Excellent neck tube not to tight and plenty of air vents in it to breathe.

Perfect neck tube not to tight and the breathable mesh is excellent, a big strip of breathable mesh down one side and if you're feeling the cold turn it round and their is a smaller breathable mesh bit that just covers your nose and mouth. I just wish you had more colours especially something like a bright orange for people who maybe skiing or hiking and need to be seen or stand out. I have tried many necktubes and most are either to tight or go bobbly within weeks but so far this is holding up fine. Give these a try folks!
