Softflask KADVA Flowbie 150 ml blue (KDV-NAB5C022-BL)

Softflask KADVA Flowbie 150 ml combines modern synthetic materials, resistance to mechanical damage, and thoughtful design solutions, making it suitable for both short training sessions and longer trips. The 150 ml capacity makes it an ideal complement to larger hydration systems or an alternative for short distances. It fits well in the hand and easily fits into the pocket of a running belt, vest, or small backpack.

Compact and flexible form

Designed from flexible thermoplastic material (TPU), the softflask body freely adapts to the user's hand and reduces its volume as the contents are emptied. This limits unnecessary fluid movement inside the container and minimizes the "sloshing" effect often found in rigid bottles. This is especially important during dynamic activities such as trail running or cycling in challenging terrain. The soft construction also facilitates storage – an empty flask can be folded and stored even in a very small pocket.

Durability and safe materials

Only high-quality materials approved for contact with food were used in the construction. The body and opening are made of durable TPU, characterized by resistance to damage and flexibility even at low temperatures. The polypropylene (PP) cap ensures tightness and thread durability, while the inner polyethylene (PE) layer limits the transfer of odors and tastes, guaranteeing the neutrality of the fluids stored inside. The soft silicone valve allows comfortable drinking without the need to remove the cap – just a slight squeeze of the flask directs the liquid straight to the user's mouth.

Usage limitations and recommendations

The product is not intended for carbonated drinks, as the increase in pressure inside the flask may lead to leakage or valve damage. Avoid washing in a dishwasher – high temperatures and strong detergents may degrade the insulating properties of the material and damage the lid. The softflask is also not suitable for use in a microwave oven due to metal components present in the cap or valve system. Following these recommendations will help maintain the product's durability and functionality for longer.

Leak-proof and convenient in the field

The cap is precisely matched to the flask opening, ensuring complete tightness – even with intensive use and horizontal carrying. Thanks to the flexible walls, the flask is easy to squeeze, and the silicone valve responds to light pressure, eliminating the need to unscrew and screw the bottle back on during running or cycling. This design allows for quick hydration on the move without interrupting activity, which is crucial for user performance and comfort.

Low weight and high mobility

Thanks to its compact dimensions and 150 ml capacity, the flask is lightweight yet sufficient to provide short-term hydration during sports activities. It works well as a backup container for isotonic drinks or water, which can be quickly accessed and used without reaching for the main bladder. Ideal for short-distance runners, mountain hiking enthusiasts, and as an additional fluid source during post-training recovery.
