Insulated Jar Hydro Flask 20 oz Black - Hydro Flask RF20001

The Hydro Flask Jar 20 oz in black is an insulated stainless steel food jar designed to maintain the temperature of soups, stews, beverages and prepared meals. With double-wall vacuum insulation and a compact 20 oz (approximately 591 ml) capacity, this jar provides portable temperature retention for work, travel and outdoor activities while its durable exterior resists everyday wear.

Advantages

The jar uses TempShield double-wall vacuum insulation to keep contents hot or cold for extended periods and a stainless steel interior that resists flavor transfer and staining. A leak-resistant lid and a wide mouth make filling, eating and cleaning straightforward. Its compact shape is suitable for backpacks and lunch bags, and the powder-coated finish improves grip and scratch resistance.

Suitable for

• Carrying hot soups, stews or porridges for work or school
• Transporting chilled salads, yogurts or cold beverages
• Day hikes, commuting and travel where insulated food storage is needed
• Meal prep and portioned food storage for single servings

When it may not be suitable

This jar is intended for single-serving food and beverage storage; it may be too small for sharing or for large family portions. It is not designed for long-term storage of perishable food beyond recommended refrigeration and should not be used in microwave ovens.

How to use

Preheat or precool the jar by filling it with hot or cold water for a few minutes, then discard the water before adding your food or beverage to improve temperature retention. Secure the lid by screwing it on until it is snug and transport the jar upright to minimize risk of leakage. Clean the jar after each use by hand washing the lid and jar with warm, soapy water and allowing both parts to air dry; avoid using abrasive cleaners that can damage the powder coat. Do not place the jar in the microwave; the stainless steel construction also makes it unsuitable for microwave use.

What to consider before purchase

• Capacity fits single servings; check volume against your typical portion size
• Stainless steel construction is durable but not microwave-safe
• Powder-coated finish improves grip but may show wear over time with heavy abrasion
• Leak-resistant lid reduces spills but transporting upright is recommended

Usage recommendations

For best results, preheat or precool the jar before filling, store upright during transport, and hand wash regularly. Use the jar for single-serving meals and beverages to make the most of its insulation and portability.
