Question: Could these be comfortably worn over a pair of jeans or pants made out of tough material?
Document: Nice knee pads. I really like the way the knee pads attach with the alta lock for quick on and off. Primarily purchased to use while hunting. Appear comfortable when worn over pants. Also like that they are flexible and are made of hard rubber that don't slide while in use. Can't wait to try them out this year while turkey hunting!
They are a sturdy but flexible, hard rubber material with a soft texture to them that provides grip when kneeling down.The lower strap is made of a tough and durable adjustable Du Pont Cordura (R) strap. The upper strap is made of a flexible elastic strap that gives enough tension to keep the fit around the lower quads/above the knee nice and tight without hindering range of motion when bending at the knee.The "Altalok" buckle system is simple to use; they slide in and out easily and are designed in such a way to eliminate any accidental loosening of the strap.
So far these are the top rated knee pads for tactical use. The hook system is far better then the velcro. Worried a bit during long running that the  knee pads may slip or slide. It is almost that I need to sew loops in my pants to keep these in place. The none skid does help. If you know of a better product, let use know. Not sure what generation this is, but maybe, could be next generation of these knee pads would be better. I need a pair of these with the hook system for my elbows...
Wearing these over pants I could not get them to tighten down enough. I'm an average sized man and the knee pad was big enough that I had to Macgyver it to be any use at all and it still ended up around my ankles after 15 minutes of use. If you want something for a costume or very light use, go with these, otherwise you're better off getting something a little higher quality.
I'm an auto technician and I use these everyday at work. They have a thick pad that keeps my knees off of the hard concrete when I need to kneel or crouch for some reason. I find that I'm constantly having to pull them up and adjust the straps if I do any amount of walking, it's not a deal breaker for me but it gets annoying real quick. I suspect that may be they don't stay put for very long because I wear them with Dickies style work pants. Anyone that wears those kind of pants knows that the material is kind of slippery, and the straps/inside of the knee cups can't get a good grip on them.
Good padding so it protects your knees very well.The top straps are elastic and bottom straps are simple nylon straps.The straps are sewn into the nylon material cover, so under intense abuse, they could potentially rip out of the material.The buckles are of interesting design and simple to use. Each pad is identical, so the buckles are on the same side. Many other designs place them on the opposide side, as right / left. For this product, this is not the case. No biggie.The plastic shield provides good protection.There is no perfect knee pad but this does the job quite well.
These knee pads are light but tough.The straps have well made buckles on them so you do not have to adjust the strap length every time you put them on. If you're low crawling, they can slide around a little, but not so much that they can't be readjusted easily. They are comfortable to kneel on repeatedly. What they sacrifice in padding support, they make up for in lightness.
I purchased these pads to use for paintball when the foam in my other pads went kaput. Knee pads are essential where I play due to hard soils and rocks, and these worked beautifully. I dropped hard on my knees several times and never had a "I wish I hadn't done that" moment.They're worn on the outside of your pants, so like all pads of this type they can bind up a bit, but I had very little problem with that, to be honest. The benefit of that though is the hard shell keeps your pants from getting destroyed even while the back gel protects your knees.
I purchased the Alta Superflex Knee Pads with the non-velcro "Altalok" buckle (featured in the photo).The packaging states clearly "not intended for athletic applications", but I could see it being used in outdoor sporting activities (the reason for my initial purchase). After adjusting and wearing them, they are quite comfortable. The disclaimer is probably because the cushioning is not as thick as other cushioning found in volleyball or similar knee pads available, but make no mistake: there is comfortable fabric and great padding in these.The cap is not a super-rigid, plastic material like many skateboarding caps are.
I won't do remodeling without them... wish I could say I would buy another pair but these are holding up great -especially at this price!
