The Columbia Toddler Boys' Buga Set pairs a winter jacket with bib pants for snow play. Omni Tech equips both the jacket and the pants with waterproof breathable protection, and taped critical seams prevent snow from seeping through in places most likely to let wetness in. Columbia's Omni Heat thermal reflecting lining and insulation give the jacket plenty of warmth, while the bib pants' microfleece lining offers a touch of warmth as well as smooth softness. Columbia's OutGrown grow system lets you extend the jacket and bib pants' sleeves and legs so he can play in this set next season, even after he grows a few inches. The bib pant has adjustable suspenders for a secure fit, and internal leg gaiters keep snow out of his boots. Hammerhead nylon reinforces the seat and legs for long lasting durability, and 360 degree reflectivity helps keep him visible in low light conditions.
