All my fingerless cycling gloves developed a few loose threads the first year but overall lasted well for years. I'm still using a set of inexpensive Garneau gloves from 2015 or '16, no problems. Even a very thin set of Giro minimalist gloves are still holding up despite a couple of loose threads -- the seams didn't continue pulling apart.

These have held up much better than the old school leather and crocheted gloves I wore back in the 1970s. Those things never lasted more than a year or two.

If I had my druthers I'd get a non-existent pair of Bontrager gloves: a fingerless version of their now-discontinued cool weather full finger RXL Thermal gloves. Toughest and most comfortable unpadded gloves I've ever found. No loose threads, unraveled seams, or structural deterioration at all. Even after a few minor slips and falls there's nothing worse than minor scuffs on the leatherette palms.
