Arc’teryx’s Delta Jacket is an ultralight fleece product of Octa Fleece, one of many newer, high-tech fleeces to hit the market previously couple of years. The identify comes from the octopus-like weaving which creates air gaps, which assist lure heat whereas additionally permitting moisture to flee. It is very talked-about with cottage trade ultralight manufacturers, however Arc’teryx adopted it for the 2025 revamp of the corporate’s well-liked Delta fleece jacket.
I hesitated to place this jacket on this information as a result of, whereas I prefer it as an ultralight mid layer for summer season journeys, there may be an older, heavier model of the Delta jacket. Judging by the offended critiques on Arc’teryx’s web site, it was very talked-about. This jacket is one thing else solely, however disgruntled followers of the older model apart, this can be a nice mid layer for summer season journeys, particularly when paired with a solar shirt hoodie. At 8.5 oz for this, and 6 oz for a solar hoodie just like the one from Kuiu under, you’ve got a combo that enables a number of layering choices and nonetheless weighs lower than many extra well-liked grid fleece choices. My solely gripe is that style was, um, not considered within the design of this jacket. One person overview on the Arc’teryx web site likens it to Mr. Roger’s sweater, which is about proper. However hey, it is mild, it is practical—who cares about style within the backcountry?
