Making Gear for People with Boobs with Symbiosis Gear Founder Sarah Berkeley

In today's episode of Backpacker Radio, presented by The Trek and brought to you by Topo Athletic, we are joined by Sarah "Mellow" Berkeley, founder of Symbiosis Gear, a pack-making company designed specifically for people with boobs. Sarah shares insights into her unique upbringing in a small log cabin in rural Colorado, her adventures on the Long Trail, PCT, Colorado Trail, and half of the CDT, and her journey to creating a backpack tailored for primarily women. We dive into the inspiration behind her patented S-shaped shoulder strap, the challenges of starting a business with no prior industry experience, the help she's received from fellow members of the cottage industry, her plans for future expansion, and much more.

We wrap the show with the announcement of the 2025 Badger Sponsorship, news of a hiker found dead near Mt. Whitney, a debate on when poop officially starts to smell like poop, and the Triple Crown of middle-aged happiness.
