Love my Sleeves in a bag.

I got my black Sleeves and am enjoying them in creating an extra layers to my arms. I put them on over my bra or cami then add a top with 3/4 length sleeves and now I have the extra warmth and the length of the SLEEVES IN A BAG plus it adds an artsy flair. I have gotten questions and compliments about the added layer with no bulk of an extra layer but still adds warmth.

I love this product. I should have ordered one size larger but only because I didn't realize the fabric would fit more snug. The size was fine, I just wanted a looser fit. I will wear the smaller size and have ordered the next size up as well.

FAQ

What Makes the Fabric Sustainable?

So about this
“Modal” you keep hearing about...

“It’s sustainable + yada yada yada = clothes.”

So what happens in the “yada yada yada” phase?

A lot, actually.

When we refer to modal as a sustainable
Fabric, we’re implying it is something that can hang-in for the long-haul. An ideal that even cotton is at risk of not being able to claim for much longer.

But modal comes, in part, from the beechwood tree. The really magical thing about this is, beechwood trees multiply by the process of “rejuvenation”. They propagate by themselves! There isn’t an extra amount of
Planting or irrigating necessary to sustain the beechwood tree. They just take nature into their own hands as if to say “We are here to help, guys! Stand back - We’ve got this.”

And it’s not like Beechwood fibers are inferior. In fact, they are SOFT, they are cozy, they are strong, and they are meant to last - which helps to solve the most important need of all - reducing the amount of things discarded and replaced.

So when you shop with Steel Pony, and invest in our statement pieces, you can be confident that your investment holds enormous, long-lasting value that will pay for itself in terms of long-lasting quality and durability.

Slow fashion, and investment in the bigger picture, is what our style is all about. When you walk through life in our gear, and someone inevitably mentions that they love your outfit, you’re given the gift of an opportunity to explain why what we wear, what we stand for, and what it means for our future, MATTERS. And THAT is how we can each make a difference, one day, and one casual conversation, at a time.

What about the Sizing?

Figuring out size is more about arm width so the measurements below give you the actual measurement of the garment at the upper arm and your bra number measurement .Consider how you would like them to fit.  If your upper arm measures bigger then the measurement the fit will be more fitted.  If it is smaller it will be more roomy.  Also remember this fabric has a lot of stretch
