If you are planning to wear these pants over the top of your motocross boots, please get in touch with us before ordering. We will double check to make sure that they will fit over your boots.  


The Alpha Motorcycle Pants have zero stretch in the waistband, so you’ll need to take this into account when ordering your size. Please email us if you're unsure what this means!

We recommend following these steps to ensure the perfect fit:

  • Grab a pair of pants you already own (preferably a pair with zero stretch), and that fit you well.
  • Lay them flat, making sure the zipper and button are done up and the waistband is perfectly aligned (see photo below)
  • Measure the waist as shown and write down your measurement

Great stuff! Would be 4.5 stars if that were possible

Bought these a couple of months ago and I'm a fan!

I ride a fair distance to work every day Monday-Friday no matter the weather and was looking for some waterproof pants for the wetter days, which turned out to be no easy task. I'm pretty minimalistic style-wise and was put off by most rain gear which I always found too gaudy or plastic-looking.

After a bit of searching, I came across Akin and the Alpha Pants. I bought a pair from a local stockist and absolutely do not regret the purchase. An absolute winter essential for me!

I'm really into the more understated look of these. I normally avoid clothing with logos but the logo on one leg of these is so subtle that you barely notice it unless you're looking for it. Perfect for me in terms of style.

I've now worn these during some heavy rain and I can say confidently they're a tough and durable set of gear that protects you and keeps you warm and dry even if it's throwing it down.

And finally the price is a huge literal selling point and is more than reasonable. You can compete with these on quality but you'll be paying through the nose if you do. On the flipside, you can complete with these on price but I'm not sure you could rely on anything else as much as these if you tried that.

The reason I've not left a full five star review as I've found a couple of things maybe I wished had been done a little differently, but they're honestly minor.

First, I wish these could come pre-fitted with armour. I understand not everyone likes it and it is a bit of a pain having to buy armour you're never going to use, but I think maybe a pre-fitted armour option might be better since armour isn't always in stock. But this didn't end up being much of a problem for me anyway as I have a pair of riding pants with some SAS-TEC protectors fitted that I just took out and fitted into these. So really no harm done!

Second, I'm really not a fan of the press stud fastener at the top of the fly. It's a bit flimsy and it often pops open without much strain at all. Because I wanted to be able to wear other pants underneath these, I bought them in a Size M which is actually slightly big for me and feels a little loose when I'm wearing these by themselves. Even then though, I still find the press stud pops almost every time I get on the bike with these on. Usually not much of an issue but if you're riding in the rain, I can say from experience it's not fun walking into work in the pants you had under these with a big wet stain around the crotch area! I understand why the press stud is there since it creates a seal, but I would probably go for a different closure system given the waist is usually under a jacket and also the aforementioned water issue (to be fair though, that's happened only once).

Apart from that issue, I'm totally satisfied with these and am a happy customer. If not for the press stud issue, these would be an absolutely perfect 5 stars out of 5 for me. But either way it's a well-deserved 4.5/5 in my opinion. Definitely will be visiting Akin Moto again in the future - hopefully those Trusty riding shirts are back in stock when the weather warms up again! Cheers guys.

Pants and jacket

I wanted to write a quick review of the Alpha jacket and pants. I purchased the pants first and got the jacket a couple of months later. Both pieces are fantastic. They look great and I’ve commuted with them down to 23F and been warm. The customer service is literally the best I’ve ever seen. The jacket I purchased was sold out and they found one at a retailer and sent it my way. For Americans I’d say the sizing is euro—get a size up from normal. I’m 6’1” and 200 and the XL fits great. 10/10 would buy these again.

Bought these pants along with the Alpha 4 jacket. After numerous emails discussing sizing with Grant who was really helpful, I chose the pants from the measurements that I got from a pair of riding jeans that I already own. The size that was related to the measurement that I got from my pants indicated a size bigger than what I would normally wear, but decided to use the measurement as my size rather than the label size. When the pants arrived I found that they were a little big but after a small adjustment of the side tabs they felt comfortable without the normal gathering of extra material due to the size being too big to start with. The pants are of a high quality and felt comfortable and protective at the same time. Awsome customer service and great quality gear that looks good no matter where you end up wearing them.

Jacket & Pants conquer Nepal!

I did an Upper Mustang Moto tour in Nepal last month. I wore the Alpha Jacket and pants everyday and they were brilliant! We battled heat, cold, rain, mud, dust, water crossings.. everything .. and they stood up brilliantly. Thanks and congrats on great products!

Amazing Motorcycle Pants!

Amazing quality and finish. I tried quite a few pants from other brands, but none at this price point were as versatile. The pants are quite sleek and the fit is spot on. Great job team @AkinMoto!
