.59 oz/sqyd Ventum Ripstop Nylon

This super light, high quality, 7 denier fabric has a ciré finish on both sides and weighs in at just .59 oz/sqyd (20 g/m²).  Featuring a high quality "C6" durable water repellent (DWR), this ripstop and tear resistant material can also handle a light sprinkle but is not waterproof.

Ventum nylon cuts the wind while still allowing for excellent vapor transfer that makes the fabric highly breathable. With a soft texture, Ventum is not sticky or plasticky like some other fabrics in this weight range.

As the material is down and mosquito proof, it is an excellent choice for wind shell clothing and sleeping bag shells.

 .59 oz/sqyd (20 g/m²)

Made in Japan.


Measure your chest using a string or cloth tape measure and go by the "Fits up to" size. The "Fits up to" size includes a few inches of wiggle room for layering. The jackets are straight cut (like Men's jackets) and do not flair out at the hips. 

They are fine for women, but make sure your hips will fit the bottom hem girth, or size up.  A women's specific version is also available here.

Terrific garment, far lighter than any other shell

I do most o fly hiking and backpacking in the Sierra Nevada of California. In summer and fall, there’s the occasional shower, and any prolonged rain will show up in the weather forecast. So I just need something to lock in the warmth over my fleece for lunch on a windy ridge or cold evening and mornings in camp. I don’t need a 12-ounce parka. This does the job for that. Kept out howling winds last week and is only 2 ounces.

My most used piece of gear

I wanted to let you guys know how much I love this wind shirt. I just finished thru-hiking the AZT and hiking in the Cordillera Blanca in Peru (above 16,500’). First thing in the morning I’d put this wind shirt over my base layer and start hiking. Typically this is all I needed to keep my core temperature up while hiking. Up on the high passes in the Andes I’d slap this puppy on, and I was good to go. I’d also wear it over my thermal top on really cold nights in the Andes. On the AZT I paired this with an 3.0 oz umbrella for rain protection.

Thanks for the awesome gear

“The windshirt is also great for when we hike to caves in cold weather, usually the hikes are very demanding and treacherous, so the heat trapping ability of your windshirt really helps without overheating me before we get into the cave. It also packs down super small so I can throw it into my caving pack to have available when we exit. It is also good to put over my alpine puffy when the wind really starts blowing and I'm exposed and taking a break on the side of mountain, above treeline. “

I used it almost every day

"I can not imagine how it would have been on my trip in Iceland without the wind shell. The function, the weight, and the bulk were stupendous. I used it almost every day and often I missed not having pants in the same material."
