Can the neoprene bottle bags be washed? What are the key points to consider for daily cleaning and maintenance?

The neoprene cup sleeves are designed for easy removal for cleaning and maintenance, meeting the hygiene requirements for sauna scenarios.

How to clean: The cup sleeves can be removed directly. Rinse them with clean water and neutral detergent(optional) to remove sweat, steam stains, etc. that remain from the sauna environment. After drying, they can be used again; the stainless steel insulated cup can be rinsed with clean water or cleaned with a soft brush. It is also suitable for washing in a dishwasher (it is recommended to hand wash the cup sleeves separately to avoid deformation from high-temperature drying).

What to notice:

Avoid soaking the cup sleeves in high tempratured boiling water for a long time (≤30 minutes).
Do not use sharp objects to scrape the cup sleeves or the surface or both inner and outer lining of the insulated cup (to prevent damage to the insulation performance or appearance)
The insulated cup should not be used to hold strong acid or strong alkali liquids for a long time.
If water scale appears after long-term use, soak it in a diluted white vinegar solution for 30 minutes before rinsing, and it will be restored to cleanliness.

How effective is the heat retention of your sauna hydration cups? Can it be used in high-temperature environments, while still maintaining a stably low temperature for the drink?

Our bottles adopt a double-layer vacuum stainless steel insulation structure, combined with a neoprene cup bag for auxiliary heat insulation: The insulation duration can reach 6 to 12 hours. After pouring ice water(approx. 0℃) under normal temperature, the water temperature will be 0-10℃ within 6-12 hours);

Core advantage for the sauna room scenario:

The vacuum insulated stainless steel walls can block the heat exchange between inside and outside, which prevents the cold water in the bottle from rapidly heating up, meeting the need for replenishing freshly cool water at any time during the sauna process.
Since the stainless steel bottle outer wall is exposed to high temperatures, it is prone to overheating, and neoprene bottle sleeve prevents direct contact between the cup body and the hand, maintaining touch temperature under 40℃.).
Plus, the sealing performance of the insulated bottle is excellent, and the high-temperature steam in the sauna room will not penetrate into it to contaminate the beverage, balancing both insulation and usage safety.

Is the material of your sauna water bottles safe? Will the bottle sleeves release harmful substances in the high-temperature sauna environment?

The core materials of our products have all passed food-grade safety certifications, ensuring safety without any risks:

The inner lining of the bottle is made of food-grade 304/316 stainless steel, which has been certified by both FDA and LFGB. It can withstand high temperatures (-20℃ to 120℃), is lead-free and chromium-free, ensuring safe drinking experience;
The bottle sleeves mostly use high-quality neoprene (other customized materials are also available), and have passed high-temperature aging tests. They will not deform, release odors or harmful substances in the sauna environment of 80℃ to 100℃.
At the same time, they have excellent heat insulation and anti-scald properties. When holding, they can effectively isolate the heat from the bottle body, avoiding hand burns.

What is a Sauna Water Bottle?

It is a product combination specially designed for high-temperature and high-humidity sauna environments: consisting of a stainless steel insulated bottle and a neoprene bottle sleeve. Unlike ordinary water bottles, it has been specially designed to meet the unique needs of sauna users, mainly to maintain the beverage at a low temperature, prevent the outer wall from scalding the hands, and ensure safety in extremely high temperatures. It is an essential accessory for sauna rooms, allowing users to conveniently replenish water during the sauna session and enhancing their experience.
