@GunaG thanks for reaching out! We will work on tracking down those specific numbers for you. In the meantime, we'd love to provide some suggestions on good tents for the activities you will be doing. What kind of mountain hikes are you considering, where and during what times of the year? Will you ever be on snow? 

Both tents you list above have fully waterproof rainflys and bases, and when staked out properly, each creates a vestibule in which you can have your gear fully covered. In addition, proper ventilation during set-up and proper maintenance over time are critical to ensuring your rainfly successfully and continually keeps your tent and gear dry.

At REI, we believe time outside is fundamental to a life well lived.
