We’re proud to introduce the 4th generation our Alpha Jacket. Our best jacket, just got a whole lot better!

I know what you’re thinking… “what’s different compared to the old Alpha Jacket”? We’ve spent the past 2 years riding all over the world, taking notes of ‘all the small things’ that we could improve. More importantly, we listened to YOU. Your emails and reviews had some hidden clues on ways we could improve the design… and we’ve been paying attention.

STAY PROTECTED
We’ve stuck with the classic Protective Maxtex® 600 D outer shell for superior abrasion resistance. For added protection, we’ve designed the jacket to be 100% compatible with body armour inserts for the back, shoulders and elbows (sold separately). NEED ARMOUR? CLICK HERE.

STAY COMFORTABLE
Cold weather? We’ve improved the removable Thermoline® thermal liner, plus added built-in wrist gaiters to help block cold wind from entering your sleeves.

Warm weather? Zip-out that thermal lining and open the new SmartVentTM System (with a total of 5 zipper vents) for maximum air circulation, keeping you cooler.

With a total of 5 large pockets, you’ll have plenty of room to stash all your valuables on your next ride. We’ve added a magnetic keeper to the removable hood (to stop it flapping around), there’s a hidden key clip in the front pocket for your key/fob, reflective logos for extra visibility and premium YKK® zippers all round.

STAY DRY
Built for the worst conditions – Fully seam sealed + our new Humax® membrane features a huge 14k Waterproof + 19k Breathability rating, resulting in the ultimate protection against rain, wind and snow. (14,348 mmH2O + 19,241 g/m2/24 h)

STAY OUT THERE
We’ve built the new Alpha Jacket to take you wherever you want to go. From mountain peaks, to city streets. Around town, or around the world. The Alpha 4.0 Motorcycle jacket is ready for it all.

WHAT SIZE SHOULD I GET?:


The Alpha Jacket has ZERO stretch. We recommend that you choose a size that will fit 'loosely' on your body.

The best way to find out your size is to measure a jacket you already own, and that fits 'loosely' while on your bike (factoring in any garments you wish to layer underneath). Being a lot thicker than most other jackets this adds to the overall chest width of the jacket. We encourage customers to measure something that's a similar style (such as a snow or a thick technical jacket) as this will ultimately be the best comparison in chest width.

Measure by laying your jacket flat on a table, and measure the chest, making sure to go from side seam to side seam (near the armpit like in the photo below). It's very important that you reach the seam join on each side, even if you have to bend a little around the sides of the jacket. Compare your measurement to the size chart above.

If you're unsure of your size, please EMAIL US at support@akinmoto.com, especially if you are an international customer. We are here to help and will do whatever we can to make sure you order the right size.

Model in the photos is 6ft, 83kgs, has a 100cm chest and is wearing a size Large.

Best damn jacket

I don't own a car, and I ride 24/7, 365. I've tried many a jacket but none can compare.

The Alpha jacket is warm, comfortable, and stylish. I also really appreciate the wrist gaiters. Now I have to try to justify buying the akin gloves and pants

Thanks for such an incredible review! We're so stoked to hear how well the Alpha Jacket is performing for you! If we can help you with any info or size guidance for either the Alpha Gloves or Pants please feel free to reach out to us at support@akinmoto.com

Happy customer.

I bought both the Alpha Motorcycle Jacket 4.0 and Alpha motorcycle pants. I got the sizing wrong; Grant was extremely helpful with the exchange to an X-Large. I’m 185cm tall and 85kg. The Large was a bit tight. If you’re unsure about your sizing email Grant before ordering which saves time and effort. I spend 10 hours on the road back from WSBK Phillip Island yesterday and I was comfortable all the way home. Thanks Team Akin!

Thanks for such a great review D! That's so awesome to hear how comfortable the gear was on the ride back from Phillip Island and I'm stoked that we could help you out to get the right size gear. Definitely for anyone chasing the perfect size their best bet is to email us first and we'll happily help out. Cheers again! - Grant
