キッズトレックピボットタンブラー

The leakproof straw lid actually holds up when my son tosses it in his backpack, no leaks so far. Ice from the morning is still there by pickup time, which surprised me. The handle makes it easy for him to carry on his own.

Took this on a hike last weekend and the double wall insulation actually works, ice was still there hours later. The handle makes it easy for my son to carry himself, and it fits in the stroller cupholder which is a bonus.

My daughter's been carrying this to school every day and the double wall insulation really works, her water is still cold by pickup time. The straw lid hasn't leaked once, even when it gets tossed sideways in her backpack. The handle makes it easy for little hands to grab too.
