The Mountain Buggy Nano Duo earned our Editors' Choice award, beating out most of the contenders in our double umbrella stroller review. It outshines the competition as one of the smallest options when folded, making it a prime candidate for parents with smaller vehicles. This stroller has a high storage weight limit, self-stands when folded, and has limited flex in the frame, which is a rare feat for an umbrella style stroller. Unfortunately, the Nano Duo has small canopies with no peek-a-boo windows, and it lacks additional features like cup holders or other storage pockets. It also sports a higher price than most of the competition. However, we think it is a quality stroller with stylish features that many parents will love, with a size and weight that even more will appreciate.

Our Analysis and Test Results
In 1992, a dad was inspired to start Mountain Buggy when he couldn't find a great all-terrain option for exploring the backwoods of New Zealand. With a clear goal, he created the Moutain Buggy's all-terrain platform and launched his first stroller. The company continues to improve its designs, creating products for newborns to toddlers for city life and mountain trails.
Weight and Folded Size
The Nano is one of the smallest folded strollers in the group at 7,484 cubic inches, helping it earn an eye-catching high score in this metric. It weighs 20.3 lbs, which is relatively lightweight for the group. These measurements make the Nano a good choice if your space is limited or you have difficulty lifting heavier things.
Ease of Use
The Nano isn't as easy to use in comparison to some of the competition, earning it a mediocre score in this metric. However, only a handful of strollers scored higher as much of the group lacks features parents will be looking for.
Fold and Unfold
Folding the Nano is somewhat complicated to fold with an automatic lock (above left) and self-stand. It requires two hands to fold and unfold. You need to really compress the stroller to engage the lock, and you need to secure the wrist strap to prevent the handlebar form unfolding on its own. It has a carry strap for easier carrying (above right).
The Nano has single action brakes with a color-coded pedal (above left) that is easy to operate. The brakes are press to set and release (above right), making them foot-friendly no matter your footwear.
The Nano storage bin is medium in size and holds our large diaper bag. It has a large maximum weight limit of over 17 lbs, but the bars make it difficult to fit larger bags inside. There is no other storage on the stroller.
While the sunshades on the Nano are not particularly large and did not necessarily impress, they do offer more coverage than some lightweight double strollers.
However, it is easy to operate and has a flip-out visor. It does not have a peek-a-boo window, and it doesn't rotate forward to offer protection from wind or low setting sun.
The Nano harnesses are 5-point and have shoulder padding. The harness is easy to adjust and can be made small enough for petite passengers. The buckle works well, but you have to put in each strap on its own, so it is involved and takes extra time. The crotch strap is not adjustable.
The Nano seatbacks do not recline very far, and heads will be lolling during nap time. The seatback adjustment toggle (above left) is easy to use and has infinite angles within the range. The adjustable leg rests (above right) are padded, but they have a bar right at the bend in the edge of the seat that could cause some discomfort on longer rides.
Ease of Setup
The Nano Duo is easy enough to set up with a time of about 3 minutes and 30 seconds, and no tools are required. The manual is average, but at least it isn't confusing.
The Nano earned a below-average score for maneuverability, despite having the higher-performing single front wheeled design. This score is one of the highest in a group that generally disappointed when it came to ease of pushing or turning.
The front swivel wheels can lock into place for easier pushing over uneven terrain; however, it really only moves well over flat surfaces.
The front wheels are narrow set, and we didn't have any difficulty getting them through our testing course or doorways. The wheels are foam filled plastic and smaller than we'd like for best maneuverability.
The Nano Duo is a nicer quality stroller than most umbrella options, earning it a relatively high score in this metric. The stroller frame has better than average flex, and the fabric fits the frame nicely. The connection points are solid, and the overall fit and finish are simple but well-executed. The Duo has canvas fabric that feels durable but not as comfortable as we'd like.
