I looked at the speed harness in Dicks Sporting goods a couple weeks ago. They look good and are very light. Easy to put on and the harness would fit easily under a jacket. Heck, I wear my Rescue One under a jacket without too much trouble and the spider harness is half the weight and not nearly as bulky. I wanted to look at the vest, but they didnt have them when i was there. I am more interested in the live wire they are making. Looks to be a good harness add on accessory.
