Mizuno Power Warm-Up Pants vs Under Armour Woven Vital Pants

The Under Armour Woven Vital is the safer pick for most shoppers: a 4.6 rating from 100 owners, a defined 31.75-inch inseam, ankle zips and wind-resistant polyester. The Mizuno Power Warm-Up is the warmer, stretchier option, with a nylon-polyester-spandex blend and a drawstring elastic waist, but it gives no inseam measurement and comes in a loose tapered cut. Buy the Under Armour for year-round training and layering; buy the Mizuno if you want warmth for warm-ups and cool-weather sessions.

• Choose the Mizuno Power Warm-Up if you want a warm, stretchy pant for warm-ups and cold-weather training and prefer a drawstring waist you can tighten.
• Choose the Under Armour Woven Vital if you want a lightweight, wind-resistant everyday workout pant with a known inseam and ankle zips.
