Sea to Summit's sleeping bags use responsibly sourced 750+ LOFT ULTRA-DRY DOWN, which re-expands to over 750 cubic inches after compression and requires less down to achieve the same temperature rating, with independent testing by IDFL and RDS certification.
Sea to Summit is certified by the Responsible Down Standard (RDS) for using 100% RDS certified down in their sleeping bags and quilts, ensuring animal welfare practices are upheld throughout the supply chain.
Bags with zip coupling symbol can pair together for cozy adventures.
The Free-Flow triple-zip design balances warmth and ventilation, with arm movement freedom and mini-quilt option.
