Power swimmers can now do the butterfly and speed swim without needing to come up to air with the Powerbreather Sealed Snorkel. That’s right, this is as close to being a fish as you can get with minimal gear. The sealed snorkel allows swimmers to remain submersed during their entire swim session workout. Fresh air is inhaled through a back pressure valve behind the head, while a second valve at the back of the head pushes out exhaled air. The best part? No water can intrude (unlike standard snorkels) so swimmers wont find themselves choking mid-stroke. The only draw back? A swimmer may resemble a cyborg monster (not every swimmer’s goal) but we think this can only up one’s cool-factor.
