Disclaimer: I'm a newb.

Recently got into hammocking, and shortly got myself a Traveler Sock. Before I get to the trouble, let me throw out that this a sweet piece of kit, easily one of my favorites.

The problem: Under high/gusty winds I am getting cold air leaking in fairly notably. Nothing like being open to the wind w/o the sock, but still, I don't like it. I've spent some considerable time trying to diagnose the source of this leak.

1) I thought I'd left the zipper open; a few times, yes, but closing it didn't solve the problem.
2) The Zipper itself leaking under wind; after checking I'm fairly certain not.
3) The hook and loop end closures; these, I'm thinking are the source. of the leaking air. There are two possible causes, I would not be surprised to find both in conjunction.

A) The closures tend to pull back toward the center of the hammock and open up. I am going to order up a pair of micro-biners and clip the sock to the structural ridgeline right below the webbing D rings.
B) The sock is "breathing" as in functioning like a lung or bellows under high/gusty winds. I think this is the most likely issue. The wind plays havoc on the sock causing the internal volume to increase and decrease. The result is the hook and loop ends "breathe" cold air.

Solving the problem:
1) I think it would be worth selling with, or at least recommending micro-biners to keep the sock ends from pulling back and opening over time.
2) I am experimenting with grip clips to create tie-out points. I found today that there was a big difference with vs without. The tie-outs tension the sock, limit its ability to "breathe" under wind and keep me from getting cold drafts. Currently I have one on the non-door side, centered between head and foot ends, and slightly more toward the ridge-line. I put a second on the zipper-side, near wear my head lies. Next time I will place a second on the foot end, and I am considering two rather than one on the non-zip side. I believe a bit of experimentation and adding panel-puls to the basic sock would make a good piece of kit into a superb one.

On a side note, I find the even without the gusty wind issues, the sock gets in my face a bit. I'd be happy for a panel pull just for that.

Anyhow, that's my experience. I'm curious to hear from others. One last reminder, I am not saying that the Traveler sock is terrible (its one of my favorite pieces of kit) I just think it needs a couple tweaks before it's a truly sexy beast.


God bless,
