Keep your flannel looking great with these simple washing and drying steps. Learn how to care for your Mountain Shirt and extend its life.
Quick answer
Wash your Mountain Shirt inside out in cold water on a gentle cycle, then tumble dry low or line dry to prevent shrinkage and fading.
Why flannel needs special care
The Mountain Shirt is made from 100% organic cotton midweight twill flannel. Flannel's brushed surface gives it that soft feel, but it also means the fibers are more prone to pilling and wear if handled roughly. A little care goes a long way to keep that cozy texture.
What about the Utility Shirt?
The Utility Shirt Chambray is a lighter 100% organic cotton chambray that can follow the same washing routine. Because chambray is a plain weave, it's less prone to pilling than flannel, but cold water and gentle drying still protect the fit and color.
How to care for your Mountain Shirt
- Turn it inside out: Before washing, turn the shirt inside out. This protects the outer surface from abrasion and helps prevent fading. Don't skip this step—it's the easiest way to reduce pilling.
- Wash in cold water on gentle cycle: Use cold water and a gentle cycle with a mild detergent. Avoid bleach or fabric softener, which can break down cotton fibers and dull the color. Hot water can shrink flannel and fade the plaid pattern.
- Tumble dry low or line dry: Dry on low heat or hang to dry. High heat can shrink the shirt and damage the brushed finish. If you use a dryer, remove the shirt while it's still slightly damp to reduce wrinkles. Overdrying is the most common cause of shrinkage in flannel.
- Iron on medium if needed: If the shirt comes out wrinkled, iron it on a medium setting while it's still slightly damp. Use steam for stubborn creases, but avoid ironing directly over the plaid pattern's edges to prevent scorch marks. A steamer is gentler on the brushed surface than an iron.
- Store it folded or hung: Fold the shirt or hang it on a padded hanger to maintain its shape. Avoid wire hangers, which can stretch the shoulders over time. For long-term storage, fold it to prevent dust from settling on the shoulders.
