The Salewa Puez GORE-TEX® 3 Layers Jacket is a men's hardshell rated at 28000 mm water column, weighing about 400 grams in a 139 gram per square metre laminate. Three layer means the membrane is bonded between face fabric and backer with no loose lining, which is what makes a shell of this protection level this light.

• 28000 mm water column: well beyond the level at which a fabric counts as waterproof, so it holds up under sustained rain and pack pressure.
• Three layer laminate, 139 g per square metre: face fabric, GORE-TEX® membrane and backer bonded as one, with no separate lining to add bulk.
• About 400 g: light for a full protection hardshell, which is the practical argument for three layer construction.
• Breathability rated RET below 20: a lower RET number means more moisture passes through, and this is the more protective rather than the most breathable end of Salewa's range.
• Puez is the trekking line: Salewa's mountain hiking family rather than its technical alpine range.
• Compare with the two layer version: the 2L Puez jacket has the same waterproof rating but breathes better and weighs more, so the choice depends on the use.
