Warmth with little penalty
- Familiarity: I've put it through the wringer
- Fit: True to size
The Fireball is probably most comparable to Patagonia's Nano pullover. But while The Nano uses 60-g Primaloft, the Fireball uses 40-g. This reduces the Fireball's weight by about an ounce. The fit is also a little more athletic, so there is less void between you and the garment to heat. It also allows it to fit well under a slim running jacket.
Like the Slipstream GL Smock, it has a double zipper, which I still don't get--again, perhaps to help cool the torso while insulating the neck or for you iPod. But I haven't used it.
I used it on the first known rim to rim to rim run of Hells canyon as my emergency bivy. It provided enough warmth so that I could sleep relatively well.
For what it is, minimalist synthetic adventure race insulation, it works great. But don't expect it to keep you warm below 45. For that, look at the Flux, Prism, or down insulation.
