I was very interested to try the Fireball, as it’s the lighterweight version of the Prism jacket, a mainstay in my and many other’s winter pack and a popular choice for Mountain Rescue teams. Warmth is provided by PrimaLoft Silver Eco, so good environmental credentials here and a solid performer too, with what felt like pretty equivalent warmth to its bigger sibling – enough for 3 seasons when at camp or belaying, but not too hot to keep on in certain winter conditions. The outer is Pertex Quantum, which is slippy and easy to pull on over or under other clothes, and sheds wind and water well. Sleeves and hood are elasticated, and the latter sits under a helmet well but lacks the facial protection of the aforementioned Prism jacket. The hem is drawcord, front zip is one way with a windguard, collar is fleecelined and handwarmer pockets are large and zipped. There are lighter, more breathable offerings in this test but I where I think the Fireball might win out is on durability. Montane’s insulated jackets just seem to go on forever. Weight 328g.
VERDICT: Durable all round insulation from the bike to the crag and the pub.
BEST FOR: Climbing and backpacking.
