Overview

The Sea to Summit Ground Control Guy Line Pack of 4 in grey is a compact, highly adaptable set of reflective guy lines designed to secure your tent in gusty conditions. Sold separately, they’re a popular upgrade for Alto and Telos tents, but their versatility makes them a solid accessory for many shelters. The lines feature reflective leads for visibility at night and Quick Connect V-toggles that replace knots with a simple click, speeding up setup and readjustment on the fly.
