The Dynafit Alpine 3-Layer Jacket is a women's waterproof shell from Dynafit's trail running line, built in a three layer laminate. Three layer means the membrane is bonded between the face fabric and a backer, which gives a shell that is lighter and packs smaller than a lined two layer jacket of the same protection.

• Three layer construction: face fabric, membrane and backer bonded into one, so there is no loose lining to add weight or trap air.
• Waterproof and breathable: a running shell has to shed rain while releasing the heat of a hard effort.
• Alpine is the running line: Dynafit's Alpine family is trail running, so the cut is close and the weight low rather than roomy for layering.
• Packs down small: the kind of shell that is meant to live in the back of a running vest until the weather turns.
• Women's cut
• Cloud Blue colourway
