As temperatures take a dive layering becomes crucial. Enter FirstSpear’s ACM400 Merino Wool line. The FirstSpear Lightweight Vest (LWV) is low bulk, high warmth garment. Additional features include the quarter-zip closure in the front. Along with the external and hidden internal chest pockets which are lined with a lightweight comfort mesh. In the back, there is a hem scoop into a tailcoat style to cover your waistband when active or bending over. The LWV is designed with a closer fit to take advantage of the natural stretch feature of FS400 and be comfortable under a shell or additional layer.

What makes this merino package so unique is that it is a bi-ply material, not a blend. Using a super-fine polyester on the interior and merino wool layer on the exterior, this material combo does some very incredible things. When the user sweats or gets wet the poly layer will quickly wick away moisture from the body and transfer it to the absorbent wool layer. Once the moisture permeates into the wool layer it allows the poly to dry very quickly which helps avoid the typical stink you find with other synthetic layers, additionally wool is naturally antimicrobial which makes it incredibly difficult for the garment to produce bacteria that causes odors in all synthetic base layers. Furthermore, once the moisture is absorbed into the wool layer it will keep the user insulated and warm even when wet.

Another garment in the ACM400 lineup to consider is the Mid Shirt. The Mid Shirt is durable and ultra-soft with a 2/3 length front zipper that allows extra ventilation when you really warm up. The high collar keeps your neck covered and is great for when you are working with a sling.

“Excellent mid layer, insanely comfortable. I’ve been a cotton thermal guy for decades, saving the expensive wool layers only for those coldest hunts/trips. This ACM MID 400 though, has now changed all that. The ability of this shirt to wick sweat/moisture from the body to keep that chill away is awesome. Sizing is accurate and the extra length to stay tucked in is welcomed on this 6’2″ frame. The 2/3 zip allows you to regulate venting and is stellar at keeping wind chill at bay combined with one of the neckie’s. Quit reading reviews, invest in your base layer and thank First-Spear later.” — Online Reviewer
