I have a Wild country Zephyros 2 tent which has (besides the main pole) 2 5mm fiberglass poles at each end. These poles are 56cm and limiting a smaller pack size. Ideally i would like to cut these in half and use a sleeve when pitching the tent.

Are these sleeves available somewhere ?
Or any custom pole manufacturer who supplies split 5mm poles ?
I only found zpacks so far http://www.zpacks.com/accessories/tent_pole.shtml
