Aerogel Insulation Enables Extremely Compact, Lightweight Sleeping System

Improves thermal performance while reducing pack size

CHALLENGES

Develop a new sleeping system for the Marine Corps that improved thermal performance while reducing pack size.
Provide acceptable level of comfort, heat retention, and internal humidity in an operating range of 27° to - 40°C (80° to - 40°F).
Ensure the system would need minimal reconfiguration or user adjustment in the field.
The system needed to be water-resistant for use on moist ground or shallow standing water (less than ¼ in).
It could not use an internal or external power supply or rely on chemical reactions that must be replaced or reset.

AEROGEL SOLUTION

Aspen Aerogels and Slumberjack designed a new sleeping system with Spaceloft® 3251 and Spaceloft® 6251 placed to capitalize on the high thermal value and compression resistance of aerogel.
This strategic placement of aerogel insulation reduced the pack size while maintaining the Clo value.

BENEFITS

Spaceloft displayed Clo values over 11 per inch thickness, superior flexibility and no water absorption.
Spaceloft outperformed lofted insulations, which lose thermal resistance when compressed by the weight of a person. Spaceloft maintains its ithermal performance even when compressed.
