Innovative Pack!

    This is a brand new pack from Mountainsmith. Coming in at about 42 Liters, it's a medium sized pack, but is capable of loads up to 35 lbs. I really like this pack. My favorite feature is Mountainsmith's "Breezeway" suspension system... it totally keeps the pack off your back, allowing air to flow through and cool your back while hiking. See my video review of this pack at:

    Is Waist-Belt removable?

    Is Waist-Belt removable?

    I know this is late for oats but In case others read this. The Phantom 40 does have a removable waist belt it attaches with heavy duty Velcro behind the breezeway panel.

    This is the reply I received from Mountainsmith

    to me


    Yes, the Phantom 40 has the same hip belt system as the Ghost 50. The hip belts can be completely removed. Let me know if you need any further assistance.
