The MSR Advance Pro is designed for one purpose: to protect you from the elements at night without weighing you down during the day. The Advance Pro is one of the lightest models we tested yet performed among best in moderate to strong winds. It isn't super versatile and doesn't even feature a bug-mesh door, giving us poor breathability in wetter conditions or at lower elevations. It has the smallest-in-review interior space, making it the least comfortable model to hang out in — but that's not what this tent is made for. Our Top Pick for Lightweight Alpine climbing is for big ascents in the mountains where every ounce counts.
It's easy to set up in strong winds, and its small footprint means you can pitch it pretty much anywhere two people could come close to laying down. While we love many things about the Advance Pro, for most folks who are looking for a summertime alpine climbing tent, the BD Firstlight is better. It's a lot less weather resistant and not as easy to set up but has more space and bug netting, making it nicer for many trips in the lower-48.
