Terrible Fit, but I'm sure protection is great.

Ordered the product after researching a while for a good comfortable fit Knee/Shin pad. I use this mainly for commuting. Comfort and protection seems great, even though i never wore this on the road yet. Design is great, looks nice, good ventilation ( tried it infront of a "Fast" fan at home).
The cons - too big to wear under jeans - you need a really looooseee jeans. Over the jean also didn't go very well because i wear a full boot under my jeans. The straps was the main let down for me - they are super elastic so i did not get a very firm feeling of them fitting me. The buckle feels very "plastique", and i wore it in my home for a few hrs and was walking around and invariable i had to adjust this every 5 mins. It kept sliding down, I imagine it would happen every time I'm at a stop light or sign on a motorcycle. You need to have very "Thick" legs for this to stay on properly.
All i kept thinking when i was wearing this is that if i get into a crash and land on my knees and i'm sliding face down. This will definitely rip off my leg and come apart.
I'm sure the protection is great coming from Alpinestars, but fit is terrible if you are a skinny person ( I'm 5'11" and 174 lb, medium built ). So I ended up returning this product and bought the MSR Reflex Knee/Shin Guard - I have some great things to say about this one. Check out my review on that product!!.
Revzilla was great, they shipped me the MSR the same day of the RMA and i got the product right the next day!!!!
