An adjustable-length tensile member, for example, a strap for a wearable pack, can include a fastener member defining first and second apertures and a cross-member positioned therebetween. A strap can extend through the first aperture in a first direction, over the cross-member and through the second aperture in a direction opposite to the first direction. A cover plate can matingly engage with the fastener member to obscure a segment of the strap from view. Wearable packs can incorporate such adjustable-length tensile members. Methods for assembling such adjustable-length tensile members are also disclosed.
