## Long description

The Hydro Flask HF-Butelka 21oz (Standard Mouth) with FlexStraw Cap in Agave is an insulated stainless-steel water bottle designed to maintain beverage temperature while providing convenient access through a straw-style spout. With a 21-ounce (approximately 621 ml) capacity and vacuum-insulated construction, this bottle is engineered for everyday hydration, commuting, travel and outdoor use. The standard mouth provides a balance between ease of filling and compatibility with ice, while the FlexStraw cap offers simple, spill-reducing sipping without tipping the bottle.
Advantages
Vacuum insulation helps preserve cold drinks for extended periods and reduces heat transfer from warm beverages. The stainless-steel body is durable and resists odors and stains. The FlexStraw cap provides a built-in straw for one-handed drinking and includes a flexible hinge that allows the straw to fold down for transport. The bottle’s size and weight are intended to be portable for day-to-day use and outdoor activities.
Suitable for
Daily hydration at work, school or home
Commuting and public transport
Light outdoor activities such as hiking, cycling and picnics
Travel and flights where a spill-resistant drinking option is preferred
Key specifications
Capacity: 21 ounces (approximately 621 ml)
Material: Double-wall stainless steel with vacuum insulation
Mouth type: Standard mouth compatible with ice cubes
Cap type: FlexStraw cap with straw-style spout and folding hinge
Finish: Powder-coated exterior in Agave color for improved grip

How to use
Fill the bottle through the standard mouth and secure the FlexStraw cap by aligning and pressing until it locks. To drink, flip or pull the straw spout into position and sip through the straw; fold the straw down and close the cap when not in use. For best thermal performance, pre-chill or pre-warm the bottle briefly before adding your beverage. Avoid placing the bottle in a microwave; follow manufacturer cleaning guidance for the cap and bottle components.
Usage recommendations
Hand wash the FlexStraw cap and bottle components when possible; if dishwasher-safe parts are indicated by the manufacturer, place them on the top rack. Regularly clean the straw and drinking spout to prevent residue buildup. Use with cold or room-temperature drinks for optimal insulation performance and avoid filling with carbonated beverages to prevent pressure buildup.
