The t-shirt feels like silk! It’s not silk, but it feels so smooth and lightweight on the skin that it could be silk. That was my first impressions of the Jack Wolfskin Accelerate Zip t-shirt.

I also like the feminine shaping of the t-shirt.  It is roomy enough up top for boobs and nipped in a bit at the waist with a bit of flair over the hips. If you’re buying this top and like them on the tighter side I’d go for a smaller than normal size, but if you like tops that flatter with a little extra room, then stick with your normal sizing.

The top is made to suit “intense aerobic activities like cycling, trail running etc.” And according to the details, “the fabric feels light and cool, and with active moisture management in the form of Q.M.C. fibres”. All this is topped with mesh inserts at the sides to increase airflow and the high zip collar to offer sun protection (when zipped up) or ventilation (when unzipped).

So, if the top is made for hot and sweaty activity, that was the activity I needed to go for. Cue a hot and sweaty hill run. On a warm-ish day running uphill makes me very sweaty very quickly. I began with a long-sleeved baselayer over the top of the Jack Wolfskin Accelerate Zip t-shirt, but soon stopped to peel off the outer layer.

The t-shirt still felt light and cool, just as the label had said it would. But things were set to become even warmer. The ascent was non-stop for about 400m and although running slowly I could feel the heat begin to rise. Weirdly I didn’t feel any sweat on my skin. It seemed to disappear and although it must have evaporated through the t-shirt fabric the top still felt dry to touch.

At the top of the hill the wind picked up and temperatures suddenly dropped. I stopped again to put my long-sleeved top back on. This would normally be the point when I started to notice a cold and damp t-shirt baselayer but not with the Jack Wolfskin. The fabric had effectively allowed all my sweat to evaporate and still felt nice ad dry against my skin and under my top layer.

The t-shirt actually does as it says on the label.

Added to this is the trademark wolf paw mark that I like so much! (Read my previous Jack Wolfskin kit review blog to find out why.) The price is a little more than I’d normally want to pay for a t0-shirt (£40) but since it works so well at keeping moisture away from the skin I think I might be tempted to buy another.

The top would be ideal for running, cycling, hill walking, canoeing, skiing and any other outdoor activity that makes you sweat! A lot!

I was sent the Phantom (black and grey colour) to try by Jack Wolfskin but the top also comes in far prettier Lake Blue and Peak Red. See Jack Wolfskin for further details. And check out Chelston Direct for great Jack Wolfskin deals.
