Description

Our 9” Ridge Long Boxer Briefs use the same super soft Merino wool and design as our bestselling original boxer brief. Our Long Boxer Briefs are made to accompany you wherever the day takes you. These briefs are made with our (m)Force™ Technology, a nylon core-spun Merino wool that improves strength and reduces abrasion, plus a hint of spandex to provide long-lasting stretch and recovery.

They have a gusseted crotch, an easy-to-use fly and flatlock seams to minimize rubbing. They have all the benefits we love in Merino wool: odor resistance, quick drying, temperature regulating and moisture wicking. Our underwear are sustainably made and free of chemicals and microplastics, so you’re doing the right thing for your skin and for the planet when you wear them.

Product Features
  • Merino wool blend that’s odor-resistant, breathable and temperature regulating
  • Longer length to resist riding up during use and provide more coverage in cool weather
  • Easy fly
  • Gusseted crotch
  • Flatlock seams
  • Branded waistband
  • Printed label and removable care label for max comfort
Fabric Details
  • 83% Merino wool, 12% recycled nylon, 5% spandex
  • 170 GSM fabric weight
  • 17.5M Merino wool
  • Free of harmful chemicals

Care: Machine wash on warm or cold, hang dry, do not bleach or dry clean, iron on low wool setting. Learn more.

Sizing/Fit

Danila (in Old Growth) is 5'10" wearing a Large.
