REI Outlet offers the Kavu Women's Briar Insulated Vest in Winter Pines for $41.73. (6pm charges $25.99 plus $3.95 for shipping, although it's in limited stock just pennies more.) Opt for in-store pickup to avoid the $5.99 shipping charge. That's the lowest in-stock price we could find by $18, outside of the mention below. It's available in sizes XS to XL.
