The BellyFit Guarantee

We guarantee that the Universal Extender will fit your jacket.

If it doesn't, just reach out to us and we'll either find a solution or issue a full refund. 

The universal is designed to work with most jackets but there are a few exceptions. To avoid disappointment we suggest that all purchasers use the compatibility calculator below

For Classic Extender Purchases

Our Classic Extender uses a modular system that has adapters for some zippers but not all. Please use the compatibility calculator to see if the Classic Extenderwill work with your jacket.
