Like the Rab Xenon X, the Alpkit Katabatic uses 60g/m² PrimaLoft Gold Active, which is the most breathable of the PrimaLoft insulation family, ideal for use on the move. It’s a little heavier at 355g for a size 10 (I love the honest way that Alpkit puts the weights for each size on their website). The increased weight brings a slightly more rugged feeling, stylish matt fabrics, and a brushed fleece chin guard. It’s also less expensive, so what’s not to like?
VERDICT: Good active insulation for cold wet days on the hill.
BEST FOR: Adventures in all weathers.
