Sure, the lids on Yeti's Rambler Tumblers are shatter resistant and dishwasher safe. But you still might need a replacement lid if you happen to misplace yours while in the field or accidentally drop it down a volcano. Don't worry: just like your original Rambler Tumbler lid, these replacement lids are splash resistant, easy to clean and completely clear so that you can assess your refill needs at a glance. Dishwasher safe.
