I have a pair of small and im a 30 as well. Mine are from the riv garage sale so I'm really not sure if they're the same generation, but, I'd have to say the waist on the small is kinda tight, I usually don't clasp the buckle and it hurts my tummy if it rides up too high because the elastic is pretty tight. Also depending on what you use for underwear, how tall you are(I'm between 5'9-10, with 86pbh and long neck), or how short you like your shorts might be an issue, I feel like my balls are going to be visible sometimes haha, they're short And wide! But the air feels nice so it's a trade-off and it's possible they will fit you differently than on me.
It's worth mentioning this was my second pair. I had my first pair altered to be tighter around the thigh which then happened to rip the gussetted crotch part , so be careful with that. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
