Ride On.

We're all about getting our mountain biking season started early or extending the one we are currently in. Unfortunately fall and spring conditions can be unpredictable and luckily Fox gets this, and builds the wonderful Attack Thermo Jersey providing wind, water, and abrasion resistance. The shoulder seasons can sometimes be fickle and rides might not always end the way they started. During this time of year, versatile gear is critical. Don the Attack Thermo Jersey at the start of the ride and be ready for anything the mountain can throw at you.

This is mid-weight long sleeve jersey that aims to provide you with warmth and coverage to maximize comfort in colder climates. Whether you are while you are surfing leaves or testing the limits of cornering traction on some hero dirt, this handsome jersey will have you looking good and feeling great. The front of the jersey is wind- and water-resistant, providing insulation and rain protection without the bulk. If the heavens do open up and you end up needing a shell, the jersey features an offset zipper preventing stacked zippers and allows for easier use. The arms and back panel are breathable to prevent overheating and feature a DWR coating repealing water. If the sun does come back out or you are slogging up a precipitous climb, the full-length front zipper opens up to reveal a breathable stretch mesh panel for ventilation. Additional features include a silicone gripper at the hem preventing the back from riding up, back zipper pocket for easy access, and reflective logos for visibility.

  • Wind- and water-resistant long-sleeve jersey for chilly days
  • Moisture-wicking fabrics help regulate temperature

OK, but....

  • Fit: True to size
  • Size Bought: XL -- I think a L would have been fine.

I agree that it is really a jacket, but an odd one. It is warm and comfortable at first -- but, it doesn't breath. The thermal lining wicks just fine, but then it gets soaked and stays that way. The temperatures have been in the 40's, so maybe it will do better when it gets cooler and I don't sweat as much. We shall see.

Oddly Designed Jersey

  • Familiarity: I returned this product before using it

I love my Fox Attack Water Jacket, so I figured I couldn't go wrong with this jersey. I was wrong. First, it's hardly a jersey, but more of a light jacket. The fabric inside is a nice warm cushy fleece, except down the front, which is unlined, with a slippery fabric that is uncomfortable against the skin. It fits snug around the shoulders, but puffy in the front. (Are there THAT many fat mountain bikers?) It would be very difficult to fit a base layer under it, and who wears a base layer under a jersey? The sleeves are too short. The flimsy plastic zipper sticks at the bottom, and would not stand up to the hard pull it takes to get it to come open. I love Fox stuff, but not this jersey.

Comfy and warm

  • Familiarity: I've used it several times

Nice jersey for shoulder season and even heading into the winter. Pair this with a base layer and you could ride into December. Zipper is a little bit on the small and cheap side be nice to have a more hardy feeling zipper. Sleeves were a little short but not noticeable, I got a medium which usually works for me being 6ft and 150 lbs. It really is a toasty jersey surprisingly because it's really light weight. Will definitely be using this on all my shoulder season rides.
