Figure-8 vs Bowline
Figure-8 vs bowline — figure-8 is the modern climbing tie-in standard; bowline is faster to untie after weighting but requires more care. Compare them side-by-side.
Both the figure-8 follow-through and the bowline are tie-in knots — they connect the climbing rope to your harness. The figure-8 is the standard taught in every gym worldwide because it is foolproof to inspect and almost impossible to tie wrong in a way that survives weighting. The bowline is older, faster to untie after a hard fall, and produces less rope flapping — but it can capsize or work loose if tied poorly or left unbacked-up.
This comparison covers the practical differences. The figure-8 is the right answer for almost everyone, almost all the time. The bowline is a respected alternative used by some experienced climbers who understand its trade-offs.
The differences
Figure-8
- Ease of inspection
- Easy — five distinct curves that are obvious at a glance. Partner checks are reliable.
- Untying after a fall
- Hard — the knot welds itself tight under load and can take minutes to work loose.
- Reliability when tied wrong
- Very high — even a sloppy figure-8 holds. Hard to fail catastrophically.
- Backup knot required
- No — a figure-8 follow-through with a clean tail is complete.
- Used in gyms
- Standard — every gym belay test in the world uses figure-8.
- Used outdoors
- Universal — sport, trad, and big-wall climbers all use it.
- Time to tie
- ~30 seconds with a follow-through.
Bowline
- Ease of inspection
- Harder — looks similar to several incorrect variants. New climbers often misidentify a wrong bowline.
- Untying after a fall
- Easy — works loose almost immediately, even after a serious whipper.
- Reliability when tied wrong
- Variable — some bowline variants can capsize under specific load patterns.
- Backup knot required
- Yes — every bowline tie-in is finished with a backup (double overhand or Yosemite finish).
- Used in gyms
- Allowed at some gyms; banned or discouraged at others.
- Used outdoors
- Common among experienced sport and trad climbers, especially on harder routes where falls are frequent.
- Time to tie
- ~15 seconds, but adding the backup brings it back to ~30.
Figure-8
Default for everyone. New climbers, gym climbers, and almost all outdoor climbers should use the figure-8. The "hard to untie" downside is rarely a real problem — most falls do not weld the knot.
Bowline
Hard sport climbing where you fall on the rope frequently and want a knot that unties instantly between burns. Only after you have rigorously learned a specific bowline variant (Yosemite or double-loop) and committed to always backing it up. Many guides will not let you use a bowline.
Which to pick
Use the figure-8 follow-through. It is the safest, most-inspectable, most-foolproof tie-in knot ever standardised in climbing. The bowline is a legitimate option for climbers who project hard sport routes and want easy untying — but the upside is small and the failure modes are real. If you are reading this comparison to decide which to learn first, learn the figure-8.
