Comfort features for baby

Large, individual 600D canopies with a UPF 50+ rating and flip out sun visors, protect your babies as you stroll, and a peek-a-boo flap quietly allows you to keep an eye on them from above. The duet stroller's wipe clean polyester fabric is super lightweight, water repellent and durable, and zips easily off the frame.

Padded, tail-free harnesses keep your babies secure in their seat and are easily adjusted as they grow. The seat positions transition from a full recline for newborns to upright for an older child, and a convenient ‘gate’ opening bumper bar allows you to easily get your babies in and out of the stroller.

mountain buggy duet


The buggy was great initially handles really well and the width is great but my twins are only 7 months old and we've had to buy new tyres and inner tubes for 3 of the wheels. The tyres have completely split and fallen apart and of course they're not covered by the warranty.
