    Great lightweight jacket

    Published by Markian Tymkewycz on 7th Feb 2018

    Lightweight and pack-able, warm and protects from most elements
    Not 100% waterproof but keeps you dry through a light rain!

    A great jacket for the money...

    Published by Milton Reynolds on 21st Jan 2018

    I got my jacket on sale, so it was an especially good deal, but even at full price this is a great jacket for the money. Warm and easily compactable, this jacket is perfect for wading. It also has handy pockets for storage. They run a little small, so you might want to think one size up, but you won't be disappointed.

    Awesome Jacket

    Published by Chris Harris on 12th Apr 2017

    Been wearing this jacket for a few months now and love it. Quality is outstanding and would easily choose Exterus over competitors with similar offerings. Also very easy to pack. Great job guys!

    Exact same insulation, Primaloft Gold, as a Patagonia Puff

    Published by Unknown on 16th Mar 2017

    This light weight jacket/ windbreaker has the exact same insulation, Primaloft Gold, as a Patagonia Puff. Nice and light, not too bulky. Great for layering. Plenty of pockets. Really holds up to strong wind...none gets inside. I would get this jacket again.

    Like the Jacket

    Published by Tomas Tyler on 22nd Dec 2016

    I like this jacket and it seems pretty warm. I wore it on a pretty cold day here in Texas with just a T-Shirt under and it was fine. I do wish the sleeves were longer though. I'm 6'3 and ordered a XXL. The torso is a good length.

    Excellent Jacket

    Published by Jon Harris on 6th Dec 2016

    Jacket is everything I hoped it would be. Very lightweight, well made, good pockets. It's very warm with just a base layer underneath and this week I used it with a breathable wading jacket on top and I was plenty warm enough in the stream. I can see me using this for hiking in the spring as well as a warm layer for fishing.

    really like this jacket

    Published by NH on 7th Nov 2016

    Warm, water resistant, looks good Fits in my simms freestone sling pack easily. Cuff area dries surprisingly quick after dunking. Large fits me well (6'2" 205 lbs).

    Only things i would change would be to offer a tall size. Its a good lenth for fitting under waders but wearing it out and about it might be a little short for taller people. Second thing would be changing the cuffs from the thin stretchy material to a longer dwr treated stretchy cuff.

    All in all if i could currently afford a second one id buy it and will if the one i have eventually gets too beat up.

    Good Performance, short sleeves

    Published by charles smith on 7th Nov 2016

    I got this jacket through a sales promotion where I paid less to get more in store credit. The jacket was FREE! Because it was free, I didn't expect much, but it seems to be of good quality. It's lightweight and warm, I intend to use it as a night time fishing jacket, under a shell, or as a spring time jacket. The only thing I don't like about it is the that the sleeves could stand to be a inch or two longer, and the cuffs are pretty tight (I'm a big guy, 6'1, 270 I got a XXL). All together, a pretty great deal, this jacket and a kracken xla for $270!

    Surprisingly warm & wind-resistant for the weight

    Published by Olaf D. on 27th Mar 2016

    Warmth: Warmer than expected given the light weight of this jacket. Great for walking the dog on a breezy winter Calif. evening, with just a t-shirt underneath. Also great to throw on after drying off after a surf casting session. Remarkably wind-resistant. Stood in a 18-20 mph steady breeze, and only really felt the wind creeping in at the zipper.
    Fit: I'm 6'4" and it fits me pretty well. I could use an extra 1/2" length in the arms, though.
    Quality: The lack of a fifth star stems from this. Nothing major. The collar is a hair flimsy and doesn't seem to have any insulation/loft to it, and the fold of material at the top of the zipper (presumably to protect your chin/neck from the zipper) doesn't lie flat as it should.
    Overall, I'm quite happy with this jacket. Haven't used it as a layer under a rain shell, but I imagine that combo would be super toasty.
