At Hotcore, we believe in the humane and respectful treatment of animals, including the geese and ducks that provide down and feathers. We use high quality down insulation because it is the absolute best insulator, with unmatched warmth-to-weight and durability characteristics.

Our supply chain is third-party audited and Certified, ensuring the down used in our products is ethically sourced. You can be confident that the product you are enjoying was made with high standards of animal welfare in mind.

High quality TrueLoft™ micro fibre synthetic insulation traps more warm air between its fibers than traditional insulations with the same loft. This gives you a warm, soft sleeping bag in a compact and lightweight size.

  • Lightweight – some of the lightest weight insulation available
  • Compressible – siliconized fibres slide easily allowing for greater loft, compressibility, and softness
  • Breathable – insulation and fabrics breathe to allow heat-robbing moisture & humidity to escape
  • Extremely quick drying – hydrophobic qualities allow TrueLoft™ to absorb less water and dry quickly
  • Warm when wet – while drying, TrueLoft™ still keeps you warm, performing better than inferior insulations
