Seek only the best times.

The best days start by getting kitted up for a ride, and end with the clink of frosty mugs with your crew. To make the transition from start to end a bit smoother, Ion crafts the Seek Amp Short-Sleeve Jersey from Drirelease fabric that seamlessly moves from the bike park to the brew pub thanks to its clean cotton look, and naturally wicking properties.

Cut relaxed so you can move around on your bike, the Seek AMP Jersey is ready for shredding. The tech-tee feel provides moisture-transfer that pulls sweat away from your skin as you work, and feels as soft as your favorite well-worn cotton tee. To keep your vision clear ahead, the jersey comes equipped with a microfiber lens wipe to let you polish up your shades trailside before you book it down into town to meet up with the buddies to shove copious amounts of pizza down your gullet.

  • A tee-styled jersey for heading from trail to town
  • Drirelease fabric boosts you with breathability
  • Soft cotton feel, like your favorite tee
  • Fabric dries 4-times faster than regular cotton
  • Built in lens cloth lets you keep your specs fresh

Not a fan of the design

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

If you don't like the design on the sleeves, I would check out the Seek DR Short-Sleeve Jersey - Men's. This is a fine t-shirt with fit, feel of fabric, etc. I just didn't care for the design.

Like your softest tee shirt

  • Familiarity: I've put it through the wringer

Except it dries a lot quicker and does a surprisingly good job wicking sweat. It's breathable for a tech tee but I would not recommend it for rides where you will be pedaling all day and sweating it out on long climbs. It's more of a bike park, shuttle laps, or go for a quick evening ride and hit the pub type of jersey. Not flashy like most mtb jerseys, just a nice high quality riding tee. 5'11 190 lbs with about a 42-43" chest and XL was a good fit. If you're between sizes on the chart I'd probably size up.
