1. A telescoping pole structure for a shelter, the telescoping pole structure comprising:
a shell pole portion extending along a longitudinal axis;
a sleeve fixed to the shell pole portion;
an inner pole portion extending along the longitudinal axis and positioned at least partially within the shell pole portion and at least partially within the sleeve, wherein the inner pole portion slides telescopically relative to the shell pole portion;
a biasing element positioned to bias the telescoping pole structure toward an extended configuration; and
a detent element fixed to the inner pole portion;
wherein:
the sleeve comprises an engagement surface having a plurality of surface positions for contacting the detent element, wherein each surface position is located at a different distance along the longitudinal axis from the shell pole portion than each other surface position;
the sleeve is rotatable relative to the inner pole portion, wherein rotating the sleeve causes the surface positions to move relative to the detent element; and
contact between the detent element and each of the surface positions prevents the inner pole portion from moving telescopically into the shell pole portion.
