Katiewrote a review of Timbuk2 Tandem Pannier on November 21, 2017
Familiarity: I've used it several times
My partner has used the Tandem for about 6 months on his hour long commute to work. It's super easy to take on and off his rack with the velcro strips and even when it's been raining his gear has stayed dry. He loves the zipper pocket on the outside that he can use to put his phone in for easy access. Added bonus, it looks pretty slick!
