What You're Really Comparing
Esembly's two-part cloth diaper system uses an absorbent Inner (fitted diaper) and a waterproof Outer (diaper cover). The Inner + Outer Bundle gives you 3 Inners and 1 Outer—a starter set for one baby. The Full Bundle, by contrast, is a larger kit designed for full-time cloth diapering. The key difference is scale: the Full Bundle includes multiple Inner + Outer Bundles plus extras like a Wet Bag and Washing Powder. This guide focuses on the Inner + Outer Bundle vs. the Full Bundle so you can match the kit to your diapering style.
Inner + Outer Bundle vs. Full Bundle: At a Glance
Both bundles use the same two-part system: an absorbent Inner and a waterproof Outer. The choice comes down to how many diapers you need and whether you want the extra accessories.
- Inner + Outer Bundle (Snap or Tie): Contains 3 Inner diapers and 1 Outer cover. Ideal for part-time diapering, as a trial, or for building your stash gradually. You'll need multiple bundles for full-time use. The bundle is available in Size 1 (7-17 lbs) or Size 2 (18-35 lbs) and with a choice of Outer color/print.
- Full Bundle: A larger all-in-one kit that typically includes multiple Inner + Outer Bundles, a Wet Bag, and Washing Powder. Designed for full-time cloth diapering from birth to potty training. It gives you enough diapers to wash every 2-3 days without running out.
How Many Diapers Do You Really Need?
The answer depends on your baby's age and whether you cloth diaper full-time or part-time. Esembly recommends 24 Inner diapers and 6 Outer covers for full-time cloth diapering. That works out to 8 Inner + Outer Bundles. If you're starting with a newborn, you may need 24-30 Inners and 6-8 Outers. For part-time use, a single Inner + Outer Bundle might be enough to get started. The Full Bundle is built to meet the full-time recommendation right out of the box.
Inner + Outer Bundle Product Details
- Inner + Outer Bundle (Snap): 3 organic cotton Inner Snaps diapers and 1 waterproof Outer diaper cover/swim diaper in a color or print of your choosing. This gives you the core two-part system: the absorbent Inner and the waterproof Outer. You get enough Inners to rotate while Outers are reused.
Inner + Outer Bundle (Snap) - Inner + Outer Bundle (Tie): 3 organic cotton Inner Ties diapers and 1 waterproof Outer diaper cover/swim diaper in a color or print of your choosing. The Inner Tie uses soft fabric ties for a plastic-free closure. It's made of organic French Terry cotton that dries quickly. Both bundle types include the same Outer cover.

When to Choose the Inner + Outer Bundle
The Inner + Outer Bundle is a smart choice if you're new to cloth diapering and want to try the system without a big commitment. It's also ideal for part-time diapering (e.g., weekends or evenings) or for building your stash gradually. Because you can reuse the Outer cover multiple times before washing, one bundle gives you several changes before laundry day. If you have a baby in one size range, you can buy the bundle for that size and add more later. The bundle is available with either Inner Snaps (snap closure, structured cotton twill) or Inner Ties (tie closure, stretchy French Terry). Both offer the same absorbency.
When the Full Bundle Makes More Sense
If you plan to cloth diaper full-time from birth, the Full Bundle saves you the hassle of calculating how many bundles to buy. It provides enough diapers to wash every 2-3 days, plus the Wet Bag for storing soiled diapers and Washing Powder to get them clean. The Full Bundle is also a good value if you're starting from scratch, because buying individual Inner + Outer Bundles to reach the full-time count would cost more overall. For part-time or trial use, the Full Bundle may be more than you need.
Key Considerations for Your Decision
Both bundles use the same Outer covers, which are made of 100% GRS certified upcycled polyester TPU and can double as reusable swim diapers. The Inners are made of organic cotton (twill for Snaps, French Terry for Ties) and are OEKO-TEX Standard 100 certified, free of lead, BPA, PVC, and phthalates. The Outer covers have two rows of snaps at the waist to adjust fit independently from the legs. If you're unsure how many you need, Esembly offers a quiz to help determine the right quantity for your situation.
