Frequently asked questions
Which legging pocket holds a phone?
A side thigh pocket is the one designed to hold a phone. It sits on the outer leg and grips the phone against the thigh so it stays flat and does not bounce. Waistband and small zip pockets are meant for keys, cards or gels only.
What is a gusset in leggings?
A gusset is a shaped panel sewn into the crotch of a legging. By removing the single central seam and adding a triangular or diamond piece, it gives more room to move, reduces strain on the seams and improves comfort during squats and yoga.
Why do some leggings have flatlock seams?
Flatlock seams are stitched so the join lies flat against the skin instead of forming a raised ridge. This reduces rubbing and chafing during long or repetitive movement, which makes them common on running and training leggings.
