Pros & cons

  • Kept Backpacker's testers 'mostly toasty' on freezing nights
  • Owner reviews praise how small and light it packs
  • Water-resistant DRILITE LOFT shell
  • Slim cut caused cold spots when side-sleeping, and testers felt chilly at about -1°C
  • Zip is not full length, which some owners dislike
