Big Agnes' Bitter Springs UL 1 Tent brings only the basics for an ultralight backpacking experience. In spite of its basic design, however, the Bitter Springs is host to an oversized vestibule that you can sit under in bad weather. Big Agnes built the fly and floor out of PU coated ripstop material to protect you from the elements,. The mesh walls provide cool comfort in warmer weather. The Bitter Springs UL 1 requires two trekking poles for the setup. One pole has to collapse down to forty inches, and the other to thirty. Big Agnes included one DAC Pressfit Pole that rounds out the interior for a roomier feel. DAC Twist Clips and Jake's Foot attachments make for an easier and secure setup. Internal mesh pockets keep your small valuables in check.
