Warm legs, no bulk.
The Rab Men’s Xenair 3/4 Pants brings active insulation to the lower body without the penalty of traditional down or heavy synthetic fill. Pertex Quantum Air 20D fabric at 47gsm wraps PrimaLoft Gold Active+ insulation at 80gsm for a package that breathes during high-output movement and insulates when pace drops. Articulated knee construction and a deep stretch waistband with drawcord keep the fit dynamic and non-restrictive across technical terrain, while stretch fleece panels in targeted areas add mobility where needed. Three-quarter length is ideal for pairing with hiking socks or gaiters, and quilted construction creates a clean, efficient loft across the full pant.
