Gem Wearable Breast Pump

The Gem Wearable Breast Pump is a handsfree, in-bra pump designed to make expressing milk fit around your day rather than the other way around. It sits discreetly inside your bra with no wires, tubes or plugs to manage, so you can express while getting on with things — whether that's a work call, a nappy change, or a quiet moment to yourself.

Because it's battery operated, you can pump anytime and anywhere without hunting for a plug point. A built-in digital display makes it straightforward to switch modes and adjust intensity, and the whole unit runs at a sound level below 50 dB, which helps keep expressing low-key when you're around others.

Modes and control

The Gem offers four mode functions — Stimulation, Massage, Expression and Ultra-expression — each with nine intensity levels, giving you room to find a setting that feels comfortable for you. It expresses at a lactation frequency of 55 to 95 cycles per minute and a lactation intensity of 100 to 270 mmHg, adjusted through the display.

• Stimulation and Massage: Lighter, faster settings intended to encourage let-down at the start of a session.
• Expression and Ultra-expression: Stronger settings for drawing milk once your flow has started.

More settings won't determine how much milk you make — output naturally varies with time of day, recent feeds and your own body — but having adjustable modes and intensities makes it easier to dial in a rhythm that suits you.

Cleaning and materials

The Gem is made with food-grade plastic and silicone and is BPA free. It's designed to be easy to take apart and clean, and can be sterilised using steam, UV or boiling below 109 °C — so you can choose the method that fits your kit at home.

Power and charging

A 1500 mAh lithium battery powers the unit, recharged via the included USB-C cable, and it runs at a rated 5 V and 3 W. The USB-C charging means you can top it up from the same chargers you likely already use — handy for travel, commutes or working around load-shedding.

What it comes with

The Gem is available as a Single or Double set, so you can choose single-side or double expressing to suit your routine. Each unit comes with a 150 mL milk collection bottle and lid and a USB-C charging cable, so you're ready to express out of the box. Replacement and spare parts are available too — including collection bottles with lids, silicone diaphragms, duckbill valves, silicone flanges (18 mm, 20 mm and 22 mm) and a 24 mm breast shield — which makes it easier to keep a working parts rotation and find a comfortable flange fit.

How it Works

• In-bra collection: The pump and collection bottle sit together inside your bra, so there are no external tubes or bottles to hold during a session.
• Two-stage pattern: The mode functions move from lighter stimulation-style settings to stronger expression settings, letting you change the operating pattern as your session progresses.
• Soft milk-path parts: The silicone diaphragm and duckbill valve help the pump hold its vacuum, and both are replaceable when they show wear.

Best For

The Gem Wearable Breast Pump is a great option for parents who:

• Want to express handsfree while moving around, working or caring for baby
• Value a discreet, in-bra format that runs at a low sound level
• Need a battery-operated pump they can use away from a plug point
• Prefer adjustable modes and intensity levels to find a comfortable setting

It may not be the best fit if you:

• Prefer to watch milk flow into a bottle as you pump
• Want a mains-powered setup and don't mind staying near a plug

Pandylane Pro Tip: Flange size makes a real difference to comfort and how well the pump seals — and it isn't reliably guessed from bra size. Since the Gem's silicone flanges come in 18 mm, 20 mm and 22 mm (plus a 24 mm breast shield) as spares, it's worth measuring your fit so you can order the size that's most comfortable for you.
