Sonic -20
$659.95 - $699.95
Description

　　This Backpacker Editors’ Choice award-winning big-mountain bag offers exceptional warmth and tuneability with a reduced environmental impact. The Sonic -20 features NEMO's next-generation Thermo Gill™ vents, with a new multistage zipper system that dramatically increases the usable temperature range of the bag and allows fine-tuning of comfort from within. Sonic’s chevron baffle construction better compartmentalizes down, eliminating migration and keeping the down evenly lofted. (Not to mention, it looks awesome.)

　　The shell and liner fabrics are 100% recycled fabrics and bluesign®-approved, and the premium 800 FP hydrophobic down is 100% Responsible Down Standard (RDS) certified. Years of history in the field yielded detailed upgrades on this bag, including a perfected profile, redesigned draft collar, and bolstered draft tubes. Its proven Toester™ footbox keeps feet warmer, provides a waterproof barrier against tent wall condensation, and protects down from moisture while drying damp clothes inside the footbox. Adaptable to whatever the mountain throws at it, Sonic continues to reverberate as the ultimate extreme weather companion.

Water Shoe Brand Dives Into Thru-Hiking: Astral Nosobo Hiking Shoe Review
　　When Grandma Gatewood became the first female to thru-hike the Appalachian Trail in 1955, she wore a simple pair of Keds sneakers to get the job done. At the time, her strategy to opt for a lightweight shoe was considered outlandish — or even comical. Everyone else who hiked long miles in the wilderness adopted a pair of heavy leather...

Is This the New Way to Climb Mount Everest?

Meet the Endurance Athletes Going the Extra Mile to Fight Cancer
　　When Scott Bauwens’s sister-in-law was first diagnosed with chronic lymphocytic leukemia a few years ago, he set a simple goal.

Mud Season Is Coming. Are You Ready to Survive It?
　　Whenever I encounter mud puddles on a trail, I flash back to one of the best-loved books of my 1990s childhood, We’re Going On A Bear Hunt. After contending with tall grass and a river, the characters in the book find themselves facing their latest obstacle, “thick, oozy mud.” “We can’t go over it, we can’t go under it,” they...

New Thru-Hike: ‘Northern Colorado Trail’ Opens for Debut Hiking Season
　　After Kevin Silvernale finished thru-hiking the Pacific Crest Trail (PCT) in 2016, he was hooked and started devising his own long-distance trail.

Even if buyers of boosted...

The Best Fishing Hats of 2025
　　What in the world is a fishing hat? That term seems like something a marketing team would create to target old men who are bored in retirement.
