Just in time for summer, the retail chain Eddie Bauer is rolling out Capri pants, camp shirts, swim trunks and hats that offer sun protection of up to UPF-50--all in comfortable, breathable fabrics. The average T shirt, according to some dermatologists, often isn't tightly woven enough to block out rays. Meanwhile, the new Buzz Off line of apparel, made by Ex Officio, staves off mosquitoes, ticks and other insects through at least 25 washes and offers UPF-30 sun shield.
