Are these pants warm enough for cold weather?

No. They are a single layer of 100% nylon with no lining or insulation, so they suit mild weather or wearing over a base layer. For cold days, look for fleece-lined or tricot track pants.

Do the pants stretch?

The nylon shell has no stated stretch, and the fit comes from the straight cut and elastic waist. The inner drawstrings let you tighten the waist, but the legs will not give like knit or spandex-blend pants.

How do I pick a size?

The listed fit gives waist and inseam for each size: S 29/29, M 31/30, L 33/31, XL 35/32, 2XL 37/33. Measure your waist and inseam and match them to that chart.

Where can I keep my phone and keys?

There is a back pocket and a hidden zipper pocket inside the left front pocket. The zipper pocket is the safer spot for keys, cards or cash.

Are they good for running or training?

They work for warm-ups, cool-downs and casual wear. The straight nylon cut is not built for high-stretch movement, so runners who want flexibility usually prefer knit or blended training pants.
