" DETACHABLE SIDEWALL- Easily attach or remove the sidewall for more shade, light, or privacy. For the all-sidewall model, you will have windows and a door which makes you feel in a private party room. WIND RESISTANCE - The upgrade feature of the sand bag and flat pegs promises a more stable and sturdier using experience. The removable heavy-duty sand bags(four) can secure the tent in sand easily. The uneven top promotes airflow and lower wind pressure. We value your safety and convenience. · COLLAPSIBLE & LIGHTWEIGHT - The canopy is made with a lightweight steel frame and has a collapsible feature that makes it easier for you to transport it wherever you please. · Easy SET UP & CLEAN UP: Setting up the canopy is very easy: just unfold the frame and attach the tent onto the poles. To make the canopy stabler and safer, tit the sand bag with sands (as needed). Store away-take off and fold up the tent and release the poles from the joints. Fit it into the carrying bag and you are done. Clean-up is also easy: just wipe off with a towel or clean with soap and water. · BONUS CARRY BAG w/ WHEEL- The compact carry case along with wheel allows you to move your canopy easily. The small pre-set case saves your room when not use. Bring the sunshade around easily."
