A great technical MTB Outdoor jersey which keeps the wind out and provides super ventilation so you won't overheat


  • When we introduced this concept to the MTB press 6 years ago, they weren't sure about it. Now this combo of wind and waterproof front and jersey back is commonplace because it works!
  • This is a super versatile warm jersey that doesn't over heat
  • The windproof and waterproof front protects you from the elements and the jersey back allows maximum wicking and breathability so you won't overheat or get clammy 
  • Tested in Scotland by our co founder and original Fat Lad Richard, it got 10/10
  • Great for cycling, walking or all outdoor activities
  • Short front collar zip for ventilation and ease of getting on and off
  • Smart design that'll look good on the trail and at t' pub after
  • Wear with our Cracking Shorts



Our Outdoor Tech T's and Outdoor MTB jerseys have a looser fit than our road gear, HOWEVER after feedback that sizing on our 2022/2023 MTB tops was TOO BIG we have adjusted the sizing of the new OUTDOOR Technical collection and now our Outdoor MTB and Outdoor Tech T shirt sizing follows the same measurements.

PLEASE take a look  👀  at the measurements chart below BEFORE ORDERING and compare to your previous MTB purchases 📏

Half Chest

To get an accurate half chest measurement, hold your garment just under the arm pit with each hand, give it a quick shake and then carefully lay it on a flat surface. Measure from arm it to arm pit at its widest point. This is the half chest measurement.  

    Top Tips For Getting The Right Size

    1. Get measured before you order
    2. Measure your chest and belly at their largest point and order the size which corresponds to the largest of the two measurements 
    3. If you have MTB tops from previous years collections, the sizing has changed so please compare the new measurements with your existing kit 
    4. Size 54/58 is available in our Big and Tall collection 
    5. Drop us an email with your measurements if you need some help
