A full-face snorkel mask includes a mask assembly having a breathing chamber and a snorkel assembly having a fresh air intake channel and an exhaust air discharging channel. The fresh air intake channel guides fresh air into the breathing chamber and the exhaust air discharging channel discharges waste air from the breathing chamber. During snorkeling, fresh air is supplied via the fresh air intake channel to the breathing chamber for a user and the waste air exhaled from the user is discharged from the breathing chamber to the exhaust air discharging channel. Therefore, fresh air is separated from the waste air to prevent the user from repeatedly inhaling the waste air in the breathing chamber.

A water paddle used for surface and underwater swimming, snorkeling, water aerobics and other water exercises. The water paddle includes a hand held, lightweight, flexible plastic, hydrodynamic paddle disk. A front of the paddle disk is flat or concave in shape for increasing or decreasing water resistance when moving the paddle in the water. Also, the paddle disk has a minimal thickness of ⅛ inch or less for allowing the flexing of the disk. An adjustable strap is received through a pair of parallel strap slots in the disk.
