Rab Men's Downpour Pants - Waterproof & Breathable Rain Pants for Hiking (Black, Large/30in)

Storm-ready performance for outdoor adventures

The Rab Men’s Downpour Pants are crafted to handle sudden storms on rugged trails. With a slim, light Pertex Shield 2.5L shell, they pair reliable waterproofing with breathability in a compact, packable package. Designed for hikers and trekkers who value quick-on capability, these pants are built to layer over base layers and midlayers as weather changes on the mountain or in town.

Key benefits at a glance

• Pertex Shield 2.5L shell delivers a balance of waterproofing and light weight, with recycled fabric for a lower environmental footprint.
• Waterproof and breathable ratings support comfort during variable conditions, from mist to downpours.
• Regular fit with a full-length gusset and articulated knees promote unrestricted movement on steep climbs and loose scree.
• Three-quarter length side zippers allow easy on/off over boots and provide adjustable ventilation when you warm up.
• Part-elastic waistband and drawcord-adjusted hems keep the pants secure over hiking footwear and reduce bulk under other layers.

Designed for real-world hiking and trekking

The Downpour Pants are built to adapt as you move—from quick summit pushes to rugged ridge traverses. The gusseted construction and articulated knees help you maintain stride length without feeling restricted, while the zipper vents offer a simple way to control airflow on exposed ridgelines. Layering is straightforward thanks to the regular fit and the lightweight shell, which tucks away neatly when you don’t need them.

In wet weather, the drawcord-adjusted hems stay secure over footwear, helping to seal out dirt, gravel, and splashes. The result is a practical, everyday rain pant that can accompany you on a variety of outings, from forest loops to alpine days that end with damp shoes and a hot drink at the trailhead.

Materials, care, and sustainability

Crafted from 50D 100% recycled polyester with a fluorocarbon-free DWR finish, these pants aim to balance performance with responsibility. The fabric is designed for durability, while the shell’s compact packability makes them easy to stash for unexpected showers. Weight and packability are optimized for hikers who value efficiency in the backcountry.
