YMMV Review

For those who have not read any of my reviews yet, I like wool. There are 4 main attributes to wool; odor-free, temperature regulation, breathability, and renewable. For this reason I was excited to try a cycling jersey made out of wool, well mostly wool. These were reviewed in conjunction with the Smartwool Flagstaff Bib Shorts.  If you would like to learn more about wool, check out the article linked below.

Design ★★★★☆

The Smartwool Flagstaff Jersey is a slim fitting jersey. It is made out of 75% wool and 25% polyester to give it the benefits of wool and to retain shape. The jersey is made out of 170 g/m2 fabric which is on the light weight side of the wool scale. 150 g/m2 is the lightest weight wool fabrics so this is rather close. The jersey is made out of two types of fabric. The main fabric is a standard knit and there is a mesh fabric used under the arms, along the top of the back, and the pockets. The mesh fabric allows the jersey to breathe a little better in those locations. This is a smart choice for the pockets as there are not two layers of the thicker fabric on the back when the pockets are not in use. This will keep your lower back slightly cooler. The mesh material also stretches more than the main material and creates a better fit. The jersey is made with mostly flatlock seams to reduce chafing. Only the arms are not flatlock seams. There is also a full zip front to accommodate venting. The jersey has reflective logos and piping for low light visibility. The back has 3 pockets and inside the center pocket there is a concealed zipper pocket with audio port. The bottom hem of the jersey has a elastic gripper to keep your jersey from riding up. At the top of the zipper there is a little zipper garage to protect the riders neck. The neck does sit a little lower than other jerseys I have and the collar is also lower than other jerseys. The arms have a little elastic at the cuffs but this is not as tight as some elastic cuffs of other jerseys.

Audio Port

Fit ★★★★☆

I have used this jersey on rides as short as 15 miles and as long as 90 miles. It has been comfortable on all distances with no issues of chafing or major fit issues. The jersey is in fact a trim fitting jersey. From the mid section up the jersey fits me really well. In the chest, shoulders, neck and arms the jersey it tight but not compressive. The bottom hem of the jersey is a little tight on me. That may be more me than the jersey though. =) The pockets are a good shape and fit what I need to carry. The mesh pockets work well and breathe a bit more than the standard fabric does. This keeps my lower back slightly cooler when the pockets are not in use. The Flagstaff Jersey is a good length in the back, not short but not long either. It interfaces really well with the Flagstaff Bib Shorts. The fabric is also soft to the touch and has not been itchy at all.

Performance ★★★★☆

The Flagstaff Jersey has performed well. It is not quite as cool on hot days as some of my other jerseys are but I have liked using it on all but the warmest days. It does a good job of moving moisture off the skin but it does take slightly longer to dry than a synthetic jersey.  This is really close though. I really like how I can wear this jersey more than once if needed and it does not stink. This is great for taking on trips when I do not have room for multiple kits. The sizes of the pockets are good and have not noticed the jersey sagging with weight in the pockets. The polyester mix does a good job holding shape. The concealed pocket also is a nice touch, one thing I would change about it would be to have it be a sweat resistant pocket. I have the blue jersey and it has sharp clean lines and no over the top branding which I prefer. There is a good amount of reflective elements to give you some visibility on the road.

Back View

Overall ★★★★☆

Overall I was impressed by the Smartwool Flagstaff Jersey. I was pleasantly surprised that even with 25% polyester in the mix the jersey still kept all the main attributes of wool. The fit was descent and I like the appearance.  I wish that the production of these was in the US. This jersey is a good alternative to the synthetic options out there. It will still retain its shape and has a slimmer fit. A good option for days when a short sleeved jersey is needed and it is not a scorcher. As always, your mileage may vary.


  • Made out of wool
  • Odor-free
  • Maintains shape


  • Concealed pocket is not sweat-resistant
