# Alternity Apparel > Adaptive, sustainable clothing by Zip Us In. Home of the safety-certified Cariagan® maternity-to-babywearing cardigan and the final Zip Us In heritage jacket-expander collection. Alternity is the rebrand of Zip Us In, the UK adaptive-clothing label founded by Kate Bell — featured on BBC's Dragons' Den (2020), ITV, and recognised by Barclays Entrepreneur of the Year. The brand designs garments that adapt through pregnancy, postpartum and babywearing, so parents buy fewer clothes and keep them for longer. Flagship product: the **Cariagan®** — the world's only cardigan independently certified for newborn carrying (PD CEN/TR 16512:2015). Worn as a wrap cardigan in pregnancy, it converts into an ergonomic newborn carrier (3.5–9 kg) with no separate sling required. Heritage: the original **Jacket Expander Panel** (as seen on Dragons' Den) zips into most coats to extend them across a bump in pregnancy, then converts into a babywearing panel. Final Zip Us In stock — once gone, permanently discontinued. Based in the United Kingdom. Ships UK (£3.99) and internationally (£8.99), tracked, up to 5 items. 30-day returns on unworn items; heritage items are final sale. ## Pages - [Home](/): Brand introduction, range overview, Cariagan® feature, heritage collection band. - [Shop](/shop): Full product catalogue across Alternity and Zip Us In Heritage. - [Our Story](/our-story): How and why Alternity was built after Zip Us In. - [About Kate](/about): Founder Kate Bell — Dragons' Den, ITV, Barclays Entrepreneur of the Year. - [The Journal](/blog): Articles on adaptive clothing, motherhood, babywearing and sustainable living. - [Contact](/contact): Customer, press and partnership enquiries. ## Products - [Cariagan® maternity-to-babywearing cardigan](/shop/cariagan): Safety-certified newborn carrier cardigan (PD CEN/TR 16512:2015).
