Feature: 1. Durable Material: The outdoor inflatable cushion is crafted with high density 30D nylon TPU material on the surface for softness, abrasion, and tear resistance. Meanwhile, the internal layer features a TPU film for superior airtightness, water resistance and dampproof. 2.

Once deflated, it can be effortlessly packed into a backpack without consuming much space. 5.
