The Mountain Hardware Tech Vest is very light; don't even know you are wearing it. Extra cool, breathable, comfortable. Good draw strings, excellent zippers. Fits to size. One small drawback, no inside pocket. This is not important, just a convenience in having an extra pocket. Some may claim the collar is somewhat high, but in cool weather you will definitely appreciate the warmth the upright collar brings to the neck. There is no chafing either way, zipped or unzipped. Irrespective of this, to purchase this vest at Backcountry is well worth the effort. Professional, courteous personnel, and knowledgable staff enhance any purchase. Thanks guys. Rate it easily five stars.
