I spent the 2010 summer canyoning in Europe, both guiding and recreationally
. The European canyoners grunted through the canyons in 7mm one piece or 5mm two piece suits. I danced through the canyons in my Seventhwave Viper 3/3
— what a dream it was, with many envious onlookers! For the glacier-fed canyons I was toasty warm with a Hot Top
and neoprene shorts underneath and comfortable from start to finish. Cheers Seventhwave!
