The Sierra Designs Convert is an innovative and top performing single wall tent for alpine climbing. It has a removable vestibule for extra space and removable poles that can add extra support to the four corners. This tent is highly versatile and rock solid in high winds. It competes most directly with the Nemo Tenshi, which scores slightly higher in our ratings because it has better ventilation and slightly better features. Even so, the Convert places among the top of the pack of the 23 tents we compare. It is our second highest rated single wall tent. Bonus: it can often be found for significantly less cost than the Nemo Tenshi.
Currently the Convert is a bit hard to find from online retailers. You may want to also consider the Mountain Hardwear EV2 which scored slightly higher than the Covert and is available at many online retailers.
