“The Trenches Hydro in Slime is my 5th Melin hat. They’re great, especially if you have a big head like me. I have 4 hydros and one thermal, all trenches and overall they have all been great. Only complaint is there is some inconsistency in fit. Two of the four hydros are perfect, the depth is just right and sits just behind the ears. The other two are shallower and feel like they don’t come down quite as far as they should. Other than that, these hats are the best. Will be buying more.”
