Defend Delta Long-Sleeve Jersey

With the cooling technology of Polartec Delta fabric, the Defend Delta Jersey is like having a built-in radiator, regulating your body temp as you transition between lung-busting climbs and high-speed descents. The material offers quick dry times and better breathability when wet, making this jersey suitable for a wide range of conditions. And with abrasion-resistant Cordura sleeves, you won't need to worry about overgrown trails or low-hanging branches snagging you as you ride past.

  • A lightweight, comfortable, temp-regulating MTB jersey
  • Polartec Delta fabric is wicking, quick-drying, and breathable
  • Relaxed fit provides a more natural range of motion
  • Cordura knit sleeves are soft, flexible, and abrasion-resistant

Weird fit

  • Familiarity: I returned this product before using it
  • Fit: True to size
  • Size Bought: Small

I liked the materials this shirt was made of, but the fit was weird. The body was a perfect fit but the arms were super tight, like a spandex shirt. I don’t have super big arms either. I wish the sleeves fit me like the body did. Had to return, sleeves were uncomfortably tight.

Polartec Delta is the real deal!

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: M

I was skeptical of the tech, yet needed a long sleeve shirt to try and keep my arms from getting banged up, so I decided to give it a shot. I wear this thing out on all my rides now, and have even bought a second one in another colorway. The Delta fabric keeps me cool, even in the hot/muggy heat of summer out in the West Virginia back country, and the Cordura sleeves hold up to getting hit with brush or the occasional fall to the dirt.

Were the sleeves tight?
