We were able to test the X-Bionic Energy Accumulator Wild Shirt LS for many weeks in downhill skiing but also in freeride. We tested this first layer with the pants of the same name and socks.
We still have X-Bionic technical underwear that is more than 10 years old: it is indestructible and almost insensitive to wear. This new version, the X-Bionic Energy Accumulator Wild Shirt LS, is true to its reputation, it uses the good recipes of the X-Bionic of previous years. Wash after wash, the X-Bionic Energy Accumulator Wild Shirt LS does not move. It is also not very subject to the stretching of a mesh with the nails. It does not pill. Another big positive point, it does not stretch.
Solid, durable, this X-Bionic Energy Accumulator Wild Shirt LS offers a compression that can be a little scary at first. The T-shirt seems very small. But the fabric relaxes and we obtain a reasonable compression, which does not oppress. The movements are, in any case, not hindered or limited.
We do not feel any seams, the comfort is high-flying, around the neck, under the arms, at the waist. The mapping of the T-shirt is very well thought out with a complex weave that alternates the compression zones, of great flexibility, more ventilated parts.
In action, it is a rather warm underlayer but quite consistent with a fleece on top, a technical shell.
Perspiration is managed quite well, it dissipates quite quickly if no waterproof layer blocks the dissipation. The X-Bionic Energy Accumulator Wild Shirt LS dries quickly. Odors are limited.
We will not comment on the presumed effect of compression. As in trail running, it is, in fact, very difficult, even random, to quantify the gain in recovery.
Another positive point concerns its assertive look, which intrigues. The X-Bionic Energy Accumulator Wild Shirt LS can be worn alone, assuming its design. It is a unisex product. X-Bionic claims that each piece is unique thanks to a hand-dyeing process. We don't really see how this is possible on a production line, either. In any case, the manufacturing is neat.
