Patagonia thought of it all with their Snow Pile Bib Pant. A motley of features ensures they stay warm even when moisture or wind knocks on the bib's doors. Built-in gaiters slide over their boots making sure no powder can pry its way in. A specialized membrane and insulation ensure warmth in wind and wet snow. Our favorite part is the built-in leg extensions so even if they manage to grow another two inches that year the Snow Pile can accommodate.
