The GulTrek TPU soft flask is designed for active users who need a reliable, space-saving water bottle. Made from BPA-free TPU and silicone, it remains flexible and odorless. Available in three capacities (250ml, 350ml, 500ml) and multiple colors, it can be easily collapsed when empty to fit in a pocket or pack. The bite valve allows one-handed drinking without stopping your activity. Customization options are available for brands.

Our TPU water bottles are manufactured with practical features in mind: a leak-resistant design, a wide temperature tolerance (-20°C to 50°C), and a compact foldable structure. We support OEM/ODM orders including custom colors, capacities, and logo application. This makes our soft flasks a versatile hydration solution for runners, cyclists, and hikers – ready for your brand label.
