Gym clothes and work stuff have always kept an uneasy peace---they can sometimes grudgingly occupy space in the same backpack, but if you're not careful, stinky madness ensues.
Along comes Aer to broker a lasting accord. Originally funded through Kickstarter, this thoughtfully designed duffel-style backpack is now available to the general public---and it's a revelation. No more making due with a cavernous rucksack-style bag and its a sad kludged-on laptop sleeve. The Aer incorporates a dedicated (and ventilated) shoe compartment, a spacious front-zip main space for clothes and a towel, dual multi-pocketed side panels, and a separate padded space for your computer. It's light enough to wear on a hard pre-work training ride, yet durable enough to scrunch under a bus seat or in a gym locker without tearing. And after a full day at the office, your MacBook won't reek of chamois cream.
