Intended for the intermediate climates between the heat of the summer, and the frigid temps of the winter, the Zerodark™ vest gives shooters the ideal blend of core temperature comfort and freedom in range of motion.

Comprised of Fitelite™ nylon, the Zerodark™ vest has a lightweight outer chassis designed by Viktos with an added water-resistant Dupont™ Teflon® coating for longstanding outdoor use. The Zerodark™ vest also includes an inner layer of 100g Thermolite® insulation for temperature regulation and to serve as a windbreaker.

Exterior

At the top, the Zerodark™ vest has a high collar roll to protect from rifle sling abrasion or wind. A full length YKK zipper has a nylon pull tab with rubberized ends.

The sides include Viktos’ Attackposture™ design, that incorporate four-way, flexible back and underarm panels to give improved flexibility to accommodate a variety of shooting stances.

Along the bottom there are two chest-rig stylized cargo pockets in the front (one each side). These are secured by hook-and-loop, and include nylon draw-string tabs with shrink-tube ends. A low-profile side pocket on each side behind the cargo pockets include a zipper enclosure with a plastic pull tab.

Both sides of the Zerodark™ vest include Viktos’ Gunvent™ design, a unique, dual-zippered side that allows for immediate access to range belt or holstered sidearm while wearing the jacket.

Interior

The interior sides of the Zerodark™ vest have one large and one small angled accessory pocket on each side. In addition, the Viktos “Undefeated” logo appears on the right side front interior.

The Zerodark™ vest is available in Nightfall (featured), Ranger, or Coyote and sized between Small to 3XL.

Product Evaluation Scores:

• Cost – Good (4/5): Viktos currently has the MSRP for the Zerodark™ vest at $120, but is discounting it to $102 as the company prepares to rotate stock for the 2020 spring. With its materials and design, the Zerodark™ vest is both lightweight and functional that keeps the upper core warm despite the wild environmental changes of the spring or fall. In comparison, vests of similar make/material include the 5.11 Peninsula Insulator Vest ($99), Triple Aught Design Syntax Vest ($170), or Arc’teryx Atom LT Vest ($189) – all of which demonstrate the market for designer tactical clothing. As such the Zerodark™ vest, at its current available price of $99, makes it very competitive and among some of the more balanced options on the market given its design and materials.
• Comfort – Good (4/5): Given its lightweight material, and thickness of the insulation layers, the Zerodark™ vest was very comfortable in the early spring weather here in Missouri. Worn in average morning temperatures of 50s-60s, rising to low 70s by mid-day, the Zerodark™ vest allowed for comfortable regulation of temperature and adjusting comfort. The only notable negative aspect was in light winds where the Zerodark™ vest was limited in keeping the overall comfort maintained simply because of the lacking sleeves. Viktos does offer a full-length light Zerodark™ jacket made from the same design and materials, should there be those more interested in overall upper body coverage. The high collar did an excellent job of mitigating abrasion from the sling, and the Attackposture™ design did well to adjust to the more dynamic movements of the upper torso on the range.
• Durability – Fair (2/5): There was an almost grid-like stitching pattern on the outer shell of the Zerodark™ vest that lends to its overall strength in durability. The outer layer was permeated with Teflon which gave it an almost slick feel between the fingers, and helped resist abrasion from things like sliding slings, gun belt, or other accessories. There was minimal double line or overlap stitching, and what was observed was around the zipper or collar line to reinforce the material there. While some thread excess was noted (and easily removed), it was most likely attributed to the manufacturing process. However, prior to conducting range drills there were at least two missed stitches observed; one at the collar line and the other on the interior liner that could also be explained by lapses in the manufacturing process. While minimal, and unlikely to affect the durability of the product in the short-term, over a longer period the threading could become compromised. Indeed, following use on the range, the missed stitch on the collar had broken and the threads needed to be cut. Obviously one recommendation for Viktos would be to consider adding bartack stitching in/around the zipper, along the pockets and its hook-and-loop panels, or high abrasion/tension points.
• Functionality – Average (3/5): The Zerodark™ vest adequately fulfilled its role as a base layer vest for light-to-moderate use—as well as served as an alternative to the Zerodark™ jacket. In that role, the material did keep the user’s central core very comfortable, while the sleeveless design helped to regulate excess heat. On the range, the high collar proved well placed and the Attackposture™ panels did provide for good flexibility in more dynamic movements to the side or in twisting. The YKK zippers for the front and on the Gunvent™ sides provided for smooth and quiet function. The chest rig pockets were very wide and allowed for multiple rifle magazines to be kept there, though it did increase the bulk of the vest. There was sufficient material to close the vest with an IWB CCW holster worn, though access through the Gunvent™ was a little tricky as opposed to simply lifting the vest and conducting the draw. With a gun belt worn (secondary handgun, mag pouches, IFAK), the vest did not have sufficient material to cover the belt and still be closed in the front. It was only with the Gunvent™ open on the side, to allot for room for the OWB holster, was there sufficient material to close the vest. It was noted that much like the Gunfighter Flannel Jacket, the Gunvent™ zippers would inadvertently open from the bottom if the sides of the vest were slightly pulled. Again, this is a common problem with other fleece and light jackets with a similar side opening, and one resolved by having a covering material (secured via snap button) over the bottom of the zipper to secure it as well as reinforce the closure. Viktos may want to consider that as an improvement in its next Gunvent™ design.
• Weight – Good (4/5): Extremely lightweight, the use of the Thermolite as an insulation later allowed the Zerodark™ vest to weigh in at 13.7 ounces while still maintaining the core temperature without excessive bulk. The Zerodark™ vest was even light enough, that Viktos added a loop behind the collar by which to hang the vest to dry when wet. For tactical vests of this type, the market runs the gambit in both material and design (of various weight reflecting those factors). For instance, 5.11’s Peninsula Insulator Vest (16.8 ounces) runs the more traditional design, similar to the Zerodark™ vest with its insulation, pockets, and a quick access sides. Whereas in comparison, the Arc’teryx Atom LT Vest (7.8 ounces) is a more minimalist design we few pockets and intended more to serve as a base layer in conjunction with other outer garments. Regardless, the Zerodark™ vest was still one of the lightest vests available that offers insulation and some level of tactical function. Viktos could likely add additional reinforcement stitching to key areas without significant increases to the product’s weight.

Overall Rating – Above Average (17/25)
