I got these going into fall because they were pretty cheap and claimed to be waterproof. I commute year round in the greater Seattle area so waterproofing is a big deal. It's now Decemeber and these haven't let me down yet. I have ridden through heavy downpours and come out dry. That said, you do need to keep up on the wax for these to really be effective. The crotch area especially, if you're riding in the rain every day you will need to re wax these every month or so. I use penguin wax but any brand will do.

I was surprised these came with hip armor, seems like it's never included even on the more expensive pairs. It's not the cheap stuff either, it's the kind that's soft and maliable until impact and then it hardens, makes it comfy to wear. The knee armor is not adjustable but it's in the right place for me. I wear a 32x32 in Levi's, I'm 5'11" and 170lbs, the medium fits me well. The waist is a little tight and has no elastic so if you're a big guy you may want to steer clear, I wouldn't call these form fitting, but they're definitely not relaxed either.

All in all these are great for 2 to 3 season cold weather, they seem to be built well and are fairly warm, definitely to warm for summer and probably spring in somewhere like California. For winter/fall they're awesome.
