The only limits your free wheeling son seems to recognize are not fighting with his sister, no throwing food at the table, and wearing a helmet when ripping tricks or hucking off cliffs is non negotiable. It's a good thing the folks at Marmot designed the Boys' Freeride Pant to meet your boy's high adventure demands. Waterproof and breathable fabric gets a little extra oomph from taped seams and Thermal R insulation, so your snow monster may continue his reign of terror without suffering the ill effects of being cold and wet. Two layers of waterproof and breathable MemBrain fabric encase Thermal R insulation for long lasting warmth. The seams are taped to eliminate micro openings to make the Freerider pant truly waterproof. Articulated knees mean less fabric billowing around his knees for improved mobility. Internal gaiters with gripper elastic maintain a close relationship between this pant and his boot throughout his high mountain horseplay. Blue moons are more common than your kiddo making a mid day pit stop, so the zip fly and snap closure will come in handy when he's taking care of business mid mountain. Scuff guards complete a full lap around his ankles and hand pockets zip shut for secure holding of his most essential things, mini mints and lip balm. You might be able to eke two seasons out of the Freeride pant with Marmot's Kids Grown an Inch cuff. With a simple snip, you can extend the length of the cuff by an inch when he shoots up mid season or over the summer.
