The women's Osprey UNLTD AntiGravity 64 is a 64-litre trekking pack built around the proprietary AntiGravity suspension — tensioned mesh combined with aluminum stays that vents heat away from your back while keeping the load close to your body. Both the frame and hipbelt are shaped for a women's fit and fully adjustable to dial in the fit.
The main fabric, 210D high-tenacity nylon reinforced with UHMWPE fibers alongside a 500D recycled nylon, is built for abrasion resistance on rocky or brushy terrain. The pack carries two front pockets, two side pockets, two ice axe loops, and hydration-bladder compatibility, with access via both the top lid and a front panel J-zip. A rain cover is built in, so there's no separate piece to pack.
Osprey positions it for both classic multi-day trekking and lighter forms of thru-hiking, though at 2470 g (M/L) it leans toward a sturdier, more durable build rather than pure ultralight territory — a trade-off between carrying capacity and pack weight.
