Most manufacturers target two weight points for an insulated ultralight jacket: around 8 to 12 oz for a lightweight jacket, and around 25+ oz for a belay-style parka. There are only a few jackets between those weights, such as the Patagonia Micro Puff Jacket at 16.5 oz with 2.7 oz/yd2 Polarguard Delta, and Wild Things hooded EP Jacket with Primaloft insulation.
OR jumps into the fray with the Zero, a 20-oz jacket (size large – a medium could be around 18 oz to 19 oz). The Zero uses 4.0 oz/yd2 Primaloft One insulation in the torso, 3.0 oz/yd2 in the sleeves, and 1.8 oz/yd2 in the hood – intelligently placing the most warmth at the torso. The light hood insulation assumes that one is already wearing a hat, balaclava, or helmet. OR knows about climbing. The hood is large enough to cover a climbing helmet.
The Zero weighs less than a 25+ oz belay parka but may come close to the same warmth. Best of all, the jacket retails for a reasonable $169.
