UD Mountain Vest 4.0

If it involves a mountain, it should involve the Mountain Vest 4.0 - any discipline, any time.

The new 4.0 Signature Vests have been taken to a new level. The 4.0 vests now feature Comfort-Cinch technology and lighter weight for the ultimate combination of comfort and performance.

Technical materials provide performance and comfort and for technical terrain. Knit Mono Mesh ensures the 4.0 vests stay in place. No movement, no chafing, full comfort.

Athlete-designed details work for everyone. Improved trekking pole holders that don't bounce, and larger sized phones are accessible up front.

The new Comfort Cinch technology provides a custom fit with easy on-the-go adjustment.

4-way stretch woven mesh material with dissolved thread stretches to fit more and is light than ever. This material uses a method to dissolve thread from the fabric. This method improves the strength to weight ratio while allowing for maximum 4-way stretch and durability.

30D Coated Nylon Ripstop: Ultra lightweight nylon fabric uses a rip stop pattern for added durability. There is no polyurethane coating for maximum weather resistance and durability as well.

Micromono Mesh: At 55g/m2 this fabric is extremely lightweight with a woven structure that promotes durability. It is made with a mono filament which improves breathability and does not absorb any moisture.

150g Flex Mono Mesh: This is an ultra lightweight mesh that is soft to the touch. Using a knit structure allows this mesh to be comfortable and very breathable at the same time. It is made with a mono filament which improves breathability and does not absorb any moisture.

Redesigned trekking pole holder minimizes bounce and snaps out of the way when not in use.
