Increased strength, weatherproofness, and internal space are the characteristics of our Timberline® SQ Outfitter 4. Our proprietary SQ frame incorporates an oversized 13mm ridge pole to provide a strong and resilient frame for extended use. The SQ frame's spreader pole increases the tent's internal volume by 24% so there is more useable space for cots and gear. Lengthening the fly and extending the ends of the fly creates vestibule "wings" for added wet weather protection to the door and windows. Often overlooked but greatly appreciated, the SQ frame has a raised entry height at the fly eve, making it easier to enter and exit the tent.
