40oz Multi-Function Vacuum Dismountable Tumbler

**40oz Dual-Chamber Stainless Steel Tumbler | Leak-Proof, Handle & Straw | Vacuum-Insulated Travel Mug Keeps Drinks Cold 34 hrs / Hot 12 hrs | Cup-Holder Friendly | Dishwasher-Safe, BPA-Free**

1. **2-in-1 Detachable Design – Hydration & Coffee in One Hand**  
Split 40 oz into two 20 oz chambers. Carry ice water AND hot coffee at the same time without mixing temperatures or flavors. Twist apart to share, refill, or throw one half in your gym bag while the other stays at your desk.

2. **All-Day Temperature Lock**  
Double-wall copper-plated vacuum insulation keeps beverages icy for up to 34 hours, steam-hot for 12 hours. No condensation, no lukewarm sips—tested to outperform Yeti & Hydro Flask in 3rd-party labs.

3. **Truly Leak-Proof, Shake-Proof, Backpack-Safe**  
Each chamber has an independent silicone-sealed flip lid; the center joint uses a food-grade gasket rated for 1,000+ twists. Toss it sideways in the car seat or sprint for the train—zero spills, zero stains.

4. **Built for Big Thirst & Small Cup-Holders**  
Slim 3.1" base fits standard car, stroller, and Peloton cup holders, yet still delivers a full 40 oz capacity. Ergonomic 360° rotating handle folds flat for packing and locks upright for one-finger carry.

5. **Health-First, Dishwasher-Safe Materials**  
18/8 kitchen-grade stainless steel, BPA-free Tritan lids, and metal straws. Powder-coat finish won’t chip or peel. Entire tumbler is top-rack dishwasher safe—no brush required.

6. **Gift-Ready & Planet-Friendly**  
Plastic-free packaging, reusable straw brush, and color-matched tote bag included. Perfect for commuters, campers, students, and new moms. Backed by a lifetime warranty and 24-hour US-based customer support.
