Product Details


Description for Firstgear 37.5 Men's Kilimanjaro Gray/Black Jacket

The FirstGear 37.5 Kilimanjaro jacket is our newest, high end, waterproof breathable shell. Performance shell jackets are the perfect outerwear option to add to the rider's base layers creating an optimum microclimate. Our 420 denier nylon outer fabric was chosen for its balance of lightweight, suppleness and outstanding abrasion resistance. Added to that we have extra abrasion resistant, 620 denier, nylon at the elbows, upper arms and shoulders. Durable stretch fabric at shoulders makes for bind-free riding.

The 37.5 Kilimanjaro jacket is named after the 37.5 waterproof and breathable barrier. This 37.5 laminate significantly improves the comfort and performance of this technical outerwear by using micro particles to accelerate the capture and release of moisture vapor which helps keep you cooler when it is warm, warmer when it is cool, and above all, dry.

Water is kept out by the chassis fabric, rolled neoprene collar with hidden, under helmet, hood, storm flaps, waterproof zippers, six arm/wrist adjustments and our drop tail cut.

Featuring D3O brand, CE certified, armor padding at the shoulders and elbows as well as chest panels to provide additional impact protection. D3O brand EVO T5 back armor is far more supple, breathable and comfortable to wear while still being CE certified for rear impact protection. D3O is light and flexible with extraordinary energy absorption properties. FirstGear was a first adopter of D3O and we are proud to expand our use of this extraordinary technology in the Kilimanjaro.

Great service and a quality product. I own several Firstgear items and this jacket did not disappoint. I'm 6'04" and 250 lbs. Ordered the 3X and the jacket fit well after adjustments. Since there is no thermal liner be sure to layer up. I rode in 35 degree weather recently and had no issues with the cold weather.

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.
