Thermoregulating

Fitted but not skin tight, the Swift Tech Mockneck LS is meant to function on its own as a long sleeve top or as an optimal base when layering up. The fabric breathes and excels at wicking moisture swiftly away from the body and dispersing it along the fabric face for faster drying. The ultra-soft poly-merino jersey, while intended for high-output in colder pursuits, is thermoregulating to maintain comfort through a wide flux of temps. With alpine-inspired styling and the addition of Polygiene® anti-odor control, this essential cold weather layer can be worn more and washed less.

sustainability

Swift Tech is treated with Polygiene® anti-odor control to inhibit and prevent the growth of bacteria that causes stink. Studies show that washing and caring for garments makes up 2/3 of the environmental footprint over the lifespan of apparel — by wearing more and washing less, even just wearing something twice between washes, can save energy and water, reduce CO2 emissions and minimize micro-plastics.

Swift Tech is also OEKO-TEX® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.

Great for cool to cold weather!

Love this LS from Janji! Material is cozy, fit is dialed in and now that I have experienced “mock neck” there’s no going back to a loose collar, especially while running in the cold!

My Janji preferred

This mock neck is my favorite Janji gear I own. I have trouble finding things that fit. I’m 6’2 180 with a long torso and the large fit like perfectly, including length. It’s warm and It’s also used it as a lounge piece.

Versatile Base Layer

I just received my Swift Tech Top base layer. Ran for an hour in 25 degrees and flurries paired with a Stormrunner Fleece. Warm and softer than typical base layer poly based products . Just awesome! Will definitely wear this casually as well.

Great base layer

I bought this for my husband and he loves it. It is super lightweight, and it wicks well. He's worn it for running, cross country skiing, and hiking high peaks. Really a great piece of clothing.
