Mad47 0 #1 February 7, 2003 What is the best way to avoid fogging of Z1 visor when jump in cold weather? I know it has been already discussed somewhere but cannot find the post. Quote Share this post Link to post Share on other sites
rigging65 0 #2 February 7, 2003 Try Keeping the lens open until you actually leave the plane, then open it under canopy. If it's really cold, drilling some small holes (like 1/8") along the lens piece right in front of your nose helps...maybe three to start. That helps air flow over the lens and clears it up. Also, try to make a conscience effort to breath in and out through your mouth in freefall... "...and once you had tasted flight, you will walk the earth with your eyes turned skyward. For there you have been, and there you long to return..." Quote Share this post Link to post Share on other sites
BMFin 0 #3 February 8, 2003 Have you tried any anti-fogging liquids ? (If you dont wanna spend any money on it, try soap ) I havent tried but I think it might help... Quote Share this post Link to post Share on other sites
Mad47 0 #4 February 8, 2003 Thanks, The problem is that sometimes I get plenty of fog on my visor before opening. Keeping the visor open until the very last moment in the plane helps, but does not completely solve the problem. I hope the holes will help. There was a big discussion about all kinds of liquids. As far as I understood, lots of people were unhappy with them. Quote Share this post Link to post Share on other sites
billdo 0 #5 February 8, 2003 Actually, I have always had this problem with my Z1 and finally switched to an Oxygyn A3 because one of the 300-way ones was on sale so cheap, but before that I had worked out the problem with the Z1 fogging. Do what everyone said - keep it open until just before jump, drill those holes near the nose. But here's the real thing that works. Pull up all that fabric by the nose and mouth area way up over your nose and make sure there is nothing (no fabric) between your mouth and the slits designed as breathing holes in the helmet. Even consider cutting some or all of that fabric in the nose area out of the helmet. Quote Share this post Link to post Share on other sites

That's what I do... breath through the airhole, works wonders I jump in Maine whenever they put a load up. jumped in some pretty cold weather and fogging hasn't been a big problem with my Z1. my Z1 fits really well so when I breath through my nose the air goes into the cold air thats coming in the air slots... Aviation grade into fogging stuff works well on my glasses that sit under my z1 never needed it for the visor. Quote Share this post Link to post Share on other sites

pilotdave 0 #8 February 8, 2003 Check out http://store.yahoo.com/unfeathered1/thinyoushoul.html. They have all kinds of tips about the Z1 including how to prevent fogging: "ABOUT LENS FOGGING: Although your lens has an anti-fog coating on it, warm air on the inside applied right next to the lens (ususally from your nose) will cause fogging. The problem is usually easily corrected by a simple adjustment of the liner -- disconnect the liner under the nose and reattach it below the actual helmet (visor) opening. This allows better air flow and typically eliminates the problem." Breathing out with your mouth through the holes in front helps too. I've had no problems with fogging in freefall, just under canopy. I always leave it open until just before exit. Of course I've now left the plane with the visor wide open twice now. I've started to never put it up so high I can't see it when it's open in the plane. By the way it survives just fine open in freefall. Dave Quote Share this post Link to post Share on other sites

Mad47 0 #10 February 9, 2003 Huh … I have jumped Z1 wide open too … was watching those chicks exiting on raft dive and forgot to close the visor It catches the air pretty well … weird feeling. Quote Share this post Link to post Share on other sites
pilotdave 0 #11 February 9, 2003 The first time I left it open was a 3 way horny gorilla. Being "vertical," I really barely noticed it. After a little while I was wondering why there was some wind on my face and realized my mistake. The second time, the next day, I was doing a solo. On my belly I sure noticed it quick!

SkySlut 0 #12 February 10, 2003 Now you wont have to worry about a visor fogging up on the A3...you cant have a visor that fogs up when you dont have a visor. I would probably recommend taping that visor down so it wont come off in freefall or better yet...take the visor off and get goggles. Quote Share this post Link to post Share on other sites

I've seen a guy get his goggles frozen to his eyes on a really cold day when his eyes watered. The key to using a full-face on cold days is to avoid getting the inside of it saturated with moist air; either keep it off until just before exit, or keep the visor open and take care to breath through the mouth vent holes.... The only sure way to survive a canopy collision is not to have one. Quote Share this post Link to post Share on other sites
