 in Size 6. Full chart:
| Size | Weight range | Diapers per box |
| Newborn | Under 10 lbs | 190 |
| 1 | 8-14 lbs | 180 |
| 2 | 12-18 lbs | 168 |
| 3 | 16-28 lbs | 144 |
| 4 | 22-37 lbs | 132 |
| 5 | 27+ lbs | 120 |
| 6 | 35+ lbs | 108 |
This is the part where reviews get less uniform. Several parents reported the diapers running smaller than the chart suggests, with tight leg openings even on babies who fit comfortably in the listed weight range. If your baby is at the upper end of a size bracket, sizing up is the safer call.
What buyers are actually saying
The positive reviews cluster around the same three points: softness, absorbency, and reduced rash. “They’re almost like cloth diapers, so soft,” one reviewer named Shannon wrote, adding that they also held up against leaks. Another parent, Olha, said Eco Pea Co. was “the only brand that didn’t cause rashes or allergic reactions” for her child.
The critical reviews center on fit and durability. One three-star review specifically flagged “lots of blowouts and irritating on the belly, back and thighs.” Separately, some reviewers on independent sites described the tab straps losing their grip against the diaper’s textured outer layer, and a few compared the outer texture to cardboard next to plusher brands.
How it compares
Against Eco Pea Co.’s own newer Cotton Enhanced line, the Bamboo Diapers have the far longer review track record (1,195 reviews versus a handful for the new line), so they’re the safer first purchase if you’re testing the brand. Against outside competitors, the closest match is Kudos, which uses a cotton top sheet instead of bamboo and tends to fit larger.
Should you buy it
If your priority is a documented, fragrance-free ingredient list and a diaper with real rash-prevention feedback behind it, the Bamboo Diapers box backs that up with volume, not just marketing copy. Order true to weight or size up if your baby sits near the top of a bracket, and expect a firmer, less plush outer texture than premium mainstream brands.
