What Our Gearhead(R) Experts Are Saying:"I keep a MagSlider Pack on my desk at home, and honestly, the best part is never arguing about whose cup is whose at the trailhead anymore. They pop on and off in a second, go through the dishwasher without a second thought, and it's a genuinely satisfying little upgrade to drinkware you already love."The details are what make something yours. The YETI MagSlider Pack is a simple three-pack of colored magnetic lid inserts that snap onto any Rambler Tumbler or Mug with a MagSlider Lid, swapping out in a single move whenever the mood calls for it. It is the kind of small addition that quietly improves the daily routine, whether that means telling your cup apart from everyone else's at the office, matching the season, or just adding a little personality to something you reach for a dozen times a day. The magnets pop on and pop off cleanly, go through the dishwasher without complaint, and stay put in the lid when it matters. Three colors per pack means options without overthinking it.
