The Standard Contoured Hip belt works on all of our packs that feature removable belts. Use it as a replacement, or to pair with products where you want to add a belt (J79s G1, G3s main pack, or G1 Little Brother). This belt generally will work well for people with waists of 28"- 40".
If you're looking for a shorter alternative to the standard hipbelt sold with our packs, the HBSS is about 2" shorter. The padded portion of the HBSS is 28" long, but the webbing straps extend to 60", so it will work for a variety of body sizes.
