The single Mountain Buggy Nano was one of the first “tri-fold” strollers to ever hit the market. “Tri-folds” are the smallest and most compact of the lightweight strollers; they are also the lightest in weight, so we are super excited about this Mountain Buggy Nano Duo Stroller Review.
We dubbed the single Nano the “tiny workhorse” of strollers, so we were ecstatic to hear of a double version of this lightweight wonder. We’ve never seen one before… could it be done??
If you have twins or small children closer in age, this lightweight, compact side-by-side double stroller may be just what you need. While the Mountain Buggy Nano Duo certainly isn’t your all-terrain or heavy-duty double jogger, it is ideal for travel and everyday car errands.
As you may know, double strollers are typically HUGE monstrosities, not to mention extremely heavy (usually 25-40 lbs). The lightweightedness of this stroller makes it super easy to transport, a special plus for city dwellers who need to throw their double stroller in the back of taxis or Ubers, or carry them up sets of stairs. Bonus: it accepts two infant car seats, and is compatible with Mountain Buggy’s awesome new Cocoon for Twins.
Size & Weight
The Mountain Buggy Nano Duo weighs in at just 20 lbs (yes — you read that right: a double stroller that weighs only 20 lbs!) and can hold up to 33 lbs per seat. As stroller seats go, that’s not a ton of weight — depending on the weight of your children, it may only get you to their 3rd birthdays… but since it’s newborn compatible (more on that later), it’s a good “early days with twins” (or two close in age) stroller solution.
Aesthetic-wise, while the frame and seat of the Nano Duo are all black, you can add a fun pop of color by choosing from 5 different canopy colors: Cyber (yellow), Silver, Ruby, Nautical Blue and Black. (OK – so black won’t give you the color pop… but the others?! Ohh la la! Pretty!).
Something to note is that at ~ $549, the Nano Duo is definitely pricier than many of the other double umbrella strollers — i.e. the Maclaren Twin Triumph (~ $350), UPPAbaby G Link2 (~ $350), Joovy Twin Groove Ultralight (~ $250) and the Zoe Twin+ (~ $329). The Zoe Twin+ is a (somewhat) comparable stroller, but it folds in half rather than in thirds, making the folded size of the Nano Duo more desirable. Thus, you are really paying a premium for the uber-compact fold.
Plus, you are getting slightly better features than on a double umbrella stroller, which are usually pretty bare bones when it comes to storage, push, etc.
Car Seat Compatibility/Newborn Cocoon
One of our favorite features for twin parents: the Mountain Buggy Nano Duo can accept two infant car seats, when paired with the Nano Duo Twin Car Seat Adapter. The adapter is compatible with the following car seats: Mountain Buggy protect infant car seat, phil&teds alpha, Maxi-Cosi Mico, Peg Perego Primo Viaggio, Cybex Aton, Aton 2, Aton Q, Nuna Pipa, Graco Snugride 35, Snugride Click Connect 35 and Chicco Keyfit.
Alternatively, the seats lay flat, and if you have twins, Mountain Buggy has recently come out with a cocoon for newborn twins (~ $99)! This is essentially like a soft-sided double bassinet (see below).
Mountain Buggy has always been known for a cool accessory they call the “Cocoon.” With one or two (for twins) of these puppies, your babe(s) can lie snugly together in their cocoons, which clip right onto the stroller without the need for additional adapters.
The Cocoon is suitable from birth through 6 months of age, and may also be used off the stroller for naps or nighttime sleep. Meg used the Cocoon with Alice and loved that she could lift her off the stroller and carry her anywhere, even while napping. Like a sweet little package ❤️.
Plus, the Cocoon has a sunshade to protect your littles from the rays. Seriously, though — how cute is this thing?! Wishing my twins were infants again so I could put them in here…
The seats on the Nano Duo are each 16” in height, recline independently, are equipped with a 5-point safety harness and have their own adjustable footrest. That is all to say: though small, they are full-featured seats.
As previously mentioned, they can only hold children up to 33 lbs — again, with that low weight limit, you need to know that this stroller isn’t going to last you through your kids’ entire childhoods. To be frank, this is more of a “little kid” stroller and will not be one you can use with bigger, older preschoolers, like some of the sturdier double umbrellas or all-terrain double strollers. Bummer for sure.
