Using Thermium would increase the weather resistance by taping the seams, which would boost performance for most winter activities. We love Windstopper! Unlike the other Windstopper jackets tested here, the Heat Treat will not be updated for fall 2016 with a Gore Thermium membrane.

Note how the hood doesn’t close completely around the face. Max in the Black Diamond Heat Treat Hoody, Escalante, UT. Luc removed this jacket from consideration based on this reason alone. As we mentioned earlier, the hood is ineffective at sealing the face area. We don’t recommend this jacket for overnight trips or activities that benefit from a high warmth to weight ratio. The vast majority of the Heat Treat’s weight comes from the fabric. Max used this for a five-day January backpacking trip in Utah canyon country (temperatures in the upper teens) and would have been happier with a warmer jacket. Performance Evaluation of the Black Diamond Heat Treat Hoody Review Warmth

The $300 Patagonia DAS is our favorite synthetic insulated parka. The Heat Treat’s main competitor is the $400 Arcteryx Kappa Hoody, which uses even more durable 70D and 80D Windstopper fabrics, has more insulation, and better features such as a four-point adjustable hood, a chest pocket, and two larger drop-in stash pockets. Though the Heat Treat’s zipper didn’t break during our test period, and one person in BD’s warranty department said they don’t see this often, we wish BD would use standard issue, tough zippers. This bothered Max when he first used BD apparel in summer 2013, but it wasn’t until winter 2014 that his Stance Belay Parka zipper broke (by the neck, where the zipper curves). We have two other small complaints about its design: (1) the hood’s ineffective closure lets in lots of cold air around the sides of the face and (2) in order to provide a unique look, the main zipper’s interlocking area is half that of standard parka zippers. Due to the lower warmth to weight ratio, the jacket is better suited to resort skiing than lightweight climbing and backcountry applications. It is a midweight winter parka with a durable fabric. The Heat Treat is an all-purpose winter jacket for around town and some winter sports. At 25-50% off, it could be a very good buy for an all-purpose winter insulated jacket. UPDATE: As of March 2018, this jacket can be found in inventory and on sale up to 50% off at Amazon, Moosejaw, and Outdoor Gear Exchange.

In addition, we hope the information provided here is useful in the context of today’s broad offering of synthetic insulated jackets. We’ve left our original review unchanged below in case you find this jacket on sale.
