Just reviewed in Road.C.C "If you need one jacket for everything, this does it well."- who are we to argue with that.

The Planet X 365 Magma is our ultra-versatile, convertible jacket, perfect for inclement weather and colder conditions. With zip-off sleeves, it quickly converts between 3-season jacket and race jersey meaning you can carry less kit and remain comfortable regardless of the weather.

    Adding a review purely for sizing as this may help others. Not ridden in the garment yet. I am 5ft 8 and 10.75 stone. Not a skinny whippet but not carrying more than half a stone weight I'd ideally lose. On advice from Planet X I ordered a Large even though I am a medium normally. They were not wrong. Large us bang on for a comfy snug fit. I only just got the zipper on so I have no scope to grow my belly! Arm length is good. Unzipped arms and the short sleeves are roomy for my skinny arms but still fine. It is winter training garment after all. The bumflap is quite big but I can see it is easy to tuck it under the back if you want. All in all very good fit and great value for money. Shame I have to wait til Christmas to wear it.

    I dont usually bother with reviews but had do for this jacket. Bought the red as I like to be seen and a lot of other jackets of this type only come in black. Yesterday I did a 100 mile ride and it never stopped raining but wearing this I never felt wet or cold. It was about 6 to 8 degrees all day and at times absolutely throwing it down. Underneath I wore a summer sleeveless vest and a 365 light long sleeve base layer and I never felt damp from sweat even though when I got home the inside of the jacket felt damp but being warm on the move it wasnt an issue. I worried that rain may work its way down the sleeve from the opening at the top but if it did I never felt it as the short sleeves come down a decent distance. Putting the sleeves back on whilst wearing the jacket is tricky, either take it off or ask a ride buddy, but if its warm enough to remove them you probably wont need to put them back on that day. All in all brilliant jacket, why spend 3 or 4 times more just to get an Italian name on a jacket.
