A lightweight, high-performance down sleeping bag designed for fast and light summer use
Vango says:
When you're exploring your limits you need your kit to perform. The Force Ten Ultra 150 has been designed to support your biggest adventures with our best technology packed into a compact size for ultra packability. With our best warmth to weight ratio, the Ultra 150 helps reduce the weight you need to carry without sacrificing on comfort or performance.
A lightweight yet durable nylon shell fabric reduces pack size and weight thanks to its highly compressible properties. Strategically placed ARC (Advanced Reflective Coating) layers reflect heat back to your body to keep you warm as temperatures plummet. 150 grams of our highest fill power goose down works to keep you warm in all conditions whilst a hydro barrier coating keeps performance 4x longer than traditional down if it gets wet.
Our Verdict
The F10 Ultra 150 uses 1000-fill-power goose down with a 150g fill to deliver an efficient balance of warmth and packability, weighing 549g. This is a notably high fill power for this category, and it translates into strong loft and a compact packed size while maintaining usable insulation for warm-weather trips. The comfort limit of around 2°C feels realistic when paired with an appropriate mat, though it is clearly aimed at high summer and settled conditions rather than extended shoulder-season use.
The mummy cut is shaped for efficiency, with a relatively trim profile that helps retain heat while keeping weight down. Despite the focus on weight, it has not been stripped back excessively. The twin 1/4-length zips add a useful level of function, allowing arm movement and ventilation without fully opening the bag.
The lightweight 10D fabric contributes to its low weight and compact pack size, though it benefits from careful use over time. The hydrophobic down treatment adds some reassurance in damp conditions, helping the insulation maintain loft more effectively than untreated down. Overall, this is a well-considered option that balances low weight with practical usability, and it would be good to see more from this range of bags, pushing into lower temperatures.
