Stio Miter Stretch Lightweight Flannel Shirt

Review by Erin Trail

This vintage washed flannel from Stio gives all the vibes of your favorite flannels from the 90’s with some modern touches.

Detailed Review

The Stio Miter Stretch Lightweight Flannel Shirt is a light weight flannel that’s been updated a bit to bring this cozy favorite up to current performance standards.

The Stio Miter Stretch Lightweight Flannel Shirt is made from 97% Organic Cotton, 3% Spandex, with a fabric density 160g/m2. The shirt is slightly stretchy, but not as stretchy as a performance shirt like the Stio Shifter.

The vintage double wash give the Stio Miter Stretch Lightweight Flannel Shirt a just-right lived in feeling, straight from the store.

I am a women’s size medium according to the Stio size guide and I’ve found that the Stio Miter Stretch Lightweight Flannel Shirt is true to size. If you want to layer things underneath it, you may want to go up a size. But for wearing it buttoned up or layered with a t-shirt and unbuttoned, I found the medium to fit perfectly. The fit is slightly on the fitted, slender side. The bottom hem hits me just right, extending below the hips. The arm length and fit is exactly right on me.

I’ve been wearing the Stio Miter Stretch Lightweight Flannel Shirt regularly for nearly 2 months, mostly to casual outings and to the office. The shirt washes and wears beautifully. It gets machine washed on delicate and then air dried. I haven’t found that I need to iron the shirt or do much in the way of shaping it other than laying it flat to dry. The shirt hasn’t shown any signs of wear either (i.e. no pilling).

The Stio Miter Stretch Lightweight Flannel Shirt has some thoughtful styling, as is typical from Stio. The back has a subtle yoke, as a nod to Stio’s western roots. Yesterday, I noticed that the buttons have a tiny Stio logo imprinted on the edge, which I thought was a really fun little touch.

The colorways for this shirt are also really fun, giving a modern vibe without being a basic plaid.

Closing Thoughts

The Stio Miter Stretch Lightweight Flannel Shirt brings all of the fuzzy vibes to the Gen X uniform, while giving it some updated style touches. The flannel is available for both men and women, with men’s sizing ranging from S to XXL and women’s sizing ranging from XS to XL.

Erin Trail’s hobby is collecting hobbies. She’s a 5th Generation Coloradan and grew up exploring the outdoors on family camping trips and hikes. Her first backpacking trip was at eight years old to Grizzly Reservoir – she proudly carried all of her own gear those 3 miles from the main parking lot to the Reservoir.

Erin is an adult-onset athlete who started as a Masters Swimmer and then developed into a triathlete. She has completed 5 Ironman races and nearly 20 x 70.3 distance Ironman races, including the World Championship in Lahti, Finland, in 2023. In 2025, she raced for Team USA in Pontevedra, Spain for the World Triathlon Cross Tri World Championship. She placed 9th in her age group and was the 1st American woman in her age group.

Somewhere along her triathlon journey, she picked up deep love of cycling. Cycling encouraged her to see landscapes in a new way, learn new skills and to develop self reliance; now she often goes and does Type 2 rides just to see if she can do it. She’s got all the bikes: gravel, mountain, fat bike, time trial and road.

She is even known to combine her love of camping and cycling and go off on solo 24 hour overnight bikepacking trips in the mountains of Colorado. In addition to bikes, she teaches yoga, lifts weights, skis, SUPs and has recently purchased a campervan.

Erin is a former Montana park ranger with a degree in environmental engineering. She loves getting into technical details while putting her gear (and herself) through the paces. She shares her home in Colorado with her husband, Will, and her 3 cats (Zipper, Brewtus, and Simcoe).

Fall and winter 2025 will bring Erin to the “Adventure Side”, with many camping, vanlife, bikepacking, and mountain bike rides. Once the snow flies, she can be find resort skiing, fat biking, and triathlon training (inside and outside).

2026 will bring a National Championship Cross Tri race, a National Championship Road Sprint and Olympic Distance race, and hopefully a chance to represent Team USA once again in 2027 in Edmonton, Canada. She’ll also save lots of room for adventure time with her friends and husband.

When not adventuring, she can be found on a sunny patio somewhere, drinking beers with her husband.
