The Mountain Hardwear Blazar pullover weighs 0.2 ounces less than the Gram Comp (that’s the equivalent of two United States pennies) and is therefore the lightest three-layer waterproof breathable jacket on the planet. We’re in the process of testing both jackets head-to-head in the field. Our initial impression is that the Gram Comp Pull may be the best lightweight waterproof shell on the planet. Although we cannot yet confidently comment on many performance aspects the Gram Comp Pull has one significant advantage over all other superlight three-layer shells we’ve tested: it’s the only jacket with an external chest pocket. Our testers love this feature because it provides easy access to a camera, an energy bar, map, and other useful small objects that ones needs to be readily accessible.
This is a world-class jacket that pushes the boundaries on fast and light adventures of all kinds. It’s so lightweight and so breathable that it crosses into territories traditionally occupied by windshells and softshells. The three-layer construction and Gore Active membrane also makes it far more breathable and more comfortable than many two or 2.5 layer rain jackets that weigh slightly less. We’ve very impressed with this jacket so far.
The main question we are asking in our tests is: do the benefits resulting from the 3 oz weight savings from the Arcteryx Alpha FL exceed the costs of reduced durability, a non helmet compatible hood, fewer adjustment cords, and a smaller chest pocket?
