A little guidance. A better fit.
Start with their current weight, then check the waist and legs. Tap a size below to choose it.
| Size | Weight | 1 pack | 4 packs |
|---|---|---|---|
| ≤ 5 kg | 62 | 248 | |
| 4–8 kg | 56 | 224 | |
| Sold out | 6–10 kg | 44 | 176 |
| 9–13 kg | 40 | 160 |
| Size | Weight | 1 pack | 4 packs |

| ≥ 13 kg | 28 | 112 |
Counts are diapers. Weight ranges are a guide; every baby’s shape is different.
Between sizes?
Use the fit check. Gaps may mean the fit is too loose; a tight waist or deep marks may mean it is time to size up.

What's inside the 730
Every batch is lab tested before it reaches your door, not just the formula.
01 PFAS FOREVER CHEMICALS
Used in some water resistant coatings, PFAS do not break down in the body or environment. We test for 671 compounds per batch. Most premium brands test around 40, or do not share a number.
02 FORMAMIDE & PARABENS
Formamide comes from some foam and elastic manufacturing. Parabens are common synthetic preservatives. Both are screened for and have returned zero detections across tested batches.
03 HEAVY METALS
Lead, cadmium, arsenic and mercury are tested at trace level thresholds, well below regulatory limits, since heavy metals can build up in the body over repeated skin contact.
04 SKIN COMPATIBILITY
Beyond chemical screening, the finished diaper is patch tested under dermatological supervision. Excellent is the highest rating available, and the one Hoppi holds.
More Than a
Total Chlorine Free Claim
Most diapers use chlorine bleached wood pulp in the absorbent core. Even Elemental Chlorine Free can leave trace dioxins in fibers that sit against skin for hours.
Hoppi is pulp free by design, eliminating the need for pulp bleaching. Every material is verified Total Chlorine Free by an independent accredited lab, with the full report published for transparency.
Our purity standard
A lighter pant is only better if it is cleaner too.
