Yes, the other NS member who commented about us changing the zippers on the sleeves on the new gear is correct. They now have a locking zipper puller to keep the sleeves from unzipping on their own.
We haven't had any problems with the zippers breaking, but if you had some teeth break off, then definitely hit us up- that is something that is covered under warranty. Shoot us an email to info@fdwear.com with some pics and we'll get that taken care of for you!
