The Defend Fire Pants are water-resistant, fleece-lined MTB pants built for tough conditions. Featuring Polartec® Alpha® insulation, these pants keep you warm on cold rides while remaining breathable so you can keep riding even as you build up a sweat. The DWR (Durable Water Repellent) treatment repels moisture on damp trails. The slim silhouette and tapered lower leg provide a race-ready fit that reduces snags and drag. The proven race-ratchet closure keeps them snug while making fit easily adjustable on the fly.
