Arc'teryx Aptin Zip Hoody
Arc'teryx designed the Aptin Zip Hoody specifically for cold-weather running, combining Polartec Power Dry midweight fleece with an Akrose woven polyester overlay on the chest and arms. Weighing 250 grams (8.8 oz), this discontinued pullover features a 3/4-length front zip, low-profile hood, and thumbhole cuffs. The grid-backed fleece (84% polyester, 16% elastane) provides thermal efficiency while the DWR-treated overlay adds wind and weather protection. Trim fit designed for high-output activities. The original retail price was approximately $150.
Hybrid Fleece and Overlay Construction
The hybrid construction sets this apart from standard running layers. The smooth-faced Polartec Power Dry fleece with grid backing on the torso manages moisture exceptionally well during high-output efforts. At the same time, the Akrose woven polyester overlay on the chest and arms blocks wind where you need protection most. This combination creates a piece that's unlike any other layer I've owned. Some sections are almost sheer and transparent, which looks unusual but enables incredible breathability. The result is a running layer that keeps you warm without cooking you on climbs.
How Does the Arc'teryx Aptin Zip Hoody Fit?
The trim fit works well for running, with no excess fabric flapping. At just over 6 feet and 165 pounds, I wear a large size that allows a thin base layer underneath, but nothing heavier. The gusseted underarms and articulated patterning provide unrestricted movement for arm swing during runs. The low-profile hood fits close to my head without obstructing peripheral vision, and the semi-auto-locking zipper stays in place once adjusted. Thumbhole cuffs keep sleeves from riding up during movement, though I rarely use them since I prefer my hands free.
Best Between 25 and 45 Degrees
For temperatures between 25 and 45 degrees during high-output activity, yes. The 3/4-length zip allows rapid venting when effort increases, and the grid-backed fleece manages moisture well enough to prevent the clammy, chilled feeling that develops when sweat-soaked layers cool down. I've run through Texas winters with this as my outer layer in the 30s and stayed comfortable. For colder conditions or lower-output activities, the Aptin works better as a midlayer under a shell like the Incendo Hoody or Gamma SL Hoody.
Arc'teryx Aptin Zip Hoody vs. Similar Running Layers
The Centre Hoody uses Pontetorto Hardface fleece with better wind resistance but less breathability. The Caliber Zip Neck lacks a hood but offers similar warmth with Polartec Classic Micro Velour Cord fleece. The Patagonia R1 Air Full-Zip Hoody at $199 provides comparable breathable warmth with different styling. Within Arc'teryx's discontinued running lineup, the Aptin occupied a unique position between pure fleece layers and wind-blocking shells.
Resale Value and Current Alternatives
For runners who train through winter and want a versatile hybrid layer, the discontinued Aptin delivers excellent performance. Resale prices typically range from $60 to $120, depending on condition and colorway. The unique construction combining grid fleece with protective overlays isn't replicated in Arc'teryx's current lineup. For similar functionality with current availability, consider the Cormac Hoody for pure running use or the Delta AR (also discontinued) for more substantial fleece warmth. Check Arc'teryx for current midlayer options.
