Regular Liner vs. Tall Liner

Our tall styles are for you if regular-sized shirts fit in the chest and shoulders, but the body length and sleeves are often too short. Tall Liner is 2" longer in the body & 1 ½" longer in the sleeves.

Measuring Tips

Here are some tips to help you order the correct size. If you don't have a measuring tape, use a piece of string and hold it alongside a ruler.  (for men, if you use your t-shirt size you should be right on)


Lift your arms slightly and measure around your body, crossing over the fullest part of your chest.


Measure the outside of your clothing at the waist.


Place your hand on your hip with your arm bent at 90 degrees. Measure from the middle of the back of your neck, across the shoulder, and down your arm to the wrist.

Very Disappointed. Sleeve length is way too short for motorcycle riding. Product keeps you plenty warm but not for anyone wishing to use for riding. HIGHLY recommend the manufacture start making longer sleeves or a tall version. Other good product.

Awesome jacket liner works great

If you want to stay warm or hot look no further! In 15 degree weather not including windchill and 75+ mph speeds in Colorado winter snow I stayed plenty warm and only had the heat about halfway. This jacket will definitely keep you warm on those cold rides no matter how short or how long you ride. Great fit, and comfortable even after you get off the bike and are just walking around. A must have for year round riders in freezing weather and still want the ability to move comfortably instead of being bundled up.
