We have had over the shoulder work positioning lanyards, bike tubes, webbing slings and full-on chest harnesses to help tend SRT systems on the ascent. Now, we have the latest derivation, the 4SRT Chester Solo, a simple over sling for comfort and efficiency. The 4SRT Solo offers similar multiple connection points to the standard 4SRT Chester for optimum height adjustment. The Solo is girth hitched to the harness and one end and connected with a carabiner of your choice at the other (carabiners not supplied). Sliding buckles front and rear ensure correct size adjustment. Not for PPE. DMM XSRE carabiner not included.
