Short answer: yes — but check your lower adapters first, not your model year. The YETI Hopper Flip Cooler Mount for UPPAbaby Vista ships today, in Hopper Flip 8 and Hopper Flip 12. It fits the original pre-2024 UPPAbaby lower adapters. It does not fit the 2024 lower adapters — UPPAbaby part 0901-VLA-NA, the ones included with a RumbleSeat V2+ or V3. A version for those is in development. Vista frames from 2014 and earlier use a different mounting interface and are not compatible at all.
Which lower adapters do you have?
This is the question that decides it, and the model year of your stroller does not answer it — both sets of adapters fit the same Vista frames. UPPAbaby redesigned the lower adapters in 2024 so one set could carry the bassinet, the car seat and the new RumbleSeat, and the redesigned adapter has a different receiver.
The quickest test: does your RumbleSeat clip into the same lower adapters as your bassinet?
• Yes — one set takes the bassinet, the car seat and the RumbleSeat. Those are the 2024 adapters. The mount that ships today will not fit them.
• No — your RumbleSeat came with its own separate adapters, and the lower adapters only take the bassinet or an infant car seat. Those are the original adapters, and the mount that ships today is the one you want.
If you do not own a RumbleSeat, go by where the adapters came from: bought in 2024 or later, or found in the box with a RumbleSeat V2+ or V3, they are the new ones; bought before 2024 as a separate accessory, they are the original ones.
UPPAbaby describes the 2024 adapters as having larger hubs than the ones they replaced, and sells them as fitting the Bassinet, Aria, Mesa V2 and Mesa Max and the RumbleSeat V2+ and V3. The original adapters were never sold as fitting any RumbleSeat.
Still not sure? Send a photo of your lower adapters to Support@StrollerHouse.com before you order and we will tell you which one you need.
We originally listed the Vista mount as fitting every Vista from 2015 onward. That was wrong, and a customer found it before we did. Both listings now say exactly which adapters they fit.
The Gazelle S version
If you are on a Gazelle S or eGazelle S, the YETI Hopper Flip Cooler Mount carries a Hopper Flip 8 or Flip 12 down in the lower slot. One mount, and you pick the size. The Gazelle S uses the frame's own lower slot, so there is no adapter question on that frame.
How the Vista mount works
It mounts in the lower position only — there is no upper version and there will not be one — and it ships as a matched pair of mounts, printed in black PETG, made to order. The Vista lower position holds one thing at a time, so it is the cooler mount or a lower-slot adapter down there, never both. Everything above is unaffected: toddler seat, bassinet and infant car seat all mount as usual, and the seat still reclines fully.
Why a cooler always mounts low
A loaded Hopper Flip is heavy, and hanging weight is the single most common way a stroller tips — which is why every stroller manual warns against hanging bags from the handlebar.
So the mount puts the cooler in the lower position, inside the wheelbase, where the weight is carried rather than levered. There is no handlebar version and there will not be one. That constraint is the entire reason it is safe to hang a cooler off a stroller at all.
What it carries — and what it never carries
The mount carries the cooler and its contents. It never carries a person's weight: no child sitting, standing, leaning or climbing on it. It is not a step and it is not a seat, and nothing other than the cooler hangs from it.
Which sizes
Hopper Flip 8 and Hopper Flip 12. These are different mounts, not one adjustable part, so check which cooler you own before ordering. The Hopper Flip 18 is not currently supported.
One slot, one accessory
On the Gazelle S the lower slot is single-occupancy — it is the cooler or the shopping basket, never both. Everything above is unaffected: toddler seat, carrycot and infant car seat all still work.

• A CYBEX carry cot on an UPPAbaby Vista.
• Balance Bike & Scooter Holder for the Vista — ships now. A pair of cradles on the upper side frame tube, either side, so a balance bike or a kick scooter rides home instead of being carried. This one clips to the frame tube, so the lower adapter question does not apply to it.
