John says

The Alpkit Ultra 120 is not just another sleeping bag; it is a testament to minimalist design and efficiency. It offers excellent value, providing top-tier PrimaLoft Gold insulation known for its superior warmth-to-weight ratio.

It’s a fine example of the adage that you get what you pay for: your £200 gets you PrimaLoft Gold insulation, one of the best warmth-to-weight ratio synthetic fills on the market. That – and the fact that every other feature is minimal in nature – makes this bag truly lightweight and ensures it occupies very little space in your pack.

The bag's construction is optimised for weight savings, evidenced by a shortened zip that reduces overall bulk and weight. However, this feature may limit its versatility as a blanket on colder nights, suggesting a trade-off between weight and comfort.

The bag is suitable for warmer conditions or quick trips where a light pack is essential. Despite its tight fit, it offers adequate comfort once the insulation warms up, which may take a few minutes after settling in.
