such a lovely beanie!

(This review was collected as part of a promotion.) Very light for in-between season and it covers the ears!

Does not fit a smaller head

Great pattern, well constructed, but does not have enough stretch/elasticity to make it truly one size fits all. I have not had an issue with previous IB winter hats & beanies that I have purchased, but this one was fair too big/loss. Am both saddened and disappointed as I was very much looking forward to this being my new go to winter hat.

Great Beanie Hat

The ear flaps are a cold weather game changer for all outdoor winter activities. Especially appropriate under a ski or bike helmet

Great Fit, Excelent weight for athletic endeavours

(This review was collected as part of a promotion.) I have used this toque for active winter adventures. It is a great weight for active pursuits. XC skiing and walking the dog. Fits well on my large melon. Very comfortable. Breathes well.
