I have delicate knees, always need kneelers, and like many users of same have trouble finding ones that a], are comfortable and b], will stay up for more than 5 minutes of wear!!
Saw these, liked the Irwin name, and liked the look of the way the straps were attached, so gave them a try.
They arrived, with a tag saying "Irwin Industrial". Industrial? - huh! - toytown more like. The thin fabric cover separated from the [flimsy] padding within 2 hours [!] of first wearing them, by the end of a week of light ocassional use they were useless. The desperately inadequate internal padding had come away from the wrapping, the straps already over-stretched, flimsy flimsy flimsy!
"Professional" Knee Pads - someone is taking the mick here!
So back to the good old pair I bought 6 years ago for £6, and have patched many times, which were still 10 times better than this feeble offering.
By no means the only uncomfortable and relatively ineffective kneelers out there, but by far the worst I've ever encountered for longevity.
Irwin, you should be ashamed to put your name on these.
