550ml / 850ml Single Wall Aluminum Water Bottle, Thickened Eco Portable Sports Flask, Small Mouth Sublimation Blank Water Bottle with Stainless Steel Lid for Outdoor Travel Gym

This outdoor flask is crafted from thickened food-grade aluminum material, much lighter than stainless steel bottles, which eases the burden during hiking, cycling, camping and daily commutes. The aluminum material features excellent corrosion resistance, safe for cold water, fruit juice, iced sports drinks and other cold beverages. The matte spray coating on the outer wall delivers soft touch, fingerprint-resistant and long-lasting color fastness.

The narrow small-mouth threaded opening effectively prevents water splashing when moving or drinking outdoors. The matched stainless steel cap is equipped with a food-grade silicone gasket inside; after fully twisting the lid closed, the bottle is completely spill-proof, allowing you to put it directly into backpacks or gym bags without leakage risk. The smooth threaded structure is durable for repeated opening and closing.

The smooth blank aluminum surface is perfectly compatible with heat transfer sublimation, silk screen printing and laser engraving. You can print full-color patterns, brand logos, slogans or personalized photos on the bottle body. We also offer custom coating color service per Pantone codes, making it ideal promotional merchandise for fitness studios, corporate events, outdoor clubs and souvenir gifts.
