Built for Bigger Adventures — More Room, Same Performance

The Big Agnes Anthracite 20° Synthetic Sleeping Bag in Wide Long is designed for campers and backpackers who want genuine comfort without compromise. With an extended shoulder girth of 191cm and hip girth of 175cm, this bag gives plus-size sleepers the space to move freely — no more feeling pinched or restricted through the night.

Whether you're heading out on a summer backpacking trip or setting up camp in the back garden with the kids, the Anthracite 20 delivers reliable warmth, packability, and a PFAS-free water-repellent finish that keeps you dry without harmful chemicals.

Why the Wide Long Works for You

  • Generous fit — 191cm shoulder girth and 175cm hip girth for unrestricted movement
  • Rated to a limit of 20°F / -7°C — dependable warmth for three-season camping
  • FireLine™ Pro Eco Recycled Synthetic Insulation — high-loft, multi-denier fibres that trap heat efficiently and stay warm even if damp
  • PFAS-free water-repellent shell and lining — recycled polyester ripstop that sheds moisture without harmful chemicals
  • Contoured hood — follows the shape of your head for a comfortable, draught-free seal
  • Oversized no-draft collar and zipper — keeps cold air out where it matters most
  • 65" / 165cm YKK #5 anti-snag locking zipper — smooth, quick zip on the left side
  • Two-way zipper with Zipper Garage — ventilate easily without snagging
  • Low-profile cordlock — cinch or uncinch the hood with one hand
  • Interior liner loops — add a liner for extra warmth on colder nights (liner sold separately)
  • Exterior hang loops — for drying or long-term storage
  • Zip-together compatible — pairs with a Women's right-zip bag to share warmth
  • Stuff sack included
