I haven't been skydiving a lot, but 1/3 of the jumps I've made (okay, 4!) have been in cold weather, and I got a few good tips from fellow experienced jumpers. First, I wouldn't recommend getting all suited up like you're going skiing. UnderArmour is amazing, but on top of that, layers. You should be fine with a light jacket underneath a jump suit. Basically you want something to break the wind, I used windbreaker pants that day and I was relatively fine. As for your hands, MAKE SURE you have gloves!! You want to be able to actually feel your pilot chute, so numb hands are no bueno. Anything to cut the wind is good, but I jumped once with a friend's extra pair that had the pointer finger tip missing for extra dexterity, and I felt like I was going to lose that one part of the finger, the rest of the hands were fine. My suggestion if you don't have a pair of gloves, go to Home Depot and pick up a pair of "subcontractor" gloves. $15, but they're just as good as any sporting gloves and they're indestructible. Also, if you're jumping in REALLY cold temperatures, get a box of blue nitrile gloves (box of 50 for $5), and put a pair on underneath your jump gloves to cut more wind. Just put them on right before you jump out, if you wear them the whole ride up, you'll be sweating in them and that defeats the purpose. One last thing to note is what type of plane you're riding up. I jumped out of a Twin Otter and King Air and the ride up took 10 minutes to 12.5K, so it wasn't bad at all, but when I went up in the Cesna, the ride took forever and I was FREEZING!!
