The Helium Rain Pants deliver lightweight, waterproof, and ultra-packable flash storm protection for peace of mind when traveling in unpredictable weather conditions.
Crafted with bluesign® approved Pertex® Shield fabric, the Helium Rain Pants are waterproof, windproof, and breathable, ensuring comfort and dryness in soggy conditions. The gusseted crotch provides unrestricted movement, and ankle zippers make for quick changes over boots.

The elastic waistband with drawcord and gripper tape ensures a snug, no-slip fit, and the reflective logo ensures visibility in low-light conditions. With a standard fit that accommodates layering, these pants are a versatile ally against unpredictable weather.
Purpose-built to pack light, move fast, and stay dry in unpredictable conditions, the Helium Rain Pants are an essential addition to any backcountry kit.
