Smartwool Women's Active Fleece Wind 1/2 Zip Review

I'm truly impressed by Smartwool's Active Fleece Wind 1/2 Zip! If you're a runner or cyclist, you know just how miserable wind can make the activities we love so much. This outer layer has become one of my go-tos since late fall. As much as I love a pair of thumb holes, that's not the only feature that gives this fleece a 10/10 in my book.

Before digging into the details, here are some specs to know: 

  • Made in Vietnam
  • Main Body: 47% Polyester, 38% Merino Wool, 15% Elastane
  • Overlay: 85% Nylon, 15% Elastane
  • Pockets: 100% Polyester

If you've never owned wool clothing, it's important to care for the items properly to ensure longevity. Smartwool suggests the following:

Care

  • Machine Wash Cold Gentle Cycle
  • Wash With Like Colors
  • Do Not Bleach
  • Dry Flat
  • Cool Iron As Needed
  • Do Not Iron Decoration
  • Do Not Dry Clean

Features

Merino wool lined with synthetic fabrics facing outward. Internal panel prevents wind from coming through the zipper.
Reflective elements are rather small, but can be found on the thumbholes, lower rear panel, and next to chest pocket.
Soft fabric panel protects neck from zipper irritation when fully zipped

Performance

As a runner and cyclist, I'm always looking for ways to make outdoor winter training a bit more enjoyable. The Smartwool Women's Active Fleece Wind 1/2 Zip is quickly working its way into my regular rotation. The soft, stretchy fabric is lightweight enough to feel athletic, yet it still performs like a wool product; it wicks, insulates, and doesn't hold onto nasty odors. The wind-proof panel is a serious bonus. With the zipper fully reinforced by a soft fabric panel, no gusts are getting through! 

Although I didn't love the boxy fit at first, I've come to realize that it accommodates layers underneath--an essential feature for outdoor cycling or skiing specifically.   

Since this Fleece Wind 1/2 Zip retails for $170, consider it an investment in your winter athletics. If taken care of properly, this layer will go the distance. I've already put mine through several wash/dry cycles and it shows no signs of wear. 

This is an incentivized review

Smartwool provided me with this 1/2 zip in exchange for my honest review.
