Are there temperature regulations for your products?

The recommended temperature suggestions for our products are:  

33 degrees Fahrenheit/1 degree Celsius 
140 degrees Fahrenheit/60 degree Celsius  

Note that if any LifeStraw has water in it and is stored in freezing conditions, the creation of ice within the membrane can damage the filter by expanding the pores with the expansion of the ice.  This would render it unusable, and you would need to replace it.

We recommend keeping LifeStraw products, specifically the membrane filters, close to your body when hiking or traveling in freezing temperatures to ensure any water or vapor inside the filter does not freeze.

For long-term storage, store these somewhere at room temperature.
