Aircontact Lite 45+10 SL Backpack – Women's

Built for women tackling multi-day treks and loaded overnight trips, the Aircontact Lite 45+10 SL is our top pick for serious trail-bound athletes who need a pack that carries well under weight. The Aircontact Lite back system uses open-cell hollow-chamber foam to pump hot air out with every step, cutting perspiration and extending your range. The women's SL fit — shorter back length, narrower harness, conical hip belt — means this pack actually fits.

• Aircontact Lite back system uses open-cell hollow-chamber foam and an internal X-frame to move hot, humid air away from your back — proven to reduce perspiration by 15% on long hauls in tough conditions
• Women's SL construction includes a shorter adjustable torso length (14–19 in. via Vari-Quick system), narrower S-shaped shoulder harness, and a conical dual-density hip belt designed by women athletes for real anatomical fit
• Expandable 45+10L volume with a removable, height-adjustable lid and extendable collar lets you go lean for a day hike or pack out a full overnight without swapping bags
• Trail-ready organization includes a large front stretch pocket, side water bottle pockets, hip belt zippered pockets, ice tool and trekking pole loops, side compression straps, and hydration system compatibility
• Available in Maroon/Graphite; double-layer reinforced base and limited lifetime warranty back up the durability you need when this pack is your go-to for Southeast backcountry, weekend trips, and everything between
