Engineered for the Mission. Designed for the Wild.

The Spartan Odyssey is a tactical, performance-oriented synthetic sleeping bag designed for endurance and comfort. Whether you’re deployed in the field, trekking through the bush, or chasing game through the high country, the Spartan Odyssey delivers uncompromising performance in harsh Australian conditions. This sleeping bag is purpose-built for military personnel, hunters, and serious outdoor adventurers, striking the balance between the rugged functionality required for tactical missions, thermal efficiency and comfort.

The design team combined their experience designing military-grade equipment and love for outdoor gear, aplying that expertise to reinvent the ‘military-grade’ sleeping bag—transforming it from a simple sleep system into a versatile, functional tool for both tactical field and recreational outdoor use.

Key Features:

• Mission-Ready Construction
  Crafted with a durable 20D Nylon shell and lining treated with a DWR finish, the Spartan Odyssey is built to endure. The 70D Nylon footbox lining allows combat boots to be worn inside, essential for rapid response.
• Certified ISO 23537-1:2022 Rated
  The Spartan Odyssey is certified ISO 23537-1:2022 rated to ensure accurate temperature ratings, allowing you to choose the right gear for your mission.  
• Adaptable Warmth
  Engineered with Thermolite insulated filling and Thermolite T-Down baffles, the bag will keep you toasty at night without weighing down your pack during the day. It features horizontal baffles to stabilise the distribution of the insulation and reduce cold spots, and baffled draft tubes covering the zip sliders to seal in body heat, preventing warmth from escaping. The Spartan Odysseys’ hood is equipped with a draught collar and draught tubes around the neck and face to reduce open space between the sleeping bag and neck, minimising the cold getting in, and any warm air escaping, a crucial feature for chilly nights.
• Optimised Design for Tactical Use
  Integrated armholes are strategically positioned to allow functional mobility— allowing easy access to operate equipment, take orders, brew a coffee or move to picket, all without reducing your core temperature. A hook at the foot of the bag connects to an internal mid-length loop, allowing you to shorten the bag and walk when movement is required, stay prepared and stay alert for the enemy without leaving your sleeping bag.
• Quick Deploy and Walk Mode
  A two-way YKK #5 centre zip with an Anti-Snag Zipper offers reliable performance and fast access. The anti-snag zippers with silent, double-sided pull tabs make getting in and out a breeze, even with gloves.
• Stowaway Pocket Easily stow your phone, batteries, head torches or power banks in the internal pocket to keep them warm and reduce battery discharge from the cold.

Standardised Laboratory Rating Range:
Standardised laboratory tests produce a rating range for each sleeping bag, with two temperature ratings within that range specifically mentioned:

Comfort rating indicates the temperature at which a cold sleeper might feel comfortable. This is the temperature rating brands use on women's bags. If you are a female, you would use the Comfort temperature rating.

Lower Limit rating (which is always lower than the comfort rating) indicates the temperature at which a warm sleeper might still feel comfortable. This is the temperature rating brands use on men's bags. If you are male, you would use Lower Limit temperature rating.
