Four years running - ALPS Mountaineering Tri-Awning

Have used this the past 4 years for an annual week long camping trip. Was a cheap purchase the first year and meant to upgrade, but find it basically fit what we needed to cover a campground table. Easy to put up, but needs to be tied down well as it bends easy in a strong wind. I would see that as an issue if used on a beach. It has one wall, but we always drape the other wall, or all three if it rains. Haven't endured any heavy rain, but I would just cover it with something heavier. With a propane lantern going, it warms up underneath when it gets cold.
