Keep the style casual and your legs both warm and dry with the boys' Burton Barnstorm 2L Pants. DRYRIDE two-layer fabric with fully-taped seams provides a barrier against snow and other moisture. In contrast, Thermacore insulation provides reliable all-winter warmth, and there's still plenty of room to layer. The Room-to-Grow system allows limbs to expand at the seams to outlast growth spurts. These pants are a bluesign product, which means it's approved to meet the highest safety standards for both people and our planet.   FEATURES: The regular fit is just right: Not too tight or too baggy. DRYRIDE fabric [10,000mm/5,000g] is highly breathable, waterproof, and quick drying; PFC-free DWR coating. ThermacoreECO insulation [60g] is lightweight and breathable, providing a super-comfortable feel and low-bulk warmth that cranks the heat and dries quickly. It's bluesign approved and features over 90% recycled fibres that provide long-lasting durability and all-around easy care; Nylon taffeta lining. Room-to-Grow system extends the length of the legs by 1.5in to keep up with growth spurts. Zippered thigh pocket, microfleece-lined hand-warmer, and back pockets with hook-and-loop closure.
