Bosi 304 Stainless Steel Insulated Water Bottle – 450ml
The Bosi 450ml insulated water bottle uses food-grade 304 stainless steel double-wall vacuum construction to keep beverages hot for up to 12 hours and cold for up to 6 hours. At 450ml, it fits standard cup holders and most bag side pockets, making it practical for commuting, office desks, gym sessions, and outdoor use.
Key Specifications
- Capacity: 450ml (approx. 15.2 fl oz)
- Material: Food-grade 304 stainless steel (interior & exterior)
- Insulation: Double-wall vacuum – hot up to 12 hrs, cold up to 6 hrs
- Dimensions: 71mm × 96mm × 203mm (W × D × H)
- Available Colors: Black, Red, Olive, Turquoise
- Ideal For: Office, commute, home, travel, gym
Why 450ml Works for Daily Hydration
At 450ml, this bottle holds roughly two standard servings of your preferred beverage — enough for a morning commute or a focused work session without the bulk of larger 750ml+ bottles. The slim profile (71mm diameter) slides into most laptop bag side pockets and standard vehicle cup holders.
Tradeoff to note: For all-day hikes or extended outdoor activities, a larger 750ml bottle may better suit high-fluid-demand scenarios. For everyday desk-to-commute use, 450ml is the practical sweet spot.
Material & Build Quality
The interior and exterior are both 304 stainless steel — a food-safe alloy resistant to corrosion, odor absorption, and flavor transfer. The double-wall vacuum layer eliminates condensation on the outer surface, keeping your hands dry and your bag protected.
