About this item

  • Comes with an Osprey Hydraulics LT 2.5 L reservoir with direct zip access and sternum strap magnetic bite valve attachment.
  • A rolled, soft-edged harness creates a comfortable and stable carry.
  • Offers traditional LidLock helmet carry or full face helmet carry with the compression straps.
  • Just the right volume for any ride, providing tool organization, helmet carry and a full U-zip main compartment opening.
  • Upper side compression and full face helmet carry


When you're riding, you don't want to think about your pack-and the women's Sylva 5-liter pack's streamlined profile ensures that you won't. With an included updated Hydraulics LT 2.5-liter reservoir, ventilated AirSpeed™ suspension and included raincover, this low-volume, minimal bike pack is the perfect option for desert heat or humid climates where you need nothing more than hydration and a few essentials.
