The Helly Hansen Odin Everdown Hooded Jacket has been tested for warmth, weather resistance, and packability in the mountains.
According to the test, it is similar to synthetic insulated jackets like the Rab Xenon and the Keela Solo, but filled with down, making it lighter, more breathable, and warmer.
The test included stormy sessions in the mountains and a campout on Carnedd Llewelyn, where it performed well in freezing conditions.
The jacket has a snug fit and an impressive warmth-to-weight ratio, but has a short cut at the hem, which may not be suitable for everyone.
