Phelps Collapsible Bugle Tube

For years, hunters have been asking for a more compact bugle tube design without sacrificing sound quality. In February 2023, Kyle Bradshaw approached us to partner with him and his brother Steven on an industry-changing bugle tube design- the Kyven Gear modular bugle tube. Named after the two brothers, this new tube not only collapses down to the size of a Nalgene water bottle, it also sounds AMAZING! From high-pitched screams to thunderous grunts and chuckles, the Kyven Tube does it all. While not in use, the tube collapses, and each segment nests securely while hiking into your favorite elk country.  To Expand Tube: Hold the larger end in your left hand, gripping the larger two segments, then begin turning the mouthpiece COUNTER CLOCKWISE to unscrew from the nest. Turning the tube upside down, pull the long skinny neck all the way out and continue to turn COUNTER CLOCKWISE (making an effort not to cross thread) until snug. Then allow the middle segment to unscrew COUNTER CLOCKWISE. Once free, pull out and continue to turn COUNTER CLOCKWISE, attaching the largest segment until snug. DO NOT OVER-TIGHTEN!   To Collapse Tube: Repeat expanding directions, but only in reverse, turning CLOCKWISE to return into nesting position. DO NOT OVER-TIGHTEN!  Specifications Expert Insights Product Videos
