Perspiration and Zero-P

Recommended Posts

It seems that no matter what the temp is, when I'm packing I sweat.

Who here hasnt dripped sweat all over their main while packing?

Has anyone ever done any tests to determine the long term effects of the salt and other "ingredients" on the Zero-P fabric?

Is this something that should be washed off?

People say such horrible things about canopies being exposed to salt water, which has always puzzled me regarding the sweat issue. It isn't a surprise that the center cell tends to be the one that goes bad on an old canopy, maybe largely due to that.

Conventional wisdom for a salt water soaked canopy is immediate rinse in fresh water. You'd think that occasional rinse to remove sweat (and hair gel, and deodorant and....) MIGHT be a good idea.

Don't you mean the TAIL.



Center cell from the bridle attachment point to the tail.

If this is true it would certainly implicate perspiration, skin oils and secretions, cosmetics, deoderant/antiperspirant, colognes, etc.. since this would be the area where the most contact between skin and nylon occurs.
(At least when I pack)

Would an occasional wipe with a warm, damp cloth in this area be a good idea?

I would try and limit the amount of sweat, etc that got on the canopy. Once the salt crystalizes, rinsing is the best way to get it out. Wiping it down may dissolve the salt but doesn't remove the dissolved salt from the fabric, so that once the fabric drys, the salt re-crystalizes.

Completely rinsing a canopy is a time consuming process which also damages the canopy by increasing the porosity of the fabric.

Wear a t-shirt when packing and maybe keep a towel nearby to wipe away sweat, etc as you go.

Yeah - what they said. A long sleeved t-shirt is all good. Prevention being better than cure and all that. There must be a rigger or two in the house that can offer some advice on what to keep away from your canopy (when packing).

The only thing worse than a cold toilet seat is a warm toilet seat.

In addition to the sweat, the center cell from bridle to tail also is the part that rubs against the d-bag on deployment, and takes the first shock on opening, both leading to faster wear.
