I have a Klim that the velcro collar/strap can tuck into itself (if that makes sense). I can ride with it unzipped say 6 inches and not worry about the strap sand blasting away at my neck.
the simplest answer is always right in front of usI have to say.. none of my jackets do this. I recommend neck lengthening exercises.
I just looked in my closet. I was wrong. It is my Alpinestars jacket that has a "loop" you can double back the velcro flap into. My Klim has a fabric "tent" over the top of the zipper to avoid neck irritation. It's a mesh Induction jacket.Which model Klim do you have? Their offerings kind of run the spectrum.
I've got the neotec II and even with the ratchet buckle, it catches on my collar flap when I rotate my head back to center after looking hard right. I need to go try on some jackets while wearing my helmet to see what's different about the other suggested brands (I would trade my kingdom to be closer to Iron Pony).My new Shoie Neotec has a different buckle and it seems like that is helping. It's the std loop buckle that always got caught.
