Hydro Flask Travel Tumbler 24 oz Tonal Trillium — Insulated Stainless Steel with Handle & Straw

The Hydro Flask 24 oz Travel Tumbler in Tonal Trillium is an insulated stainless-steel cup with a handle, leak-resistant straw lid, and cupholder-friendly shape for all-day cold hydration.

Engineered for everyday use, this 24-ounce Travel Tumbler blends double-wall vacuum insulation with a flexible straw lid and a sturdy handle so you can carry, sip, and stow your drink with minimal fuss. The tonal finish and color-matched lid and straw create a unified look while practical details—like a press-in lid designed to reduce leaks and a size that fits most cupholders—make it convenient for commutes, workouts, and travel.

How well does this tumbler keep drinks cold?

The Hydro Flask Travel Tumbler uses TempShield double-wall vacuum insulation to minimize heat transfer and preserve cold temperatures for hours. While exact duration depends on ambient conditions and how often the lid is opened, it's designed to keep chilled drinks noticeably colder than single-wall alternatives.

• Double-wall vacuum insulation reduces warming from outside heat.
• Stainless-steel construction resists temperature transfer and odor retention.
• Tight-fitting press-in lid helps maintain internal temperature when closed.

Is the lid leak-resistant and easy to drink from?

The flexible straw lid is designed for comfortable sipping and is soft on teeth, while the press-in design reduces accidental spills when upright. It's not fully sealed like a threaded, leakproof cap, so you should still avoid tipping the tumbler when it's full.

• Flexible straw allows varied drinking angles and gentle contact.
• Press-in lid limits splashes during normal use.
• Simple assembly and disassembly for cleaning and maintenance.

Will this fit in my car cupholder and how portable is it?

The 24 oz profile was shaped to slide into most standard cupholders while offering substantial capacity for extended outings. A reinforced, ergonomic handle makes hand-carrying comfortable and prevents drops when navigating crowds or carrying other items.

• Tapered base fits the majority of vehicle cupholders.
• Durable handle for secure carrying on the go.
• Stainless-steel body balances weight and durability for travel.

What makes the Tonal Trillium design different?

Tonal Trillium pairs a monochrome color scheme with color-matched lid and straw and a tonal logo, offering a cohesive, understated appearance. The finish is built for daily wear, combining style with the brand’s rugged materials.

• All-matching lid, straw, and logo for a single-color aesthetic.
• Durable powder coat resists scratches and improves grip.
• Neutral, versatile shade that works in casual and active settings.

Who this is for: This Hydro Flask 24 oz Travel Tumbler suits people who want a mid-size, reusable cup that fits a busy, mobile lifestyle—commuters, students, coaches, and anyone who needs reliable cold-holding performance without sacrificing style. It’s ideal if you value a comfortable handle, easy sipping with a flexible straw, and a design sized to fit most cupholders for daily travel.
