MamaNest™ S21 SmartWear Breast Pump
MamaNest™ S21 SmartWear Breast Pump
Most pumps guess at suction. The S21 SmartWear shows you exactly what's happening — with a smart LED display and two flange sizes to fit your body perfectly.
Ill-fitting flanges are the #1 reason mums get less milk than they should. The S21 comes in 24mm and 27mm to match your anatomy — because a proper fit means more comfort, better suction, and stronger output. Add a bright LED display showing your current mode and suction level, and you're no longer guessing — you're in control.
Which size and config is right for you?
24mm flange: Best for smaller or average nipple diameter (most common). Start here if unsure.
27mm flange: Better for larger nipple diameter — reduces friction and improves output.
S21 (single, $60.71–$62.26): Great for mums who primarily nurse and pump occasionally.
S21D (double, $100.52–$102.09): For exclusive pumpers or mums returning to work — halves your session time.
