  • Description

    Merlin have always offered high quality gear at competitive price points, but they have truly outdone themselves with the Neptune trousers (and compatible jacket). The Neptune trousers use materials and techniques usually only found in motorcycle garments at a much higher price point. The outer layer is made from abrasion resistant 700D polyester perfect for the urban commuter. This outer layer is backed up by a waterproof and breathable Reissa Active membrane, one of Reissa's higher rated membranes which keep you dry and comfortable. The Neptune trouser has a full length 125g thermal liner which can be removed on warmer days. When it gets even hotter the Neptune will still be your go-to trouser because of the zipped air vents. It comes equipped with CE level 1 armour in the knees and there are pockets for optional hip protection. Please check the full spec list and in-depth video review below. You won't find a pair of trousers of this quality at a similar price.
