説明

Some objects hold heat. This one holds ritual. The Vanguard Flask was designed for the small ceremonies that structure a demanding day: the 6 a.m. tea that steadies your hands before the first meeting, the ice-cold water waiting after a two-hour workout, the herbal infusion that closes the evening. Inside its double-wall vacuum body, a food-grade SUS316 stainless steel chamber holds temperature for 6 to 12 hours, so the tea you pour at dawn is still honest at noon and the water you chill at lunch is still cold at the final bell.

Most thermoses hide their engineering. The Vanguard wears it with intent: an inner wall of 316 stainless steel, the same alloy trusted in surgical instruments, wrapped in a 201 stainless shell that shrugs off drops, scuffs, and the chaos of a commuter bag. The wide mouth accepts ice cubes, tea leaves, and a cleaning brush with equal ease, while the integrated stainless steel tea strainer lets you steep loose-leaf tea properly instead of fishing leaves out of your drink with your teeth.

Details are where a daily object earns its place. The 304 stainless and food-grade PP lid seals without a fight and opens one-handed. The anti-slip base uses a concave-convex structure that refuses to slide across a desk or car console. Choose the 600ml size for a commute or the 800ml for a full workday, in white, black, pink, green, or purple, and let the flask match the identity of its owner rather than the other way around.

This is not a cup. It is a small promise of temperature kept.

Application Scenarios

The Vanguard Flask earns its place across the full arc of a day. The commuter pours coffee at 7 a.m. and finds it still hot at noon, because 6-12 hours of vacuum insulation does not negotiate with a busy calendar. The office worker brews loose-leaf oolong through the integrated strainer and measures a meeting by the tea left in the cup. The gym-goer fills the 800ml body with ice water before a session and drinks cold, clean hydration after the last set. The traveler crosses time zones with one familiar thermal companion, and the student keeps a 600ml flask on a desk that has no room for a mug collection. Every scenario shares the same quiet arithmetic: fill it once in the morning, and the temperature you chose is the temperature you get.

Frequently Asked Questions

Q: How long does the Vanguard Flask keep drinks hot or cold?

A: The double-wall vacuum construction holds temperature for 6 to 12 hours depending on fill volume and ambient conditions, which comfortably covers a full workday or a long commute.

Q: Can I brew loose-leaf tea directly in the flask?

A: Yes. The integrated stainless steel tea strainer is designed for loose-leaf steeping, so you can brew real tea without tea bags and without leaves floating in every sip.

Q: What materials touch my drink?

A: The inner chamber is SUS316 stainless steel, and the lid uses 304 stainless steel with food-grade PP, both certified to CE, FCM, LFGB, and SGS food-contact standards.

Q: Is the lid safe with very hot liquids?

A: Yes, but please allow freshly boiled water to cool below 60 degrees Celsius before sealing the lid tightly, since trapped steam pressure can build up inside a vacuum flask.

Q: Which capacity should I choose?

A: The 600ml size suits commutes and bags, while the 800ml covers a full workday or long outdoor sessions. Both share the same insulation performance.

Q: Is the flask leak-resistant in a bag?

A: The 304 stainless and PP lid seals securely, and the anti-slip base adds stability. For best results, keep the flask upright and avoid overfilling.

Great insulation, lid could be smoother

The SUS316 liner feels genuinely premium and insulation is exactly as advertised, hot all day. Only nitpick is the lid threads felt a little stiff for the first week before they broke in.

Cold water stays ice cold

Filled it with ice in the morning and the water was still cold after a two-hour gym session plus the drive home. The wide mouth takes ice cubes easily and the anti-slip base stays planted on the car console.

Tea stays hot through a full shift

Brewed loose-leaf oolong at 6 a.m. and it was still steaming at noon. The integrated tea strainer actually works, no leaves in the mouth, and the 800ml size is right for a 12-hour hospital shift.
