Strap Lab by Blackpack: replacement crossbody and waist straps in 25 and 40 mm, a third attachment point and the magnetic Fidlock buckle. Pick the length and carry style that suits you.
Which bag strap to choose
- Single-sided strap, 40 mm: the buckle sits on one side, so the strap stays close to the bag. Sizes M (55–90 cm) and L (80–140 cm).
- Double-sided strap, 40 mm: center buckle and the widest range, from 25 to 125 cm.
- Third attachment point: an extra strap that keeps a belt bag steady on your back.
- Magnetic Fidlock buckle: a metal buckle that connects with one touch.
- 25 mm straps for the EDB line: wide, narrow and thigh strap.
- Carabiner straps for the Street Pouch: with a buckle and simple.
To pick a strap, check the attachment width on your bag: 40 mm for most Blackpack belt and crossbody bags, 25 mm for EDB bags, carabiners for the Street Pouch.
Frequently asked questions
Will Blackpack straps fit other bags?
The straps use standard 25 or 40 mm widths with buckles or carabiners, so they fit many bags with the same attachments. Check the attachment width of your bag first.
How do I know which strap fits my bag?
Check the attachment width: 40 mm fits most Blackpack belt bags and crossbody bags, 25 mm fits the EDB line, and carabiners fit the Street Pouch. Compatibility is listed on each strap’s page.
What is a third attachment point for?
It connects the waist strap to the bag at one more point and keeps the bag in place on your back while running, cycling or moving actively.
How long are Blackpack straps?
The one-sided 40 mm strap comes in M (55–90 cm) and L (80–140 cm). The two-sided 40 mm strap adjusts from 25 to 125 cm.
