Syilx people (Okanagan), traditionally used these tule mat teepees for summertime housing. The mats are constructed of tule mats that could be rolled up for easy and light travel. During the spring, summer, and into the fall, Syilx people would dig, gather, hunt and fish. The reeds will expand during rain and create a waterproof shelter. These teepees are still being made and used, however canvas teepees are quite popular.
