Knee/shin pads for climbing?

Hey there! I’m looking to get some insight on potentially getting some knee or shin pads for climbing. I am a new-ish climber with my current grade limit being 5.9. I’m going out every single weekend and climbing as much as I can now that the gyms have been closed and also doing push ups every day to try and gain some more strength.

I know part of my issue is still being kind of a Gumby and not knowing how to climb right. However, I also have extremely low iron (3ug/dL) despite taking iron supplements almost 7 days a week and bruise like a peach because of this and they take weeks to heal. Basically, if I look at the rock the wrong way, I bruise. I’ve already seen a hematologist about it and they pretty much told me they’re not going to do anything unless it’s severely impacting my ability to function.

My arms do not bruise quite as badly as my legs which is why I’m considering padding for my legs over other areas. It’s summer and it’s hot and I want to be able to wear shorts and capris without people gawking at my severely black and blue legs. I also worry that constantly re-injuring the blood vessels in my legs could cause problems down the road. So please, does anyone have any suggestions for knee or shin pads for climbing?

I have some of the cheap elastic foam volleyball knee/shin pads, available at most sporting goods stores.

One brand is Franklin, but any will work.

Really no such thing.  For climbing anyway.   Knees are aid.  
But you have options.  From full blown hockey style knee/shin pads in one (not recommended) to volleyball style, to just something lower profile like a neoprene “brace” or support, to just feigning injury and wrap with an ace bandage.  
 Either way your gonna get gawked at and likely have a lot of wtf questions Thrown at you.   But your legs’ll look good in capris away from the crag

Check out the Pearl Izumi Summit knee guards.  They're low profile and lightweight.  I like them for mountain biking, they might fit your needs for climbing.

+1 for volleyball knee pads, they don't restrict your motion at all, and they're cheap. I use them for aid climbing. 

I've totally used thinner volleyball kneepads climbing, especially on chimney/offwidth heavy long routes. I've used the cheap square McDavid foam kneepads and they're great.

I've used something like the pearl Izumi knee pads like what TCC said for long routes, and while they don't fit my (k)needs as well, they might fit yours.

As an aside, the superficial bruising you're describing is unlikely to result in any long term issues (assuming all that's going on is iron deficiency anemia).  It's really just cosmetic, plus makes you look like you try hard.

Question: how are knees aid? ........also, at age 60, and climbing around 5.9, I don't care what people think of how I look, lol. socks under climbing shoes, gawdy shirt......people still always offering to belay me.......maybe they just feel sorry for the old guy.........

I'd say ditch the pads. This is a great opportunity to improve your technique since you actually have some additional consequences . If you're banging your knees and shins all the time it's due to sloppy technique (kneebars (unlikely on 5.9) and chimneys/off width excepted). I've always thought the adage of "climb quietly" was good advice, especially for beginners, who tend to stomp around on the rock.
