The Stretch Tiros is a two person tent that is big enough for campers to have plenty of room during a fierce storm. It has 38 square feet of room, two doors and a vestibule to organize your gear. DAC Featherlite poles, Jake's Corners, Clip Locs and Interlocs keep the Tiros together, no matter hard the wind blows.

DAC® Featherlite NSL Poles
Thicker diameter poles with a thinner wall increases strength and saves weight
Expanded insert combined with a large diameter pole creates a stronger connection point between pole sections
The best strength-to-weight ratio of any tent pole available today
Unique joining insert allows for a cleaner, smoother transition in Reverse Combi Technology (RCT)
DAC® has greatly reduced the use of phosphoric and nitric acid in the anodizing process (cleaner manufacturing makes for a cleaner environment)

Tent Guard with Ultra Fresh
We begin using Tent Guard with Ultra Fresh in 2004 (a Sierra Designs exclusive at the time!) and with great success. Applied as part of the PU coating to our rain flies, floors and footprints, Tent Guard extends the life of a tent by thwarting mold, mildew and fungus. Particularly on extended trips or in damp climates, Tent Guard protects a tent if it is packed or stored temporarily while wet — another bit of piece of mind for your customers.
