Klim makes two different “cuts” in their K Fifty jean line… the K Fifty 1 which is the more relaxed jean and and the K Fifty 2, which is more of a “classic” jean which is more tapered through the thighs and legs (see the link below to visit the other K Fifty jean version). Other than the cut, the jeans have the same feature list. I’m impressed with the ruggedness and the straightforward nature of these jeans. Basically these are very heavy duty denim jeans with plenty of D3O armor. They are premium in materials and construction.
The K Fifty 2 jeans, sold on this product page have a classic cut which is more tapered in the legs and thigh. Younger riders and generally more thin folks will probably choose the Fifty 2 cut. They aren’t “skinny” jeans, but they aren’t relaxed like the Fifty 1 version either. To make a Levi analogy, I’d say these are 501s.
The denim material used is thick but soft and is more than plain cotton… it’s a blend of cotton and nylon. The nylon improves the jean’s wear resistance if you fall. Also, the jeans have large reinforcement panels of Cordura® material in the seat and knees (like most other good riding jeans). The inside of the jeans is lined all the way to the cuff. The lining will keep the armor and Cordura® components from rubbing you the wrong way.
The pants have a FULL set of certified level 1 D3O armor in the hips and knees. Plus there’s even a little tail bone piece made of Poron XRD impact foam. The knee armor is in a pocket, but the height of the armor is fixed by a piece of Velcro that sticks to the mating piece sewn to the pant. So you can “stick” that armor at the height that fits you best. And there is a bit of wiggle room side to side too. Take a look at our studio pics and you can easily see the armor through the mesh liner. You can also see the patches of Kevlar too.
Another nice feature I notice is that the rivets and the main waist button are rubber coated to help keep your paint from being rouged up by an otherwise metal surface. Also the jeans have two belt loops in the very back (crack kills folks).
These jeans aren’t cheap by any means but they are rugged and well made and with the best armor currently offered in our business (IMHO). And all in a well fitting and comfortable package. :: Paul, 02-21-18
