How big is Fairfax?

Yeap! You wonder how big is CamelbaK's Fairfax '09?

Well, according to camelbak info:

• 14.90€
• Cargo: 2.25L
• Dimensions: 39.0cm x 23.0cm x 9.0cm
• Weight: .45kg empty & 1.89kg filled
• 50 oz / 1.5 L OMEGA™ HydroTanium™ Reservoir with Lifetime Warranty
• 3 colors: black-hi-viz / estate-blue-charcoal / racing-red-charcoal
• Extras:
  • Insulated reservoir pocket keeps liquid cool for hours
  • Air Mesh channeled back panel and shoulder straps for enhanced ventilation
  • External zip pocket for keys and essentials
  • Front and back reflectivity improves low-light visibility

Somehow Fairfax ain't that big, actually is more like 2.25 L_total - 1.5 L_h2o = 0.75 L_{useful cargo}.

Let me demonstrate by using a measure plastic cup:
I still didn't manage to fit a pump. Perhaps I should injected or stitch it with velcro outside Fairfax. (*_*)


P.S. - I believe Fairfax are small cities in USA but in Portugal, if Berg Cycles wants to name one of it's small hydration bags, the smallest cities are Alcoutim, Mértola e Idanha-a-Nova. Maybe Corvo from Açores is the smallest.
