Description

This double-loop-shaped pull buoy is designed for swimmers to isolate the upper body during training. Placed between thighs or ankles, it immobilizes the legs to focus on arm strength, stroke efficiency, and breathing rhythm. Crafted from smooth, dense EVA foam, it offers buoyancy without absorbing water. The central opening ensures a secure, slip-resistant fit and helps maintain a hydrodynamic body position. Rounded edges and smooth texture prevent chafing during extended workouts. Compact and easy to handle, it is suitable for both beginners and experienced swimmers.
