HyperDown Jacket Reviews

Hyperdown jacket

Seems like a great purchase. Very light and seems very warm.

hyper down jacket

Great Jacket, Fits good and true to size. gonna put it through the ringer this season but will be an essential item I bring all season. will report back if any negative feedback but for now it seems great and fits great.

Ready for the cold !

Bought the jacket for a January elk hunt when temps will be below zero by that time of the year. Jacket fits perfect and allows for great range of motion.

HyperDown

I just got the jacket a few weeks ago. Haven’t had the chance to use it in filled yet but will be this fall. Jacket is a bit big which I like for layering. Overall seems awesome.

Takes the chill out of glassing.

The Sitka HyperDown Jacket completes the system when you need that warm outer puffy layer. The weight to warmth ratio on this piece is nice. You can throw it in your pack, climb to your vantage point, and pull it out and put it on to stay warm while you glass.

Concept great, implementation needs revision

The hood is unusable with the lack of a middle drawstring. Using the pocket for compressed storage of the jacket, the pocket\zipper didn't hold up. Just sent mine in for return/refund. The concept of a larger size jacket that fits over everything else, and that has the most insulation they sell sounded great. I am hoping a new revision is released addressing my concerns.

Nice jacket, but some big misses

Got hands on new Kelvin Hyperdown Jacket. Initial impressions compared against the predecessor Kelvin Down WS Hoody: 1) it is way lighter, definitely backpacking friendly. However I question the durability of the shell (27d), feels noticeably more delicate and tear prone than the Kelvin Down WS 2) longer length cut is awesome as is the solid colorway 3) feels warm, but not as lofty as the Down WS 4) Does NOT have Gore Windstopper, which is a big miss in my book. Part of the reason for the less sturdy face fabric is to achieve it's lighter weight I suppose, but if you're glassing exposed ridges in this in high winds, would probably wish it had it. 5) Hood is poorly constructed. No drawstring adjustment on the back of the hood to cinch in, just along the outside, which makes peripheral vision when head turning horrible. 6) internal dump pockets are nice improvement over the old zip pockets, which were not ideal for large glassing mitts. Overall, same oversized fit, but more proportional now with the longer cut. A decent jacket, but part of me wishes I hadn't parted with my old Kelvin Down WS as this just doesn't have the same bombproof feel that would hold up to hunting. Doesn't even say anywhere that the shell was even DWR treated... Nice to have a solid color option now for daily use in Minnesota winters too.

The warmest puffy jacket SITKA’s ever made!

The warmest puffy jacket (and pants) SITKA’s ever made! Coldest hunt I used it on was a 10-day winter mountain goat hunt in BC. Temps dropped down to -10F but with the jacket/pants on I was super comfortable. My buddies called me the 'Michelin Man' because I was so puffy. They were jealous... and cold...

Game changer for late season mountain hunts

The HyperDown Jacket is a game changer for late season mountain hunts, when you need as much heat-trapping insulation as possible, but weight and packability are still a big priority. I’m completely shocked at how light this piece is for how much warmth it provides — it’s essentially a sleeping bag for your upper body and allows you to glass longer and be more comfortable. It’s now my favorite down piece from SITKA.
