As i've said, it has it's uses, ie, standing around in the rain. Just not ideal for when you need to exert yourself...I'll still wear it, but i'll keep it in my bag for when i stop all physical activities.Thats why these and the rest like them aren't issued anymore. There fully waterproof, not advertised as breathable. Like if you wore a tarp over you the sweat you make wont have anywhere to go. These were made long before Goretex and the like existed, before them it was ponchos being used. Its not really the fault of the jacket it was apparently not bad when it was first issued.
