A Lot of Jacket But Still Lightweight

    Full Disclosure First: I am a Dynafit sponsored athlete. So I will only describe objective observations - both positive and negative - and will resist using judgmental words like, "better" or "best." But not many people have been in this stuff, so I will share my experiences.

    The Transalper is truly a unique jacket. It is almost a new category of jacket. It clearly excels while you are pursuing aerobic activity in the alpine environment.

    Material Weight / Hand: It is lightweight, but not featherweight. If you're familiar with Patagonia, it is lighter than a Simple Guide Jacket, but heavier than a Houdini or Nine Trails. It is soft to the touch - almost silky.

    Weather Resistance / Breathability: What has surprised me so far is how breathable and comfortable the jacket is, and yet it cuts wind extremely well. I have worn this jacket on cold morning starts, and it has made a huge difference in allowing me to warm up. But what has been really neat is how long I keep it on for. I don't over heat or get clammy. It's more than a simple wind jacket, but it's definitely not a heavy soft shell either.

    Pockets: There are a lot of pockets on the jacket. There is one on the breast. There are three in the back like a cycling jersey. There are two drop in pockets inside.

    Size / Fit: The fit is small. In every other company's jackets I would wear a small for a jacket like this. In the Transapler, a medium fits me perfectly. I am 5'8", 140 lbs. I am thin, but not pro cyclist thin. If you are between sizes, go up one.

    Sleeve Design: The sleeves can be pulled off the jacket with one hand by reaching across your body, over the opposite shoulder, and grabbing a tab on the back seem. It is easy to reach and find. When you pull on this, the zipper is separated and the sleeve is easily pulled down off your shoulder. The sleeves are then easily stuffed into any of the pockets.

    But it doesn't actually become a "vest." There are still really thin, stretchy short sleeves attached to the body of the jacket. The material is almost like a thin rash guard used for surfing.

    I have not been able to put the sleeves back on while still riding. It is extremely fast to put them back on, but you have to start the zipper in the back of the shoulder, so it is easier when off the body.

    So far I have been using this piece intentionally, rather than bringing it "just in case." It has been an incredible "warm up" jacket, meaning I start with it on in the cold, but can keep it on a long time because it breathes well. Then I rip the sleeves and this has been buying me even more time before I have to stop. I find I can dress lightly underneath.
