Description

We knew the second we slid the Sierra Shirt on that this wasn't going to be one of those flannels that just sat idly by in your closet... No, this is not that type of shirt. This is one of those pieces that makes you question what you did before. Made from a 7oz twisted cotton, and outfitted with our custom plaid flannel design, this is a piece that actually feels as good as it looks. 

THE SPECS + DETAILS

  • 7oz 100% cotton yarn dyed twisted flannel
  • Custom INR metal buttons
  • Double chest pockets with top entry flap
  • Locker loop draw cord on inside collar
  • Imported
Wash & Care

Caring for Hand-Knit Cotton:

Cotton is more forgiving than wool but still benefits from gentle handling, especially in hand-knit form where the stitch structure is more open and delicate.

  • Hand wash in cool water with a mild detergent, or use a machine’s delicate/hand-wash cycle in a mesh laundry bag.
  • Cotton can handle slightly warmer water than wool, but keep it under 40°C to preserve color and shape.
  • Lay flat to dry just as you would with wool. Cotton knits can stretch when hung wet.
  • A cool iron on the reverse side can refresh the fabric if needed — avoid ironing directly on textured stitches.

Reviews

This is a very nice

"This is a very nice shirt, made with heavy soft fabric. The fit is a little large, but will be good for layering. It seems to be excellent quality. I am very happy with this purchase."

— Warren F. (5/5)

Rock'n Flannel

"Very high quality flannel. Nice and thick to keep you warm on those cool fall nights. I like the parachute cord hanger, nice touch. I found that the shirts and jackets run a bit small on me so I always size up one or two from my usual size. That said, I don't like flannels to fit too tight because I usually layer with a t-shirt or Henley underneath for added warmth."

— Craig L. (5/5)

Superb quality shirt and it's an instant favorite

"Beautiful shirt with a great cut and fit. Flannel is thick but not uncomfortably thick. Metal buttons are a nice touch. Perfect shirt for PNW fall and winter, or even cool summer nights."

— Mick S. (5/5)

"Perfect mid layer flannel it feels heavier than it is. It fits perfect though and the colors are awesome. Everyone at work was surprised by the opacity got a lit of compliments."

— Jason B. (5/5)

Amazing quality shirt. The heaviest

"Amazing quality shirt. The heaviest flannel I’ve ever owned- it feels like my grandpa’s from back in the day. It’s fits a little short and I’d be scared to dry it but the fabric is amazing"

— David M. (5/5)
