## Description

Meet the Simple Modern Summit Kids Water Bottle - the 14oz and 18oz insulated stainless steel bottle we designed for the toddler-through-elementary years, when life happens at preschool-pickup speed and every sippy cup, kids cup, and water bottle ends up in a diaper bag, car seat, or backpack. We made it for moms like us. You already have enough to carry without worrying about whether a kids water bottle is going to leak onto a library book. The straw lid stays spill proof when the nozzle is closed, so you can toss it in a backpack for school drop-off, stash it in a stroller, or hand it to a 3-year-old in the back seat and not think twice. Double wall vacuum insulation keeps water and juice cold for hours - from the morning carpool through afternoon pickup. The food-grade 304 (18/8) stainless steel interior is made to last, and our Summit kids tumbler is made without BPA, lead, or phthalates, so you can trust it from the toddler cup years on up. Recommended for children ages 2 and up, both sizes fit comfortably in toddler and preschool hands, slide into most car and stroller cupholders, and tuck neatly into lunchboxes and backpacks. At the end of the day, the lid and bottle are top-rack dishwasher safe - one less thing to hand-wash before bedtime. A practical, thoughtful pick for birthdays, back-to-school, holiday gifts, and stocking stuffers - especially for the toddler girls, toddler boys, and the 3-, 4-, and 5-year-olds in your life who want a grown-up water bottle of their own. Most bottles pair with a matching Simple Modern Hadley kids lunch box and Fletcher backpack, so they can feel confident and stylish at school. Every Simple Modern product is thoughtfully designed for the way families really live - with care put into the everyday details and on-trend style for the whole family. So you can feel good about your purchase and maximize what your family's budget can do. Not for hot or carbonated beverages. Pat/Pat Pending.

## Questions & Answers

**Q: It's the spout hard plastic or silicone?**
A: Spout is hard plastic

**Q: Can I put some water in the bottom and freeze it for a long lasting ice cube?**
A: I wouldn't - 1) it would impact the straw fitting in and working and 2) If the top of the water freezes before it is solid it could warp the metal interior. A The opening is wide enough to accommodate large sized cubes anyway so i really don't see a need. We put in a handful of ice maker crescent shaped cubes and it last all day.

**Q: Does it keep liquid warm?**
A: I’m not sure we’ve only used them for cold liquids. But work great for cold milk and iced water.

**Q: Is there a way to buy extra straws for this? Somehow I lost the straw when I detached it to clean it**
A: Yep! You can for sure do it on the Simple Modern website. Not sure if Amazon sells them as well.
