I purchased the tumpline replacement for a 30 year old Duluth Pack brand bag purchased from the gear exchange, and sure I could have gone to them for a tumpline, but the quality of Frost River's products is second to none. The only reason that pack was purchased in the first place is it was before the time of them selling out so quality is a bit better than what it is now. Parts, pieces, bags, gifts, to Frost River I go, for life!
