"What Our Gearhead® Experts Are Saying: ""I’ve seen the Sierra Insulated Bib handle everything from first chair to sledding in the backyard. The infiDRY fabric keeps kids dry without making them overheat, and the infiLOFT insulation is reliable for warmth. I especially appreciate the Youth Evolution feature—being able to extend the legs means it lasts through growth spurts, which saves parents money in the long run.""We trust the 686 Sierra Insulated Bib to keep the youngest riders warm and dry through every winter adventure. Built with a waterproof infiDRY membrane and critically sealed seams, this bib keeps snow out while still allowing breathability. Its lightweight infiLOFT insulation holds warmth even when damp, ensuring all-day comfort from morning lessons to afternoon laps. Thoughtful details make the Sierra a standout choice for growing riders. Stretch side panels encourage easy movement, elastic suspenders adjust for the perfect fit, and gaiters keep boots sealed against snow. Reinforced hems and kick panels add durability for seasons of play, while the Youth Evolution feature extends the legs by 1. 5 inches to handle growth spurts. It’s a bib designed to keep pace with active kids who live for winter days outside."
