Siply Leak-Proof

Leak-proof when open. Leak-proof when closed. Just right all the time. Every spout in this collection uses patent pending valve technology, so drinks stay put in backpacks, cupholders, and car seats. Choose your size and material, from lightweight plastic to vacuum-insulated stainless steel that keeps water cold for hours. Then pick your look from bold, playful designs made for kids and grown-ups (coming soon!) alike. Carry handles, cupholder-friendly shapes, and easy-clean pieces come standard. At zak! designs, we're keepin' it Siply.
