Sonic is designed to be the only bag you need from -20°F to 40°F.
The award-winning high mountain bag from Backpacker Editors' Choice that delivers exceptional warmth and adaptability with a reduced environmental impact.
This bag features next-generation Thermo Gill™ technology, with a new multi-level zipper system that significantly increases the usable temperature range of the bag and allows comfort to be adjusted from the inside.
Sonic's chevron construction better compartmentalizes the down, eliminating migration and keeping the down evenly lofted.
The shell and lining fabrics are 100% recycled and bluesign®-approved materials, and the premium 800 FP hydrophobic down is 100% Responsible Down Standard (RDS) certified.
Years of field history have led to detailed improvements to this bag, including a refined profile, a redesigned draft collar, and reinforced draft tubes.
The proven Toester™ footbox keeps feet warm, provides a waterproof barrier against condensation on tent walls, and protects the down from moisture while drying wet clothes inside the footbox.
Adaptable to whatever the mountain throws at it, Sonic is the ultimate companion for extreme weather conditions.
