Just got back from a week of diving dry in Bonaire (33 dives in 6 days), where my buddy and I were teased relentlessly by nearly every other diver on the island. Even the folks that cut their own Town Pier night dives short because they were cold made fun of my DUI 30/30 "tropical" dry suit!
As comfortable in 80F UNDER water...
...as it is in 85F ABOVE water!
My trusty DUI 30/30 has been to Florida (3x), Hawaii (2x), Curacao, St Kitts, Grand Cayman, Little Cayman, Cayman Brac and now Bonaire. After almost 100 dives in 80F water with the suit I can assure you that dry is the only way to dive! (In fact, since buying the 30/30 the only time I've worn a wetsuit has been in an indoor heated pool!)
