Awesome shirt but fit is large

  • Fit:Runs large
  • Height: 6'0"
    Weight: 180 lbs
    Size Purchased: Large

Definitely agree with some of the reviews here on fit. As with all my other Prana shirts I went with the Large, but needed to exchange for a Medium. I go 6' and 180.


Almost perfect, but had to return

  • Familiarity:I gave it as a gift but have feedback to share
  • Fit:Runs small

Bought for husband to replace another waffle lined flannel he has loved to death. We wanted to love these shirts so much and just couldn't. They may be baggy on most buyers, but on his 6'3" 220lb frame they were just too tight across the chest and back. The arms were almost the right length, but were also an annoying half inch too short for him. The fabric is nice, colors are gorgeous and the lining seems amazing for an extremely versatile piece, just not for him. I'm sad to return them, and hopeful we'll find the right one next time.


Replaced my Hoody

  • Familiarity:I've used it several times
  • Fit:Runs large

Very soft flannel, and comfortable. Pretty functional for a lot of things: Bike work, camping, hiking, fishing...I use it for everything. It replaced the hoodies in my wardrobe.

FIT: 6'2" 165lbs, Size L has a lot of excess fabric. Went with size M without losing much sleeve length (I'm a 35in sleeve and the size M cuff fit perfectly to my wrist). Back length was about the same for sizes M and L. My only complaint is that I wish the back length was a little longer; even 1/2 to 1 inch longer would be dope.


Awesome shirt.

Great fit, and style. Really warm flannel with the thermal knit inside. Quality. I'm usually a medium (avg build - 5'8'') but a small in this. Would definitely buy again, love this shirt.
