I bought these for a trip to Morocco and believe that I definitely made the right choice and they were the envy of a few other riders while we were there.

The huge thigh vents work brilliantly and kept me cool (or at least bearable) through 40+ Celsius heat.

They are extremely comfortable while riding, with ribbed stretch panels and soft mesh areas front and back of the knee, with leather panels in the seat and inside, lower leg. A highly breathable panel around the groin also helps things a lot.

The zip, fly poppers, leg velcro and velcro waist adjusters are all very high quality and the clip loops, big pockets and key clip are all great little details - as is the lip in the pockets, so coins don't just fall out. These are cut to go outside MX boots, but I wore them both inside and out as the adjusters go right around the back of the calf, Klim also make a cut for inside boot only I believe.

I rated reliability high since I rode 6000 miles and put them through a fair amount of distress and there are no signs of anything failing, only time will tell how durable they are.

I did find that I missed waist level pockets, but that was just a case of adjusting my habits.

Without additional armour, their protection is somewhat limited, but the foam padding is comfortable to walk in and offers some protection. They are good for light showers and even brief, heavier showers, but obviously will need a waterproof layer in anything heavier or more sustained.

Would definitely recommend for comfortable hot weather riding and would definitely consider buying again.

Bought them from Desert Rose Racing (via Adventure Spec) - recommended.

Superb trousers for riding in hot places. 20" zips on the thigh open up to vent the leg, with a permanent mesh section below the pocket / underside of the thigh.

Bottoms open all the way to the knee, with multiple velcro sections to secure the leg once you've got your boots on.

Leather on the inner legs to protect from heat.

Big enough to get proper knee braces on (I wore EVS Vision)

Two decent sized pockets, one with a snap lock for your bike keys.

Heavy duty Cordura, and some really good stretch panels on the groin.

My only criticism is that there are no belt loops or rubberised liner round the waist, so tey do tend to slip down slightly. Having spoken to Dave Lomax (Importer) they are fitting belt loops on the next version.

Bought them from these guys - can't recommend highly enough:
