I just wanted to personally thank you for helping me with the ordering of a coat I purchased on Monday. It arrived at 10 am this morning and is perfect. It was a gift for my boyfriend and I?m sure he is going to love it. Up North Sports has the best customer service of any company I have ordered through and we will both be using you for all of our winter wear needs. Again thank you for the remarkable service and I have been and will continue to recommend your business to people.

Ask a Product Question
(Answers) Is L or M cloer to the M/L model I bought in 2022
I had a 509 altitude helmet 2.0 (think it was a 2022 or 2023 model) that was M/L that fit better than the large. I recently had an accident and need to replace my helmet. Will the medium or L be closer to the M/L size that I had previously.
