The DryVent material used in these pants by The North Face provides full protection against the elements while remaining breathable. Thanks to the 2.5-layer construction, the Sheltered Creek pants pack down to a small size and are exceptionally lightweight, both when worn and when carried in a backpack. 2.5-layer pants are designed to be worn with long underwear or tights, but in the middle of summer, they can also be quickly pulled over shorts as a rain shell. For heavy-duty use in dense undergrowth, we recommend more robust pants, as the Sheltered Creek pants are high-performing but have a thin outer fabric to reduce weight. - Regular fit - Waterproof, windproof, and breathable material - DryVent membrane - Zippers from below the knee for easier dressing - Elastic waistband with drawstring adjustment - Adjustable Velcro straps at the leg openings This product does not contain PFC compounds.
