I sell all the big glove brands and it seems customers have very different opinions on what's best, I think it comes down to how the glove fits your hand and expectations. I see people complaining about seams and some recommending washing the gloves. You can certainly wash them, but given how extremely thin the fabric is, it's going to wear the glove even faster. How careful you are when taking off or putting on the glove also determines the lifespan. I see
@slide13 mentioning lifespan of a year, I would consider that high, even if you are carful, but obviously how much you use the glove will have a huge impact on lifespan. If you're a regular player that plays a few times a week and you don't rip the glove off or force your fingers in the glove when putting it on, I think 6 months is realistic. Pay attention to the width of your hand or if you have very thick fingers, some gloves will easily accomodate this, while other will rip in the seam, so you will most likely have to try a few different ones before finding one that works for you.
