Umbro released the home jersey for Euro 2016 six weeks ago, so it seems unusual that they'd wait much longer to reveal the away jersey - but they are.
Today they revealed that the upcoming away jersey will be launched on the sixth of May, and that it will be white:
The 2016 Ireland Away Kit by @UmbroIreland launches 6/5/15.

Now, the pictures shown don't say a huge amount. The away jersey will also have the latitude and longitude that was a feature on the home shirt.
We know that the back of the jersey will be solidly white, but the front may or may not have stripes based on the picture on the bottom left.
We shall see on the sixth of May.
