If the Swiss Army issued a chalk bag, this'd be it. It comes with an external zippered pocket for keys or an emergency headlamp. And a belt attachment that doubles as a bottle opener (for those too pumped for twist off).

• Invista Superpack nylon, and schoeller®-dynamic 40-denier nylon fleece make the bag both supple and tough.
• Drawcord closure cinches easily to prevent spillage during transport.
• Brush holder.
• Injection-moulded belt attachment allows chalkbag to slide easily for dipping. And doubles as your bottle opener.
• Waist belt included.
• External zippered pocket.
