    1. Surprisingly warm & wind-resistant for the weight Rating

      Posted 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.

      This is my favorite jacket of the primaloft material jackets, I have a few Simms and Kast jackets and Allen jacket is the best of them all. Allens has the primaloft gold which is the best material available and is 20 grams more materials for the same price as the competition. You don't feel the different between the competition jackets and Allens until it gets colder and colder then the additional 20 grams makes a big big different. Trust me, I tested all my jacket and I guess that's why my fiance took my BEST jacket to use for herself, Oh well, I'll have to buy another Allen's jacket. My fiance is pretty fussy about fashion, and she took my Allen's jacket over the other competitor's jacket. I don;t know why I keep saying its my jacket, because I no longer have it to use anymore. But a great jacket, good looking and very comfortable. I too have the old style Allen's jacket I brought a year ago and it appears this new models with same material has to be great too. I am going to buy myself another Allen's jacket. Thanks Justin for a great jacket

    3. Awesome Jacket Rating

      I've had this jacket a couple months now and I really like it! Very functional, plenty of pockets, and pretty warm for a thinner jacket. Would definitely buy again!

    4. Great jacket, regulates heat well Rating

      Posted by Jeff on 23rd Oct 2015

      I've had this jacket since last fall (mine was originally released under the Allen brand before Exterus launched) and have been wearing it ever since. The best thing I can say about this jacket is it regulates heat very well. On a float trip this past week, it was just above freezing when we got on the water. With just this jacket and a t-shirt under it, I was plenty warm. I kept the jacket on as the temps climbed toward lunch time. Only after it got near 60 did I take it off. It packs up nice and small to go into your bag and get out of the way so you can keep fishing. Then, as the sun started to hide itself behind the mountains and the temp on the river dramatically dropped, I put it back on and never missed a beat. I love this jacket.
