I have always used the Koral VT-Pro shorts and I love them. Comfortable and durable, but the velcro wears out after time. My urban camo ones barely stay closed anymore. I have to go find some really strong velcro and sew it into them.
I recently bought these Koral shorts and I LOVE them. The waist is a neoprene, while the material is rip stop. Very comfortable, very durable, although shorter than most shorts.
