Supremely lightweight, breathable and packable alpine shell waterproof.

The Minimus 777 Jacket is a revolutionary lightweight and breathable 3 layer waterproof jacket. Engineered for fast moving activities where weight saving is essential. Utilising an exclusive PERTEX® Shield+ laminate which combines a 7 denier nylon face, a 7 micron breathable membrane and a super light 7 denier tricot backer. Critically designed to save weight without compromising functionality; weighing only 140g with micro-taped seams to increase breathable surface area and a 12-13 seam stitch count for tight, clean and strong seams throughout compared to an industry average of only 8. Pre-elasticated under-helmet hood, articulated arms and a tiny pack size into its own pocket makes it perfect for any alpine trip.

Centurion Review: What sets this jacket above the rest of the lightweight mountain shell offerings on the market is the ratio of weight vs waterproof level vs breathability. This jacket weighs just 140g, offers a 20000mm Hydrostatic Head and a 30,000g/m2/24hrs Breathability rating. That makes it lighter, more waterproof and more breathable than any other jacket we have tested. The price tag reflects the level of product. Without going to gore-tex this is as good as you will get from a lightweight waterproof.
