Eagle Series Ultralight Foam Pad

The Eagle Series represents Mountain Spring’s pursuit of extreme lightweight performance and exceptional warmth-to-weight efficiency in a minimalist foam sleeping pad system.

Constructed from NFPE (nitrogen-foamed polyethylene) foam, the pads combine advanced polymer engineering with precision molding to deliver reliable insulation at remarkably low weight. Each model is tested to the ASTM F3340-22 standard, providing efficient ground insulation for fast-and-light outdoor travel.

Available in four configurations: Eagle 99 / 199 / 299 / 399.
