Figure Four Tau-48
The τ-48 (Tau-48) Pack is the big brother of the τ-35 (Tau-35) Pack. At a mere 1 lb 7 oz stripped, it just may be the lightest ultralight alpine pack of its size. This pack is almost made exclusively out of Cubic Tech’s Cuben Fiber materials. If you need an ultralight alpine pack but your gear won’t fit in our τ-35 (Tau-35) Pack, the τ-48 (Tau-48) Pack is the choice for you.
