Overview

Built for cold-weather layering, this full-zip puffy jacket is designed to bridge the gap between a hooded sweatshirt and a heavy insulated outer layer. It uses 800 gsm synthetic fill, a woven nylon outer shell, and a hooded profile to deliver a practical option for hunting, hiking, and everyday wear when temperatures drop. Sherpa fleece-lined hand pockets, a zippered internal chest pocket, internal ribbing at the sleeve cuffs, and dipped drawcords add useful cold-weather details without overcomplicating the design. It is a straightforward choice for serious outdoor use, though its bulk and warmth make it more suited to cold conditions than mild-weather wear.

Specifications

ColorBlack
Long DescriptionThe Grinnell Jacket is not like the puffy jacket that has been done time after time, it’s where your favorite full-zip hoody meets the warmest down jacket you’ve ever worn. The jacket is literally named after a glacier in the heart of Glacier National Park, we did that for a reason. Similar to the Oberlin Pullover Puffy in design, this time we added a full-zipper so it comes on and off just like your traditional jacket but with the same profile and hood that the Oberlin had and all the same features. We packed this puffy jacket with 800 gsm synthetic fill because when temperatures drop, and we mean it, this thing is a furnace. The two hand pockets are lined with ultra warm sherpa fleece for cold hands. Internal ribbing at the sleeve cuffs seals out the cold. Dipped drawcords. Custom MKC PVC patches and printed liner throughout. The Grinnell Puffy Zip Jacket is truly what you want for your cold-weather daily jacket. Whether it’s your go-to hunting jacket or your everyday hiking jacket, the Grinnell handles it. Standing around a bonfire. School drop-off. Dog walks. Running errands. Built for everyone. Built to last. Your new favorite jacket.

Pros

  • Full-zip design makes it easy to layer and take on or off quickly.
  • 800 gsm synthetic fill provides substantial warmth for cold-weather use.

Considerations & Trade-offs

  • Full-zip design makes it easier to put on and take off than a pullover, but it also changes the fit and feel compared with the Oberlin-style profile it shares.
  • The jacket is built around heavy cold-weather insulation, so it is aimed at low-temperature use rather than mild-weather versatility.
  • Sherpa fleece-lined hand pockets add warmth, but the pocket zippers mean they are not as open-access as simple handwarmer pockets.
  • Made from globally sourced materials, which may matter to buyers looking for a fully domestic sourcing story.
