the first strap is threaded through the second strap adjuster via an opening dimensioned to provide resistance to movement of the first strap.
8. The apparatus of claim 1 , wherein:
the first strap is threaded through the second strap adjuster over an area of the second strap adjuster where the second strap is coupled to the second strap adjuster; and
the second strap is threaded through the first strap adjuster under an area of the first strap adjuster where the first strap is coupled to the first strap adjuster.
9. The apparatus of claim 8 , wherein:
the first strap adjuster comprises a first interior friction surface that, when the second strap is threaded through the first strap adjuster, is enclosed by the first strap adjuster; and
the second strap adjuster comprises a second interior friction surface that, when the first strap is threaded through the second strap adjuster, is enclosed by the second strap adjuster.
10. The apparatus of claim 1 , wherein at least one of:
the first strap adjuster comprises a single-threaded strap adjuster with a single opening through which the second strap is threaded; or
the second strap adjuster comprises a single-threaded strap adjuster with a single opening through which the first strap is threaded.
11. The apparatus of claim 1 , wherein at least one of:
the first strap is coupled to the first strap adjuster via insert molding; or
the second strap is coupled to the second strap adjuster via insert molding.
12. The apparatus of claim 1 , wherein at least one of:
the first strap is coupled to the first strap adjuster using an adhesive; or
the second strap is coupled to the second strap adjuster using the adhesive.
13. A system comprising:
an artificial-reality headset;
a first strap comprising a distal portion coupled to the artificial-reality headset via a mechanical linkage that enables the distal portion of the first strap to rotate relative to the artificial-reality headset;
a second strap that is positioned to at least partially overlap the first strap and that comprises a distal portion coupled to the artificial-reality headset;
a strap adjustment mechanism comprising:
a first strap adjuster, wherein a proximal portion of the first strap is coupled to the first strap adjuster and the second strap is threaded through the first strap adjuster; and
a second strap adjuster, wherein a proximal portion of the second strap is coupled to the second strap adjuster and the first strap is threaded through the second strap adjuster.
14. The system of claim 13 , wherein:
the second strap is threaded through the first strap adjuster via an opening dimensioned to provide resistance to movement of the second strap; and
the first strap is threaded through the second strap adjuster via an opening dimensioned to provide resistance to movement of the first strap.
15. The system of claim 14 , wherein the openings in the first and second strap adjusters are dimensioned to maintain a position of the strap adjustment mechanism while the first and second straps holds the artificial-reality headset against a face of a user.
16. The system of claim 14 , wherein the openings in the first and second strap adjusters are dimensioned to enable a user to adjust a position of the strap adjustment mechanism while the artificial-reality headset is being held against a face of the user by the first and second straps.
17. The system of claim 13 , wherein
the distal portion of second strap is attached directly to the artificial-reality headset.
18. The system of claim 13 , wherein:
the artificial-reality headset comprises a rigid support frame element dimensioned to physically support a display of a head-mounted display system in front of eyes of a user when the artificial-reality headset is worn by the user;
