Unfortunately almost every season heralds the transition of children from one size of clothes to the next, which usually means replenishing their wardrobes, rainwear and all. But with all the styles, sizes, colors - and especially the prices - of raingear made by Swell-Wear, there isdefinitely cause for hope. Swell-Wear is designed with growing children in mind, being made to fit toddlers through size 14. There are roomy hooded reversible ponchos, reversible traditional-style zip-front coats with hoods, short slickers and even ponchos and zippered coats decorated with Snoopy emblems (It's the only rainwear licensed to use the Snoopy design). The ponchos are perfect for protecting bulky winter coats from rain and snow. All are made of waterproof materials and each style is available in several colors, some in plaid. With the prices as reasonable as they are (from $3 to $11.50), there's no reason to go broke as the kids grow up.
