@sherry Thanks for reaching out!
Just to clarify: You are asking about the differences between the Big Agnes Copper Spur HV Ul 1 Bikepack Tent, which is orange, and the Big Agnes Copper Spur HV Ul 1 mtnGLO tent, which is gray, correct? If so, the orange model is designed with bikepackers in mind and has shorter pole lengths for fitting onto bike bags, whereas the gray model is an REI-Outlet item and has built in LED lighting in the tent.
Let us know if you have any other questions or if we did not get the tents correct. Thanks!
