Let’s face it: unless you’re camping, pass the age of twenty-two the old two strap, schoolboy backpack is downright unacceptable. Once you’ve graduated it’s time to upgrade. Pendleton has released a 21.5 -inch leather plaid weekender duffle bag to replace that shabby sack you keep laying around for quick trips to the coast — it has the same quick fix, throw-it-in, run-out-the-door qualities you loved in that old backpack combined with a masculine style that mixes Pendleton’s famed plaid wool with a rich leather. Upgrade to Pendleton’s Leather Plaid Weekender for $278.
