About this model

Got a Therm-a-Rest mattress, and want to use the Exped Ultra Pump? The included adapters will not work. This adapter fits both! The default adapter for the Exped mattress fits perfectly in this adapter. Attach the adapter with a cord to the pump, and never lose any of these adapters. Print in TPU. Might work with PETG, but not tested. Happy hiking/traveling!
