Increased strength, weatherproofness, and internal space are the characteristics of Eureka's new Timberline SQ Outfitter 4. The use of their proprietary SQ frame, incorporating an oversize 13mm ridge pole, provides a strong and resilient frame for extended use. The SQ frames spreader pole increases the tents internal volume by 24% so there is more useable space for cots and gear. Eureka have improved weatherproofness by lengthening the fly and extending the ends of the fly to create vestibule wings for added wet weather protection to the door and windows. An oft overlooked, but greatly appreciated feature of the SQ frame is the raised entry height of the fly eve, making it easier to enter and exit the tent.
