Why We Like The Parsec Sleeping Bag

When we're meticulously packing for a rough hike to the top of Lone Peak to get a weekend of climbing in, we pack the Therm-a-rest Parsec 20 Degree Down Sleeping Bag. With the Parsec's slim design and ultralight weight, this is the perfect sleeping bag to pack when you already have to haul a rack, water, food, and your other climbing gear up the 12-mile trail. Constructed with ripstop polyester and hydrophobic down, this sleeping bag keeps warm on chillier fall nights and early spring evenings and dries quickly in condensated tents. The large footbox has an extra pocket of down to keep your toes extra warm on cold nights under the stars so by the time morning comes, you'll be well-rested and toasty, ready to get on the granite walls.


  • A sleek and small 20-degree down sleeping bag for going above and beyond
  • Hydrophobic down dries quickly and fends off dew
  • Durable polyester outer resists wear and tear
  • Packs down small for easy carry on big trips
  • Lightweight so you forget it's there on the hike in
  • Item #CAS00DM
