These replacement sleeves are specifically designed to fit our 2024 collection and onwards. In 2024, we updated our zipper hardware to a smoother, more durable design. To check if your garment is compatible, look at the zipper on the shoulder. If it has the word “Ideal” on the back, these spare sleeves will fit perfectly.
No. These sleeves are replacement parts only and can only be attached to products that already feature zip-off shoulders (the Transition Bag or Transition Suit). Standard Swaddle Up™ garments do not have the necessary zippers to attach these sleeves.
Most parents find that having 2 x replacement sets (for a total of two pairs) is the "sweet spot". This allows you to have one pair on the garment, one in the wash, and a backup for those middle-of-the-night emergencies. This keeps your baby’s sleep environment fresh and dry without needing to wash the entire suit daily.
Yes. For safety and a secure fit, you must match the sleeve size to the size of your Transition Bag or Suit. For example, if you have a Large Transition Suit, you must select Large Spare Sleeves. Zipper lengths are precisely measured for each size (M, L, and XL) to ensure the correct ergonomic fit for your baby's development.
Yes! These spare sleeves are cross-compatible with both the Swaddle Up™ Transition Bag and the Transition Suit, provided both items are from the 2024 "Ideal" zipper collection. This makes it easy to swap between your favorite transition styles.
