Winter's Impact on Jumping in General Skydiving Discussions July 3, 2016 We jump until 15 degrees F and I've jumped even colder than that. It's managable but really, really cold. A couple of times my hands have felt frozen until I dialed in my clothing and gloves. It's a really bad pain and makes it much harder to effectively use your toggles, especially since your hands are up getting even less blood flow. Now that we have three tunnels nearby (US Midwest) it's a lot less tempting to jump in the cold but still fun. My advice is talk to experienced instructors about gear. You don't want bulky gloves or anything that interferes with your handles, etc. I usually wear two pairs of ski socks, two or three layers of Under Armour cold gear, Sirius Extreme gloves, a full face, and a Nike neck warmer thing. I see some people wear ski liners under their gloves which is probably a good idea. The advice about going to Eloy in the Winter sounds good. I've done it and enjoyed it. Eloy has a lot of visitors so be careful out there too.Chance favors the prepared mind.
