The Active Kollection

Janji | Groundwork Flyby Tight - Astral



"TAK thinks this unfussy fit allows you to focus on your run, and your run alone"

The updated Flyby Tight features hi-vis reflective taping along the side seams, a dual-lined front-panel for extra wind-blocking warmth and security where it's needed most, and four roomy pockets for all your carrying needs. Built from a durable stretch nylon that resists odors and won't sag-out during serious efforts, these tights are designed to minimize distractions and provide an unfussy, streamlined fit.


- Breathable, moisture-wicking fabric provides light compression with an unnoticeable feel in stride
- Durable nylon stretches with you and retains its shape while resisting odors 
- A minimal waistband with internal drawcord stays snug + comfortable Extra support
Double-lined fabric in the front panel (from hip through thigh) for added protection + warmth
- Two deep side pockets can easily accommodate the largest phone sizes plus case and minimize any movement or bounce 
- An internal waistband pocket can stash card/cash or key 
- Back dual-sided-entry stretch pocket can store nutrition + dual as a pass-through for a shirt
- Articulated ankle shaping and a laser cut hem allow easy on/off + adaptable wearability to roll up the tight when warm 
- Integrated hi-vis reflective tape along the side seams along with Janji signature blue reflective logo and “watermark” on back increases visibility in low light.
