Filson - Dryden Leather-Trimmed Nylon Briefcase

If you often go straight to the gym from work, you'll find Filson's 'Dryden' briefcase a robust and reliable option. It's cut from ballistic nylon, a material first developed for WWII servicemen, and trimmed with vegetable-tanned bridle leather straps and handles. Unzip it and you'll find a host of pockets for keeping smaller items and your laptop safe.
