Hi, I had the Bugaboo Bee + and used to different Footmufs: the Bugaboo Bee * one and a lined Red Castle. The red castle was amazingly cozy and fitted really well in the Bugaboo bee. When he became over a year I changed to the bugaboo foot muff which is much larger but less warm. I sold my Bugaboo bee stroller last week and bought a Babyzen Yoyo for mi one, as I needed it for traveling. I am not using the footmuffs anymore so I putted them up for sale.
