Excellent cap for those who, like me, suffer from sinusitis because it can be used both cold and hot. Perfect fit, does not tighten
Fine article, fits well. However, description is wrong. There is not 360 ° gel, but only over half (which is sufficient for migraines, but not correct with the description) and really does not stay cold for 15-20 minutes, at most 5-10 minutes.
Article arrived in France in 3 Weeks and according to the photos.
Effective but the cold lasts 15 to 20min knowing that I only took the frost in front, maybe it would last longer if there is some in front and behind.
