Hey Guys, Timbuk2 has a repair program where the interior TPU on the flap can be replaced for a flat fee of $25 including the return shipping back to you. Not exactly DIY, but it will get your bag up and running again, http://www.timbuk2.com/%2425-repair/9901-3-000.html Hope that helps, @timbuk2

Hey Justin, Because those sheathes are attached with great heat in ovens, it's not possible to reattach them. We do make a Day Pack puller that would replace them: http://www.timbuk2.com/day-pack-puller/9530-3-2001.html Hope that helps,