In contrast, the Zoe Twin+ stroller, which is also a fab travel stroller and has a similar weight as the Nano Duo at 19 lbs, can hold kids up to 45 lbs per seat, the Maclaren Twin Triumph can hold up to 50 lbs per seat, and the UPPAbaby G Link2 can hold up to 55 lbs per seat. These are big differences for sure; due to their higher weight limits, all of these comparable strollers will last you longer than the Nano Duo.
That said, none of these double strollers offer newborn solutions (i.e. they don’t accept car seats, nor do the seats lay completely flat), so with the Nano Duo, you can at least start using it right away.
Canopy, Basket, Handlebar, Brake
The Nano Duo offers fair sun coverage, with two independently-operated three-panel canopies. I wish these canopies were a little bigger, but they are certainly not bad. They also don’t have peek-a-boo windows for checking on your kiddos, which is a shame (I LOOOOOVE peek-a-boo windows). In comparison, the Zoe Twin+ offers large, 4-panel canopies with UPF protection and peek-a-boo windows with magnetic closures.
The underseat storage basket is really ample, and can hold approximately 17 lbs of… stuff (and us moms of multiples can definitely fill a storage basket with that much stuff!). That said, some think the basket is hard to access due to the stroller frame’s bars that are in the way — see picture below. Again, this is a convenience stroller – you aren’t going to find the giant baskets you’ll find on larger strollers.
Unfortunately, the handlebar on the Nano Duo isn’t adjustable. This isn’t a dealbreaker, just something to know… especially if you’re tall. It might not be great for super tall caregivers, as they may wind up kicking the rear axle while pushing this stroller.
The Nano Duo has a single action color-coded brake on one set of the rear wheels that’s simple to engage (and summer-shoe friendly to boot). Step back on the red lever to engage the break, and forward on the blue lever to release it. Easy.
Here’s the deal: like all (most?) travel strollers, the Nano Duo performs best on even, flat terrain. It’s really best for those who plan to use it on paved sidewalks, strolling through a mall, walking through the airport, etc; it most definitely does not perform well going over uneven terrain such as gravel, cobblestones, bumpy roads or grass.
That said, those who use the Nano Duo on even surfaces say it maneuvers and rides quite well. The Nano Duo is equipped with 5” EVA wheels (these wheels are not air-filled, which is why they don’t handle well on bumpy terrain, but the upside is that they’ll never go flat), rear wheel suspension for a smoother ride for your littles, and the ability to swivel or lock the front wheel for better maneuverability and stability.
The fold — along with its compact size once folded — is where this stroller really shines. The Nano Duo has a two-step, “Z-shaped” tri-fold (you’ll see what I mean in the video below… ), which sounds annoying at first, but hear me out: once you get the hang of it, it’s a cinch, and it becomes so small you can easily throw it in your trunk, or carry it over your shoulder with the attached shoulder strap.
To fold the Nano Duo, first make sure the canopies are all the way back. Then press the two buttons on each side of the inner part of the stroller, which will fold the top part of the stroller and canopies backwards. Then push that part forward to fold the other way, and the stroller will collapse and lock into place.
It can self-stand once folded, or you can grab the shoulder strap and carry it like a bag.
For a visual out of how to fold this stroller (seriously, it will make so much more sense once you SEE IT), go to 1:17 of this instructional Nano Duo video.
In addition to the car seat adapter and Newborn Cocoon (which you can purchase as either a single or double) mentioned previously, you can also buy a grab bar, rain or sun cover, extra storage/parent organizer or a travel bag to go with your Nano Duo.
At 20 lbs, the Mountain Buggy Nano Duo is one of the lightest double strollers on the market. With its super compact fold and carry strap, the Nano Duo is a great choice for those who live in a city or somewhere with flat terrain, and for families who like to travel.
It’s awesome for infant twins, because unlike other double travel or umbrella strollers, it can accept two infant car seats, or babies up to 6 months can snuggle together in the Mountain Buggy Cocoon for Twins (for families with two kiddos close in age, the Nano Duo can also accept just one car seat, or a single Cocoon made for one infant).
Before purchasing, however, keep in mind that the weight limit is only 33 lbs per seat — meaning the Nano Duo is only meant to last until your kids’ 3rd birthdays. Another downside is that while the underseat basket is large, it’s difficult to access due to the bars around it. In addition, the Nano Duo doesn’t have an adjustable handlebar, so if you’re a tall parent you may want to look elsewhere.
But overall, if you have newborn twins, or two small kids (under three) close in age, and are looking for an everyday stroller that’s easy to throw in the car, store in your garage or home, run errands with or take on trips, the Mountain Buggy Nano Duo may just be the perfect fit for your family.
