Quick Answer
They solve opposite problems, so most Metro 3 owners eventually want both. Buy the Metro 3 Weather Shield first if you stroll in rain, wind, or snow with your child seated. Buy the Metro 3 Carry Bag first if your stroller spends more time folded in a car trunk, closet, or airplane hold than it does outdoors.
Metro 3 Carry Bag
These two Metro 3 accessories sit next to each other on the shelf, cost roughly the same, and get confused constantly. One goes on the stroller while your baby is in it. The other goes on the stroller while your baby is not.
That single distinction answers most of the question. The rest comes down to your climate, how you travel, and whether you already own the Metro 3 Footmuff or the Rain and Wind Carrier Cover.
What Each Accessory Actually Does
The Metro 3 Weather Shield is an all-season cover for the child. Ergobaby lists it as protection from rain, wind, and snow, with advanced ventilation for airflow, and coverage in all seating positions. It folds into the Metro 3 storage basket when the sky clears, so it lives with the stroller rather than in a closet.
The Metro 3 Carry Bag does nothing for weather. It keeps the stroller itself clean and scuff-free during travel and storage, using padded backpack-style straps that spread the stroller's weight across your shoulders. It rolls up small enough to fit in the stroller's storage basket, which means you can carry it with you and bag the stroller at the gate.
- Weather Shield: protects the passenger. Carry Bag: protects the stroller.
- Both store in the Metro 3 basket, so neither one has to be left at home.
Weather Protection: Where the Shield Fits
If you walk to daycare, commute on foot, or live somewhere with four real seasons, the Weather Shield earns its place fast. It covers all seating positions, so you are not adjusting it every time your toddler changes posture, and the ventilation matters more than shoppers expect: a fully sealed cover can trap heat and moisture, which is why Ergobaby built airflow into this one.
One limitation is worth repeating before you buy. Ergobaby states the Weather Shield should not be used when a car seat is docked onto the stroller. If your routine is car-to-stroller with an infant seat clicked in, the shield stays in the basket until your child rides in the stroller seat itself.
- Best value if you stroll in rain, wind, or snow with a child in the seat.
- Skip it while a car seat is docked; use it once your baby rides in the stroller seat.
Travel and Storage: Where the Carry Bag Wins
The Carry Bag answers a different complaint: a clean stroller that comes back dirty. Airline holds, trunk floors, garage corners, and rental car trunks are hard on fabric and frames. Ergobaby's bag uses wipeable fabric and padded backpack straps, so you can carry the folded Metro 3 on your back through a terminal instead of dragging it.
Because it rolls up small and fits in the stroller's storage basket, it works as an on-demand bag rather than a dedicated travel day accessory. You can keep it packed, pull it out at the gate, and stow it again on the other side. If your Metro 3 mostly lives in a car or closet between outings, this is the accessory that will get used most.
- Wipeable fabric means mud and road grime wipe off instead of soaking in.
- Padded backpack straps make a folded stroller far easier to carry than a handle alone.
If Neither One Fits Your Routine
Cold-weather parents often get more daily use from the Metro 3 Footmuff. It has a water-repellent exterior and premium fleece interior, an easy-to-clean internal wipeable panel, fits children 6 months to 4 years, installs easily, folds with the stroller, and is machine washable. That covers warmth and light weather protection in one piece rather than two.
If you carry your baby rather than push, the Rain and Wind Carrier Cover is the equivalent purchase. Ergobaby lists it as compatible with any Ergobaby carrier in all carry positions, water-resistant and lightweight, quick to attach and remove, and it stores compactly in a detachable pouch. Buying a stroller shield for a carrier-only routine solves the wrong problem.
- Footmuff: warmth plus weather protection for seated riders 6 months and up.
- Carrier Cover: weather protection when you are wearing your baby instead of pushing.
The Trade-Offs, Plainly Stated
- Weather Shield: covers the child, not the stroller: It handles rain, wind, and snow with ventilation and all-position coverage, but it does nothing to protect the folded stroller in a trunk or cargo hold, and it cannot be used with a car seat docked. Choose it if weather, not storage, is your daily problem.
- Carry Bag: protects the stroller, ignores the weather: Padded backpack straps, wipeable fabric, and a compact roll-up size make travel and storage easier, but your child gets no rain, wind, or snow protection from it. Choose it if your Metro 3 travels folded more often than it rolls outdoors.
- Footmuff and Carrier Cover: better fits for specific routines: The Footmuff adds warmth and light weather protection for seated riders 6 months to 4 years, while the Rain and Wind Carrier Cover suits any Ergobaby carrier in all carry positions. Match the accessory to how you actually move before adding a second cover.
Product Facts at a Glance
- Metro 3 Weather Shield: Protects little ones from rain, wind and snow, with advanced ventilation for airflow, coverage in all seating positions, and it fits into the Metro 3 storage basket. You get full-seat coverage without trapping heat, and the shield stays with the stroller instead of being left at home. Note that Ergobaby says it should not be used when a car seat is docked onto the stroller.
- Metro 3 Carry Bag: Keeps your Metro 3 clean and scuff free during travels and storage, with padded backpack-style straps, wipeable fabric, and it rolls up small to fit in the stroller's storage basket. The padded straps make a folded stroller genuinely carryable through airports and parking lots, and the wipeable fabric means grime comes off instead of settling in.
- Metro 3 Footmuff: Water-repellent exterior and premium fleece interior, an easy-to-clean internal wipeable panel, folds with the stroller, suits children 6 months to 4 years old, and is machine washable. For cold-weather walks, one footmuff covers warmth and light weather protection, which can replace the Weather Shield for older babies and toddlers.
- Rain and Wind Carrier Cover: Water-resistant and lightweight, compatible with any Ergobaby carrier in all carry positions, quick and easy to attach and remove, and stores compactly in a detachable pouch. If you wear your baby more than you push, this is the weather layer that matches your routine rather than a stroller accessory.
Which One Should You Buy?
Best for
- Parents who walk in rain, wind, or snow with a child seated in the Metro 3
- Families who want a cover that stays in the stroller basket and works in every seating position
- Travelers who fold and store the Metro 3 often and want it to arrive scuff-free
- Carry-heavy parents who need weather protection for an Ergobaby carrier instead
Not for
- Parents using the Metro 3 with an infant car seat docked, since the Weather Shield should not be used in that setup
- Anyone expecting a carry bag to keep a child dry or warm
- Warm-climate families who never encounter rain, wind, or snow
- Parents who want one purchase to cover both warmth and stroller protection
Start with the accessory that matches your biggest recurring annoyance: wet weather or a dirty folded stroller. If both apply, the Weather Shield and Carry Bag are small enough to keep in the Metro 3 basket together, and the Footmuff or Rain and Wind Carrier Cover can cover the seasons and carrying styles in between.
