"Experience next-level comfort on the trail with the AMPEX Bellin Insulated Self-Inflating Camp Pad. This hybrid design combines the plush comforts of a self-inflating foam bed with the packability of a camp pad providing you with a restorative night's sleep no matter where the hike takes you. The Bellin camp pad from AMPEX offers 4-season versatility with an R-value of 6.1. The 3""-thick open-cell foam provides full body support for a comfortable night's sleep. Innovative horizontal coring reduces bulk and weight of the foam while maintaining comfort and R-value. The 100% polyester stretch ripstop top provides a soft touch feel that conforms to the body for ultimate comfort without sacrificing durability on the trail. The 50-denier polyester bottom is built to withstand the demands of camping. The top and bottom have a thermoplastic polyurethane (TPU) coating for enhanced durability and waterproof protection from the ground. PVC-free recycled fabrics mean you can sleep sound knowing your purchase is safe for you and the environment. The included ripstop pump sack and a custom low-profile valve allows for fast inflate. The proprietary valve also includes a micro-adjustment feature that allows you to easily customize firmness for personalized comfort. When it's time to pack up, separate 1-way deflate valve prevents re-inflation making packing up a breeze. This self-inflating camping pad is designed to pair with AMPEX regular-size sleeping bags.
