Cozy warmth


Peached softness


Introducing the new go-to when the mercury drops. Here's a little background on these joggers: when we set out to redesign our performance track pant, we knew it had to meet some key criteria: 1. total freedom of movement 2. excellent moisture wicking performance and protective warmth without added weight 3. secure carrying capacity 4. a comfortable, streamlined fit. The Mercury Track Pant tackles those handedly. What we didn't know then, and honestly did not intend for was to design a running pant that would feel this cozy, soft and all-around comfy. This pant works hard. This pant does down time hard. This pant challenges the notion of what cold weather running gear should feel like.



Cold weather running comfort
Breathable, moisture-wicking Mercury Knit excels at transferring sweat + heat away from the body for comfort during prolonged efforts

For when the mercury drops
Lightly peached on both sides, Mercury Knit has an exceptionally soft hand feel while providing cozy warmth + thermoregulation without added weight

Snug comfy fit
Minimal, flat elastic waistband with an internal drawcord for a completely smooth, secure fit

Freedom of movement
4-way stretch fabric combined with an inner gusset panel + ergonomic seaming on the outer thigh allow for unrestricted range of motion

Hand warmer pockets
Two zip side pockets can stash gloves, wallet, or nutrition while a bungee loop is integrated into the right side pocket to secure keys

Roomy back zip pocket
A secure back pocket with nylon zipper pull can easily secure most phones sizes (with case) while minimizing bounce in stride

Flat hems
Minimal elastic hem bands allow for easy on/off + keep the pant in place when in motion

Janji signature blue reflective logo on front + “watermark” on back ankle increases visibility in low light
