MEC Alpine Ally Jacket - Men's
A minimalist shell that packs down small to fit in a travel bag or an alpine pack. In coastal climates or fast-changing mountain weather, it offers protection from storms and persistent rain. The design features deep pockets where you can stash accessories, and a hood that adjusts for coverage, mobility and a clear view of the way ahead. MEC chose Pertex Shield + for the Alpine Ally, as it presents both reliable outdoor performance and accessible value. With a versatile cut, you can use this jacket for climbing, hiking and skiing, or any outing when mixed weather is in the forecast.
- 3-layer Pertex Shield + is treated to shed water and taped through the seams for full waterproof protection.
- Clean, stitch-free construction is light and offers unrestricted movement.
- Helmet compatible hood has 3-way adjustments (left, right and front to back).
- Chin guard prevents chafing.
- Underarm zips provide venting options.

- Pocket zippers are very water resistant, but not waterproof, so we don't recommend them for electronics or other valuables.

Fabric waterproof rating
The standard test for waterproof fabrics uses a standing column filled with water. The figures given are the water column height. A rating of 3,500mm or higher can be considered waterproof. The higher the rating, the more durable the waterproof fabric will be over time.
Waterproof garments use waterproof-breathable technologies and are fully seam-taped. Water-resistant garments use waterproof-breathable technologies but their seams are not taped. Water-resistant garments repel water and protect against wind but are not made of waterproof fabric.

Fabric active breathability
The rate at which a waterproof breathable fabric expels moisture when the inner surface is moist from perspiration. Values under 8,000g/m2/24h provide low performance, 20,000g/m2/24h provide moderate performance and values over 30,000g/m2/24h provide high performance.
A windproof garment does not allow any air to permeate the fabric. A garment with windproof panels has panels of fabric that are totally windproof, but the rest of the garment may not be windproof. A wind-resistant garment resists some wind, but not as much as a garment that is windproof.
Durable water repellency
Usually referred to as DWR. A treatment made to fabrics that causes water to bead and run off instead of soaking through.
