As far as performance I don't have any issues at all. Worn this in temps down in the mid 30'sF, and it kept the chill off. However, after only a few months of use, this vest is falling apart. The elastic is popping through all over the place and the front is beginning to look like a pimple faced teen. Probably why it was on sale for $35.00.
For Capo higher end clothing, this was a huge let-down.
Wore this for the first time in a steady, but light rain, and it does what it's suppose to; keeps the rain out, however, I was pretty wet on the inside from sweat. The arms on the interior were completely wet from top to bottom, and this was with the main zipper down a bit and the arm velcro tabs open. I had an extremely thin merino shirt on, and, this too was soaked.
The fit is good, however, I would put in some under arm pit zips to allow for more breathability. A pocket or two would be nice, as well.
Will this pack down to fit in a jersey back pocket? If not, any suggestions for waterproof/breathable that will pack down other than the Gore Oxygen?
...... that hasnt already been mentioned? I am 61 and 190 lbs (athletic frame) and find that the XL fits comfortably, but not form fitting.
For the most part, this is my go to jacket for my early morning commute & those cool foggy days that consume the coast of Central Calif. I have worn it a few times on those cold mountain descents as well, and find that when not needed, it packs well in any jersey back pocket. I, too, find that wearing a thin merino baselayer has been more than suffice to stay warm. Breathabiltiy I give an A+++ & the water resistance is outstanding, also. If you're looking for "waterproof" this isn't the jacket for you as this is an outstanding "windstopper" with fantastic water resistance qualities. I have the orange/black and along with the reflective stripes on the sides & back it makes you highly visible. I definitely recommend the Xenon without hesitation.
.... on those cool, breezy early morning jaunts. This jacket has definitely added to the comfort of my early morning commute to work, as well as, those cool descents down the mountain roads. I've only had this down in the mid 40's, but found that all I needed was a light merino wool baselayer under it, and still found myself to be very comfortable. It breathes well and the water resistance factor gets "two thumbs" up! The front zipper is a tad small, however, I haven't found it to be a problem even when wearing gloves. Key factor on top of comfort and warmth is its packable quality; fitting nicely in any rear pocket. It is a pricey jacket, but I would recommend it to others time and again.
