Stainless Steel and Glass Tumbler by gsi outdoors, Glacier 236 ml (8 fl. oz.), Mineral Yellow

The gsi outdoors Glacier stainless steel and glass tumbler, 236 ml (8 fl. oz.), Mineral Yellow, pairs a durable stainless-steel outer shell with a removable inner glass cup to offer beverage purity and improved break resistance for outdoor use. Designed for camping, picnics and travel, this compact tumbler provides a clean-tasting surface for hot or cold drinks while the outer stainless body adds protection and easier handling. The combination of materials preserves flavor, reduces metallic aftertaste and allows simple cleaning after use.

Advantages

The stainless-steel exterior increases impact resistance and thermal insulation compared with a bare glass cup, while the inner glass liner maintains the neutral taste and chemical inertness of glass. Its 236 ml capacity is convenient for single servings of coffee, tea or cold drinks. The Mineral Yellow finish improves visibility in outdoor gear and the compact form factor fits standard picnic and camping storage. The construction is intended to balance robustness with beverage purity for routine outdoor dining needs.

Suitable for

• Camping and backpacking where a balance of durability and taste is required
• Picnics, beach outings and day trips
• Travel and car trips when a compact, refillable cup is preferred
• Outdoor dining and campsite beverage service

How to use

Use the tumbler by placing the glass liner inside the stainless-steel shell and filling to the desired level, observing the 236 ml capacity limit to avoid spills. It is suitable for both hot and cold beverages; allow hot liquids to settle briefly before drinking to verify the temperature. After use, separate the glass liner from the stainless shell for cleaning and dry both parts thoroughly before reassembly and storage.

Usage recommendations

For best results, hand wash the glass liner with a non-abrasive detergent and allow it to air dry. Avoid subjecting the exterior or interior to strong impacts; while the stainless shell improves resistance, the glass liner may still break if dropped from height. Do not use with carbonated beverages if a tight seal is required; pour slowly to avoid overflow. Store disassembled to ensure thorough drying and prevent trapped moisture.
