This beanie will help keep you super warm! My head actually started sweating. Great for days of freezing temps!
First, the hat. It is SO WARM! It is almost like there is an extra layer of insulation just where I need it - around my ears. SUCH A GREAT DESIGN! It is warm and cozy, and SO SOFT! I love the print and wish they came in more colors. Next, let's talk about the delivery time. I think Alter Ego Running may just be giving Amazon a run for their money. I had this hat in TWO DAYS! And I so appreciated the customer service - emails with updates about where my hat was. Such a nice touch! After this purchase, I will be making more from you. LOVE supporting small, local businesses. One tip - I know you are in Florida, but us northerners would appreciate more winter beanies to enjoy! ;-) Thanks!
Extremely comfortable and warm! Great for super cold runs.
This is, hands down, the BEST beanie I have ever owned. Not only is it adorable, but it is soft and comfortable too. The inside fleece lining is the perfect touch. This beanie sits perfectly on your head, with the cute pom on top, and it’s not itchy at all.
I hope there are many new colors and designs in the future.
Do yourself a favor and add one of these to your cart!
