For schools who purchase a Brenthaven sleeve to be carried as a stand-alone case, the Tred strap is a necessary addition. Made from 100% nylon webbing, it is durable and comfortable. Its comfort swivel hardware eliminates bothersome twisting and ensures a comfortable carrying experience. The strap attaches easily but securely to custom loops in the sleeve, and is compatible with all Brenthaven K-12 sleeves.
