Part of MEC's Boundary collection, the Steepside combines backcountry-grade insulation with slope-ready aesthetics.

The fully adjustable hood features a stiffened brim to keep your vision unobstructed during flurries and on bluebird afternoons. Ideal for resort or side riding, the Steepside encourages free-form shredding through all-mountain conditions.

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.

Waterproof with fully taped seams
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.

Length Below hip
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.
