Good ole IRC
I've been using IRC tubes and sometimes tires for over 25 years. Without going into detail, I raced KTM's for 20 years and never was stranded or broken down due to IRC products. VERY DEPENDABLE and I buy again.

Great IRC Quality
Needed a replacement tube that could handle the gnarly rocks and roots I ride over. Tube is heavy duty and very thick. Stem feels like good quality and has good hardware for holding the stem in place. Installation was definitely more difficult than a thinner tube, but no where NEAR as hard as I had imagined. Was just a little careful and did my first solo tube change with one of these and no pinch flats.After installing I made sure to inflate the tube juuuust a bit so it expanded into the tire and that made all the difference. I also took my time in reinstalling the tire and was super careful with my spoons.Definitely recommend.

Different valve cap
Didn’t come with valve cap shown, was expecting a core tool cap (reason why I purchased these tubes), came with a standard cap.

It Is Working Great
I decided to get this when I got a flat on my rear tire. The original inner tubes were factory, so they didn't have any reinforcement ... and my bike had some crate damage during shipment, so I am wondering if the flat that I got was due to that. Thus, I did change out my inner tube at home, and the installation was no problem. At any rate, I've put 3,000 miles on my bike, and the inner tubes are working great. For the price, I would recommend.

These Socks Rock !
These socks rock ! I love them because they are tall & just the right thickness for riding my motorcycles. Street or dirt bikes, winter or summer you can't beat the price on these things. When I am riding my street bike back & forth to work at night, they keep my shins warm when I'm wearing 8" duty boots & when I'm riding my motocross bikes I can almost pull them all of the way up to my knees to keep my high motocross boots from chafing my legs. Never to hot or cold, these socks do what I need. I have bought them 3-4 times so far in the last five years and as long as they keep making them, I'll keep buying them. I sincerely recommend these socks to everyone who rides bikes or likes to wear tall boots ! ;-)
