L.L.Bean Snowfield Bibs
Here's what other sites are saying:
Everything you want in winter bibs for kids they're waterproof, windproof and exceptionally warm. We've switched to a new fabric that's lighter in weight so it's easier to move around in, but still tough enough to stand up to kids' play. Waterproof TEK2.5 polyester fabric with fully taped seams to seal out snow and slush. Premium 3MTM ThinsulateTM Insulation polyester provides superior warmth without a lot of weight. Zip-front bibs have an elasticized waist and adjustable straps for a secure fit. Seat and knees are reinforced for extra durability. Internal nylon gaiters keep snow and ice out; zip vents at hems fit easily over boots. Smooth nylon lining. Imported. Machine wash and dry.
