Whether you've realized your old pack doesn't fit anymore or you are looking to invest in your first one, the Deuter Women's ACT Trail 20 SL Backpack is your ideal single- to multi-day pack. Its compact design features a women-specific shape to keep your load close and unique mesh back panels to ensure you stay as comfortable as possible no matter where the trail, ice, or rocks lead you.

  • Slim Line (SL) is a women-specific design that features narrower and shorter spaces between straps (both vertically and horizontally), S-shaped shoulder straps, and a curved hip-belt for maximum comfort
  • Aircontact Trail System features two breathable foam pads that 'pump' with an air channel between them to push air up and out while you hike
  • AirMesh lining on the back panel and mesh wings on the hip-belt offer maximum breathability where the pack makes the most contact with your back
  • Delrin U-shaped frame adds a rigid structure to the pack so it doesn't buckle during climbs or approaches
  • Front panel access allows you to find things easily without unloading the pack
  • Internal wet laundry compartment separates soaked clothes from fresh layers
  • Rain cover deploys from bottom pocket to protect your load from torrential rains
  • Front mesh pocket holds a helmet or rain shell
  • Compression straps cinch down pack and help attach your gear to the outside of the pack

Wife Loves it.

  • Familiarity:I've used it several times

I bought this as a gift for the wife. Its her first pack. She loves it.

Can someone tell me what size this pack...

Can someone tell me what size this pack measures?
I know its listed as one size but I would like to know the exact measurement...

Best Answer

Measurements are 22" x 9.8" x 7.9" (H x W x D). Deuter does not list the size. I suggest using the chat feature on Backcountry's website. The rep may be willing to measure it for you and email you back later.
