I have several pairs of inexpensive gloves from Amazon and a pair of Pearl Izumi. All I use these days are the Pearls. About once a week I throw them in the washer. Riding between 100 and 150 miles per week, mostly road or trainer but some mountain bike.
I have found that when I use the Pearls I can ride 40-50 miles and little hand discomfort, but 10 miles on with the inexpensive Amazon gloves my hands are in pain. If I only did 10 miles rides I probably would just go bare handed or be happy with the $12 Amazon gloves.
