The Aegismax MLT5 is a sleeping bag liner similar to the Sea to Summit Thermolite Reactor.

Both have a mummy shape, and both use lightweight and breathable Thermolite material that adds ~2-5C to your sleeping bag rating.

Specifications
  • Material: Thermolite (likely 80g/m²)
  • Dimensions: 210 x 83 x 38cm
  • Packed: 8 x 12cm diameter roll
  • Weight: 262g
  • Colour: black

As comparison, the S2S Thermolite Reactor:
  • Uses similar material
  • Is the same length (210cm)
  • Is 7cm wider (90 vs 83cm)   
  • Is 14g lighter (248 vs 262g)
  • Has a sewn footbox 
  • Has a cinching drawcord and red trim around the hood
  • Is substantially more expensive (~ $55 vs $29.40 USD)

Pros
  • Thermolite material is breathable, soft, stretchy and comfortable
  • Washing your liner on long treks helps minimize smells
  • Also use as a sheet on hotel/hostel beds, or as a blanket on airplanes
  • Also available in shorter and rectangular bag versions, and in a thicker orange version
  • Can be machine washed 

Cons
  • Extra weight and bulk in your pack
  • Lacks some features of the S2S bags
    • No footbox - might feel constricting 
    • No cinching cord to secure the hood close to your head
  • Thermolite won't protect much against wind or insects, or boost warmth inside a sleeping bag by a large amount (despite S2S claims)
  • A warmer sleeping bag is probably better from a weight ratio perspective
  • Not recommended to use alone unless conditions are very warm
  • Silk is more effective as a liner material (but is expensive and difficult to clean)
  • Black colour appears more grey than black
