Rab Men's Firewall Pants — Waterproof & Breathable Shell for Hiking & Climbing | Black, S/32

Rab Men’s Firewall Pants: Waterproof, Breathable Shell for Mountain Adventures

When you’re pushing through mist and wind on a rugged ridge, you want lightweight protection that moves with you. The Rab Men’s Firewall Pants deliver robust weather coverage in a compact, packable shell. Built with Pertex Shield 3L fabric, these rain-ready pants strike a balance between rain protection, breathability, and easy layering for changing conditions on the trail or crag.

Think of a slimly tailored layer that fits over midweight base layers and lightweight insulation without bulk. The regular fit and thoughtful engineering minimize bulk while maximizing mobility so you can keep pace with friends, tackle steep inclines, or skim past exposed rock faces without feeling restricted.

All-Weather Protection

Key protection comes from a waterproof rating of up to 20,000mm and breathability rated around 20,000 g/m². This combination helps ward off rain while allowing moisture to escape, helping you stay more comfortable during long days outdoors. The shell is designed to be highly packable, so you can stash it away when the sky clears and you’re ready to hike lighter on the next leg of your trek.

• Pertex Shield 3L shell for durable waterproofing and wind resistance with lightweight, recycled fabric.
• High waterproof and breathability ratings support varied mountain weather and fast-moving activities.
• Compact packability makes it easy to bring along as a backup layer.

Fit, Mobility, and Layering

The Firewall Pants offer a regular fit that comfortably accommodates mid-layer insulation without restricting movement. A full-length gusset and articulated knees provide freedom when you’re scrambling, climbing, or navigating technical terrain. ¾-length side zippers enable easy on/off over boots in sudden showers and also double as vents for temperature control. An elastic waistband with a drawcord helps you customize the fit, while adjustable hems stay secure above footwear on muddy trails.

• Regular fit with a full-length gusset and articulated knees for enhanced mobility.
• ¾-length side zippers for easy layering and ventilation.
• Elastic waistband with drawcord and adjustable hems to reduce bulk and mud intrusion.

Materials and Sustainability

The shell uses a 40D 100% recycled nylon construction with a lightweight PU coating, combining durability with responsible material choices. The fabric’s bonded waterproof and breathable performance helps protect you during damp rides or misty ascents, while the compact build supports easy packing for multi-day trips or weekend adventures.

Practical Use Scenarios

These pants are designed for hikers, scramblers, and climbers who encounter changing weather. They work well on alpine routes, forested trails, and exposed ridgelines where rain and wind are common. Pair them with a waterproof jacket or fleece mid-layer to tailor warmth and protection for your specific day out.

Care and Maintenance

To preserve waterproof performance, wash with a gentle detergent and air dry. Avoid fabric softeners or high heat, which can affect the fabric’s breathability and water-repellent finish over time.
