Amazingly light but cuts the wind and holds the heat in with a layer underneath!

– Joe B., ★★★★★

Choosing the right layer for crisp spring mornings and chilly fall nights can be a challenge. Our Ventum Wind Shell is crafted to cut the breeze and trap warmth in your base layer or against your skin.

Ventum fabric strikes the right balance between cutting cold wind while still allowing enough breathability for sweat to escape when hiking on chilly mornings and evenings.

It’s perfect for when a base layer alone is not enough, but insulation would make you overheat. Weighing under 2 ounces this is a must-have item for when you plan to hike in cool weather.

This windshell is unisex sizing. We do also have some women's sizes in our Bargain Bin while supplies last.

  • Elastic at the back hem, and at the wrists to keep wind out.

  • Elastic at the hood for a snug fit around your face.  

  • Constructed from .51 oz/sqyd Ventum ripstop nylon. This fabric is tightly woven and heat calendared to cut the wind.

.51 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 .51 oz/sqyd (17 g/m²).  Featuring a high quality "C0" 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.

Ventum fabric tests at 39.5 CFM under ASTM D-737.


Weight:
 .51 oz/sqyd (17 g/m²)

Measuring:

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.
