Grinder Hoody

  • Waterfowl : Marsh
(7 Reviews)

The Grinder Hoody was born to pull double-duty for waterfowl season. Worn between a next-to-skin layer and a shell for core insulation or as a breathable, water and abrasion-resistant outer layer. The Grinder has become the go-to high-performance intermediate layer for duck guides and is an integral piece in a waterfowlers system.

    Why We Made This

    Waterfowl season is a grind and hunters have been looking for a durable lighter-weight insulation piece to get them through the season. They needed a jacket that could pull double duty: from dynamic workloads of getting to the field and setting up decoys to transitioning to insulation for periods of static activity in the blind. Our approach was to use the combination of lofted fleece for the interior to deliver core-warmth and superior abrasion-resistance technology on the exterior for ultimate durability. A DWR finish provides water-resistance from light precipitation that won’t wet-out the face fabric and the hood form-fits to your head for added warmth, concealment and protection from the elements without hampering your field of vision.

    This hoody is a special piece. I have had it for about 2 months now during the early months of waterfowl in Minnesota. I love Sitka gear and plan to add the gradient jacket and delta wading jacket to finish out my system. I already have the core mid zip undershirt. I walked dykes on rice paddies for 4 1/2 miles today and was never hot, it cools so well. This piece really has so many different uses, I really like to jump ponds and walk dykes and this piece has been a dream come true for me. Holds up well in light rain which is all I’ve had. My favorite hunting hoody out of all the ones I own!

    OK, what a wonderful surprise is this piece of “gear”. It looked interesting in the picture, but I’d never have guessed how functional it would be. Of course I find this phenomenon to be true of a lot of Sitka products. You really don’t know how great they are til you use them. But this “mid layer” was on me every waterfowl hunt of the 2019/2020 season. And I am in the hunting business… in the field a lot! I was amazed at the hood itself. I own and hunt on lands along the North Platte River in Western Nebraska. My usual deal was to everyday wear a fleece balaclava of another brand. That would always keep my neck warm and on the cold days (which we can really have), I would pull it up over a baseball style cap to keep my ears warm. Been doing this for year! So when trying a full Sitka system out, I first bought their core lightweight balaclava, but used it only once. Nothing against that piece (though it should be cut a lot bigger), but once I started pulling up the hood of the Grinder, I never went back. And I still thought, “Someday, it’s going to be truly cold and too much for this hood”. But it never was. Mind you, we didn’t have much in the way of blizzard hunting (my favorite) this year. But if the wind and cold is too much, nothing the hood of my Delta Wading, or Hudson Jacket pulled up over the Grinder won’t handle! The Grinder Hoody is so good, so comfortable, and clearly makes me look so cool (Ha!), that I gave one to one of my guides for Xmas, and I haven’t seen him without it on since… hunting or not! I bought a second one and put it into storage in case they ever discontinue it... but i doubt they will!

    Love this top as it sheds light rain and moist air conditions great without getting hot while exerting energy early setting decoys, walking to a spot or in and out at the boat ramp. Only thing I would change is they need to add a kangaroo pocket. It’s annoying when you’re done for the day and wearing it around and you go to put your hands or keys/wallet there and nothing but slick sides. Add a simple kangaroo Sitka it’s a feature that needs to be there on a hoody.

    WORTH IT! I wore this hoody in Northwest Nebraska for a January duck/goose hunt. when putting out decoys in 20 to 30 mph winds while it was 20degrees out was no problem having a merino wool shirt under and Dakota vest over this. i only put my jacket (dakota hoody) on when i was sitting still during the hunt. the outer material did great in wind and snow keeping me warm and dry. every duck hunter should have this. only reason for not giving a 5 start is no kangaroo pocket.

    Fit, fabric, and finish are all great, plus it's the perfect weight for layering late season or solo early and mid season. However, IT ONLY HAS ONE CHEST POCKET, no side pockets or kangaroo pocket on the front, unlike every other hoody I've ever owned. C'mon Sitka, that's an obvious inclusion on a $170 garment that pulls double duty.

    The grinder hoody is a amazing layering piece. Great for Under a vest or waterproof jacket. Very warm and great for early-mid season conditions.

    This might be my favorite piece of clothing. I wear way too often because its about the perfect heavy sweatshirt type of garment. Super comfortable. The DWR is awesome when using it as out lighter outer layer and the dog splashes water on me setting up decoys.
