Medela Pump In Style Breast Pumps & Accessory Kits

For a nursing parent heading back to work or building a milk supply at home, the pump has to keep up without becoming another chore. The Medela Pump In Style line is built around exactly that reality — efficient double pumping, two-phase expression that mimics a baby's natural rhythm, and a design discreet enough to fit into a workday.

The Medela Pump In Style Advanced Breast Pump Kit (101036445) arrives ready to go, with the pump, breast shields, bottles, valves, and an insulated cooler bag so expressed milk stays safe from desk to daycare. Two-phase expression starts with faster stimulation cycles to trigger letdown, then switches to slower, deeper cycles to maximize output — a difference many parents feel in both comfort and volume during longer sessions.

Because valves, membranes, and shields wear out or get misplaced faster than the motor does, we also stock the Medela Pump In Style Accessory Kits (87250). Keeping a spare set on hand means a torn membrane or a lost valve never sidelines a pumping schedule. It's worth confirming your shield fits properly — a size that's too large or too small can reduce output and cause soreness — and replacing membranes regularly to preserve suction strength.

All Pump In Style bottles and connectors are compatible with the standard Medela system, so the parts you already own generally work together. If you're assembling a fuller kit or need spare bottles, tubing, or storage, browse our broader Breastfeeding & Pump Supplies collection to round out everything you need for pumping at home and on the go.
