Amazingly lightweight, easy to pack down and a must to bring EVERY time you are going to hike! It is a MUST have item while backpacking. Love that it keeps those damn mosquitoes at bay AND is breathable. Great wind layer. Why isn't this item in your shopping cart yet?

Layering doesn’t have to be complicated. The Ventum Shell is perfect for those chilly early morning temperatures and windy alpine evenings. Specifically designed for women, this wind shell jacket is ounce for ounce the most valuable piece of clothing you can carry.

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

It cuts the breeze and traps warmth in your base layer or against your skin. This is an essential piece of gear when a base layer alone is not enough, but insulation would make you overheat.

If you don't see your size, we also have some sizes available at a discount 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, while still being breathable and allowing good vapor transfer so you don't get clammy. It is more comfortable for every day hiking than a rain jacket.

  • Mosquito proof

  • Highly wind resistant

  • Excellent vapor transfer / breathability - comfortable to wear, not clammy

.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.

 .51 oz/sqyd (17 g/m²)
