20oz Black Insulated Tumbler 12 Pack - Double Wall Stainless Cups

Our review of the HASLE OUTFITTERS 20oz tumbler 12 pack finds these cups aimed at people who want a reliable, everyday insulated mug for travel, office, or events. The single biggest reason to buy this set is consistent, durable insulation in a compact 20oz size that fits most car cup holders and stays comfortable to hold thanks to a powder coated finish. For anyone who needs multiple matching tumblers for a household, office, or group activity, this 12 pack delivers uniform quality without fuss.

Key Features

• Insulated Double Wall: Vacuum insulated dual walls keep drinks icy cold or piping hot for hours for steady temperature control on the go.
• Premium Material: Constructed from 304 food grade stainless steel with an electro polished interior to resist rust and remain unbreakable for long term use.
• Colored Powder Coat: The powder coated exterior improves grip and resists fingerprints while providing a matte finish that feels comfortable in hand.
• BPA Free Lid: The AS lid includes a removable rubber gasket and a wide mouth opening for easy filling and cleaning while remaining straw friendly.
• Fits Most Cup Holders: The 20oz size is lightweight and compact, designed to slide into standard car cup holders for commuting and travel.
• Pack Quantity: Twelve identical tumblers provide value and consistency when you need matching cups for groups or repeat use.

Who It's For

This 12 pack is best for families, small offices, event hosts, or anyone who prefers buying multiple identical insulated tumblers to keep beverages at the desired temperature across many users. The durable 304 stainless construction and powder coat finish make them suitable for regular daily use, outdoor picnics, and light travel.

Those who want a single premium showpiece tumbler, a slender or oversized travel mug, or a model with advanced spillproof mechanisms might look elsewhere; these offer a simple, straw-friendly lid rather than a full locking drinking system.

Frequently Asked Questions

Are these tumblers dishwasher safe?
Hand washing is recommended to preserve the powder coat finish and gasket; the interior stainless surface is durable but lids and gaskets may wear faster in a dishwasher.

Do the lids leak if tipped over?
The lids are straw friendly with a removable gasket but are not fully sealed locking lids, so avoid tipping to prevent spills.

Can these be engraved or laser marked?
Customers report good engraving ability on the powder coated surface, making them suitable for personalization or sequential coding.
