US at (Triathlon) legal (unless otherwise deemed by race director)
Open water swimming for freestyle, breast, butterfly and side stroke
The Powerbreather takes fresh air from the top, while you exhale from the bottom, making it 100% pure oxygen, not mixed with Co2 like traditional snorkels.  The tubes bring air in only, no water, so you do not need to clear the tubes of water, just inhale normally.  Ideal for distance swimmers, those learning proper stroke, up to professional level trainers.  Works in open water, Ocean water with rough conditions, and even flip turns in a pool. The sport PB0101 does not include the accessories for aid in flip turning.  The lap PB0101 has all accessories except the extended speed vents for waves or sinking low in your stroke.  The wave includes everything. Kit contents: 1x Powerbreather PB01; 2x speed vent s (standard); 2x flip cap (for flip turn or open water); 1x blind cap (for flip turn); 1x case  .
