Hydro Flask 28 Oz All Around Tumbler Straw Lid Trillium - Cold

In this review of the Hydro Flask 28 Oz All Around Tumbler Straw Lid Trillium the bottom line is simple: this insulated straw tumbler is for people who want a cup that keeps cold drinks cold, feels solid in the hand, and fits most cupholders. The standout reason to buy is the TempShield double-wall vacuum insulation that reliably keeps beverages chilled for hours while the press-in straw lid provides an easy sipping experience without needing to remove the lid. The review focuses on daily carry, outdoor use, and simple cleaning.

Key Features

• Straw Tumbler: The 28 oz capacity handles smoothies, lemonade, or iced coffee so you can use one cup for many drinks without constant refills.
• Cold Stays Cold: Double-wall vacuum insulation with TempShield keeps cold drinks chilled for hours, so ice lasts longer on hot days.
• Leak-Resistant Lid: The press-in, flexible straw lid is designed to be splash-resistant and keeps your drink ready to sip without removing the lid.
• Cupholder-Friendly: The tapered, cupholder-friendly design means it fits in most car cupholders for easier travel and commuting.
• Pure Taste: Durable pro-grade stainless steel prevents flavor transfer so yesterday's drink won't affect today's beverage.
• Comfortable to Hold: The tumbler's shape and finish feel good in hand and make it easy to carry between errands or to the gym.

Who It's For

This tumbler is well suited for commuters, outdoor enthusiasts, and anyone who wants a reliable insulated cup for cold drinks. The 28 oz size is generous without being bulky, so it works for long walks, road trips, and all-day hydration where keeping a beverage cold matters.

Those who need a fully leakproof bottle for packing sideways in a bag or who prefer a straw-free, spillproof travel lid might look elsewhere; the press-in straw lid is splash-resistant and generally leak-resistant but is not a fully sealed screw-top designed for upside-down storage.
