REI Outlet offers the Uvex Viva II Bike Helmet in White or Black for $29.73. Opt for in-store pickup to dodge the $5.99 shipping charge. That's $20 off and the lowest price we could find, although we saw this for $8 less last December. Features include 16 vents, moisture-absorbing hypoallergenic pads, a monomatic comfort closure, and removable snap-fit visor. It's available in size 52-57cm.
