The Alpha Direct 4004 Hoodie is an ultralight hoodie built with Polartec Alpha Direct 4004 fabric. Alpha Direct 4004 is the 90gsm variant. This is an excellent intense activity insulation layer that should be paired with a shell for a very light, modular system. The structure of the fabric is very open, with fluffy tufts between. With a shell to cap the air, the tufts create loft and the spaces create dead air. It keeps you very warm for it’s weight. Without a shell Alpha has very little insulation value, which is one of it’s benefits. By venting the outer shell and exposing the Alpha directly to the air, you can dump a lot of heat quickly without the need for inner layer zippers. You can change the outer shell to deal with different conditions while providing a huge and highly adjustable range of insulation. This can’t compare to a true static insulator like a down sweater at camp but it can sometimes be enough to get by with, while covering a giant range of conditions while active.

Approximately 5oz (small).

    Though I worry a bit about the somewhat fragile nature of Polartec Alpha, this piece is great. I don’t really wear it while hiking because I’m afraid it will snag. I may press it into service in colder conditions underneath a wind jacket or puffy. I wear it at camp and to sleep in. It is quite warm for its weight and very soft. The hood is great when paired with a beanie of similar material and in warmer temps when I don’t use the Waterbear Balaclava, the hood provides a soft layer between the stubble on my face from not shaving and the material of my pillow. I own quite a few Timmermade pieces and they individually, and combined, have really brought the weight of my pack down during the colder months. If you are carrying around a heavier hoodie or sweatshirt, do yourself a favor and ditch it for one of these.

    Worth the wait/weight.

    Got this a few days ago in the mail and tested it out that night in the backyard hammock. The idea being, if slept in, I can get by with a lighter quilt, and no hoodie(down to 40f).
    I was using a 50° quilt/underquilt and the Temp dropped to ~40°f. Worked like a charm; I never woke up cold.(which had been a problem in the past unless I wore a hoodie to bed)
    With rain gear that can act as a shell, I will be hiking without a hoodie and a few oz off the quilt until the temp goes below 40°.

    So far, so good.
