Sometimes when you thought trunks would suffice, the swell brings in a little bit chillier waters. Thankfully you can stash the XCEL 2/1mm Axis Long Sleeve Wetsuit Jacket in your bag and quickly/easily throw it on for a boost in core warmth! 2mm neoprene in the front and back body provide extra warmth, while 1mm sleeves and gussets ensure paddle-able dexterity.
