Harbinger gloves are IMHO overpriced. Also its leather is made from pig skin lining, so not a good idea if you're muslim. Nike & Adidas are also overpriced, you're paying for the name, not much of the quality. I'm personally wearing some no-name gloves bought for 30 bucks, does the job just nice, no issues.

I've been using gloves for like 80% of my gym years. It minimizes calluses. But now i'm considering for some grip pads instead so i don't get this 'tight' feeling on my upper hands.
