Zephyr Canyon 20 oz Mason Jar Tumblers — 4-Pack Clear Double-Insulated with Handles & Lids

These clear, BPA-free acrylic mason jar mugs combine the nostalgic jar silhouette with modern double-wall insulation and practical features for everyday use. Each 20-ounce jar arrives with a color-matched screw lid and a reusable straw, plus a sturdy built-in handle for easy carrying. The wide mouth makes filling and cleaning straightforward, and the spill-resistant lid helps reduce accidents around kids, desks, or picnic blankets.

How well do these tumblers keep drinks hot or cold?

The double-insulated construction slows temperature transfer, helping beverages stay nearer to their original temperature longer than a single-wall plastic cup. While not vacuum-sealed like stainless tumblers, the dual-wall design reduces condensation on cold drinks and helps maintain warmth for short periods.

• 20 ounce capacity for standard iced or hot servings
• Double-insulated acrylic reduces heat/cold transfer
• Wide mouth allows easy ice insertion and pouring
• Not a vacuum flask—best for several hours, not all-day thermal retention

Are these safe and easy to clean?

The jars are molded from BPA-free acrylic, a food-safe plastic that avoids the taste issues of some materials. Handwashing is recommended to preserve the lid finish and the straw seal; the wide mouth simplifies rinsing and accessing all interior surfaces.

• BPA-free acrylic body for food-safe use
• Screw-on lids and removable straws for thorough rinsing
• Handwash recommended to extend lifespan
• Not recommended for microwave or high-temperature dishwasher cycles
