Full seat! Some full seat breeches are so uncomfortable so I see why some people would prefer knee patch. I LOVE my fits breeches!!! They're the best thing that has ever happened to me! They're super grippy! And they're really thin, so they're cool in the summer and surprisingly warm in the winter! And the most comfortable pants EVER! Honestly I don't take them off after I ride because they're so amazingly comfortable!! Bit pricey... but they hold up well and are totally worth it! The ones I have are the perforMAX all season. I haven't tried their other breeches but this one is my holy grail!
