Product Summary / Girth and Size

  • Traditionally insulated bags designed without the integrated pad sleeve (found on Big Agnes System bags)
  • bluesign® certified insulation material
  • Pinneco Core® synthetic insulation , insulation technology made from short-stapled fiber insulation layers. Features CoreScreen™, a breathable membrane. This membrane is laminated onto insulation layers through a patented process called CoreFusion™. The CoreScreen™ membrane works as virtual air pump, actively drawing moisture away while retaining warmth within. This membrane-fused insulation utilizes body movements to compress the insulation system and push moisture through the breathable membrane.
  • Insotect Tubic™ Vertical Baffle Construction combines the presence of Vertical Thermal Channel™ (VTC) and Insotect’s proprietary DualVault™ system component, alongside with the Pinneco Core® technology, into one complete insulation system. The tubular-shaped channels allows for the vertical and arched insulation fibers to deliver its maximum loft. Air is better trapped and weight is better decreased.
