The Woolx Stella Leggings are a thick and cozy option with a wide variety of uses.

I am a size medium + regular length on the Woolx size guide and I received a size medium/regular for testing. Compared to the Piper model, I found that the Stella leggings were less compressive and fit a bit looser. If you prefer a more compressive fit, size down.

The waistband, for me, is a true mid to high waistband, hitting me above the navel. The Stella model fits higher than the Piper model. Additionally, the legs of the Stella are longer than the Piper version, with a little extra fabric around the ankles. For reference, I’m 5’4″ and have freakishly long 31″ inseam legs and generally wear regular length inseam. I’m fine with the extra fabric around the ankles, but if you want a more streamlined fit at the ankles, consider sizing down to the petite length.

The design of the Woolx Stella Leggings combines traditional and updated features that enable these leggings range from being hidden as base layers to being part of an outfit. The waistband is more traditional, with a thick (but not too thick) elasticized band surrounded by soft Woolx merino wool fabric. There is a fun seam along the backside of each leg, almost reminiscent of pinstripes. All of the internal seams are flatlock, which means zero irritation as your move around. The interior texture of the leggings is the best feature – it’s almost like a low pile terry loop, which is incredibly comfortable and soft.

The Woolx Stella Leggings have held up very well over the past month+ of testing, with lots of wearing and multiple launderings. The fabric hasn’t pilled, pulled, or stretched, and still looks as good as the day it arrived.

As the weather finally turned colder in Denver, I’ve been reaching for the Woolx Stella Leggings often and I’ve found them to be really versatile AND comfortable. Due to the styling, the easily cross the line from functional base layers to athleisurewear to something you can wear out and about. These leggings can easily be worn under a dress or longer shirt, due to their opacity and styling.

Closing Thoughts

The Woolx Stella Leggings more traditional in style and design than their Piper Leggings sibling. The fit of the Stella Leggings is slightly more relaxed, so if you prefer a more compressive fit, consider sizing down. The Woolx Stella Leggings are available in seven colors and in women’s sizes ranging from XS to XL and in petite, regular, and tall lengths.

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.
