Sorry to bring up an old post in the thread Wes but I was looking at picking up a pair of Twins shorts and the sizing chart on the product page seems to conflict with what you told me earlier. Could you please confirm which is accurate?
From the product page:
TWINS THAI STYLE TRUNKS BLACK > Shop By Brand > Title MMA
Size / Length / Weight / Waist
Small / 17" / 90 - 112 Lbs. / 24" - 26"
Medium / 18" / 112 - 132 Lbs. / 26" - 32"
Large / 19" / 132 - 165 Lbs. / 32" - 34"
X-Large / 20" / 165 Lbs. - Hvywt. / 34" - 38"
XX-Large / 21" / Super Hvywt. / 38" - 40"
