Use of the new Pertex 10 denier Quantum fabric ensures that the Rab Infinity is very light indeed. At 484g it is not the lightest jacket, but it provides more insulation, so it is usable at lower temperatures. It uses top-quality down too, which keeps the weight down further. The Infinity hood surprisingly comes without any volume adjuster or drawcords, so it either fits or it does not, and for me it did not fit as well as it could have. Some brushed polyester around the chin area adds welcome comfort too. The cut of the sleeves was particular good as they fitted perfectly, allowing me to raise my arms without the hem of the jacket or the sleeves riding up. Use this for spring and autumn camping, and its low weight would be a real benefit, while in winter it should be okay except in the coldest of conditions. But the Rab Infinity’s hood was very frustrating as I just wanted a closer fit, but it has no drawcords. Others may prefer a removable hood, particularly as this one may not actually fit that well without an additional hat inside. Like other lightweight duvets, it is not quite as warm as the warmest; and the new 10D Pertex Quantum does feel a little delicate.

The Rab Infinity is great if the hood fits you better than it did me, as this is a very lightweight duvet that offers good insulation for milder winter conditions.
