The FLSK thermo bottle is an innovative stainless steel water bottle, which has a high insulating capacity and keeps the drinks hot for 24 hours and cold for 18 hours. Ideal for a hot tea during a cold day of skiing, or a cold beer on the summit.
The FLSK insulating bottle is also 100% leak-proof thanks to its narrow spout and a very tightly fitting lid, which makes it absolutely leakproof even with carbonated drinks.
The FLSK is also shock-resistant, tasteless and looks really good. Through a great color selection everyone will find their favorites!
