An outdoor support strap for holding a user in a squatted position above the ground surface while defecating preferably includes a flexible and elongated body suitably sized and shaped to be positioned around a user's waist while being anchored to a support surface such as a tree. The body is preferably formed from an elastic material such that it remains deformably resilient for providing a resistive force against the user's waist. In this manner, the user is able to lean away from the support surface and assume a squatted a position to thereby extend his or her legs forwardly of his or her buttocks. Such a support strap alleviates the strain and energy required to maintain a squatted position for an extended period of time. By using the support strap, the user's hands remain free to hold objects or cleanse the buttocks area with toilet paper for example.
