Choosing a climbing harness.

Instruction comes first

The UIAA, in a 2018 handbook extract, says anyone using technical climbing gear needs to read its instructions, get specific training, understand its limits and accept the risks, and warns that failing to do so may result in severe injury or death. Fit, tying in and checking a harness are part of that training. Nothing here says a harness is certified, safe or fit for use; it explains what a marking means according to the body that defines it.

The standard and the four types

The European harness standard is EN 12277:2015+A1:2018; the Estonian standards body lists the consolidated version as valid from 3 January 2019. The UIAA's matching standard is UIAA 105, at version 4 (2018). Edelrid, a maker, says UIAA 105 adds no requirements worth mentioning beyond the EN standard; that is Edelrid's assessment.

SATRA, a UIAA-accredited test laboratory, summarises EN 12277 as defining four types, and Edelrid's summary of the standard describes each:

What the laboratory tests measure

SATRA's summary says EN 12277 loads the complete harness on a test dummy at each attachment point, upward at 15 kN or 10 kN and downward at 10 kN or 7 kN depending on type, each held for about 1 to 3 minutes, after which straps may slip through buckles by no more than 20 mm. It also sets minimum strap widths and requires stitching that contrasts with the webbing. Edelrid adds the pass criteria that no load-bearing part tears and the dummy is not released.

These figures are what a new sample must withstand in a laboratory. They are not a guide to what anyone may do with a harness. The UIAA notes, in an undated foreword to its inspection recommendations, that a standard sets a baseline on new equipment while field conditions and the gear's state matter just as much.

Reading the label

As Edelrid summarises EN 12277, a harness must be marked with the maker, the year of manufacture, EN 12277 and the type, how the buckles and adjusters work, a reference to the user manual, the size (and for Type B the weight range), the warning that Type D is not a stand-alone harness, and the CE mark with the notified body's four-digit number.

The European Commission's PPE guidelines (October 2025) name harnesses for mountaineering as personal protective equipment and place protection against falls from a height in Category III, for which the CE mark must be followed by the notified body's number. The Commission says the CE marking shows the product complies with EU law after the prescribed conformity assessment, and that voluntary certificates are not accepted as proof of compliance. In Great Britain, the UK government says CE marking is recognised indefinitely under regulations in force from 1 October 2024, so a harness may carry CE or UKCA marking.

Our picks by category

Lifespan: what makers say, and where they differ

Under Regulation (EU) 2016/425, makers must state a period of obsolescence where one applies, and the Commission's guidelines give "harness after fall" as an example of obsolescence set by an incident rather than a date. Makers' own statements differ:

• Beal (2019 notice): up to 5 years of storage before first use and a potential 10 years in use, 15 years in total, stressing that inspections decide earlier retirement. It lists a heavy fall even without visible damage, damaged webbing or stitching, buckles not working well, contact with harmful chemicals, or any other doubt as reasons to retire a harness.
• Petzl: quoted in search snippets of a 24 January 2018 article as giving 10 years for its plastic and textile products. The page did not open for our research, so this is unconfirmed.
• Black Diamond: credited in search snippets with a harness life expectancy of about three years depending on use, and retirement after ten years even if properly stored. Black Diamond published a QC Lab article on worn belay loops and retiring a harness on 27 March 2025, but our research could not read it, so these figures are unconfirmed.

Each figure is that maker's statement for its own harnesses, not a rule for all of them. The maker's instructions and a competent person decide when a particular harness is retired. Beal's 2019 notice also says harness storage or use must not exceed 80 C, and that a dirty harness may be washed in clean cold water at no more than 30 C; those are Beal's care statements for its products, and the gear care page compares makers.

Recent recalls

• The UIAA relayed on 28 February 2025 Black Diamond Equipment Europe's recall of the Black Diamond Vision Harness (style BD651096), all sizes made and sold from 1 January 2018 to 26 February 2025, which the maker linked to premature degradation of its materials and construction.
• Health Canada published on 14 May 2026 a recall of certain Petzl SIMBA and SWAN full-body harnesses sold from July 2021 to November 2025, because a missing rivet in the buckle could let it open. It reported no incidents in Canada or the US as of 13 May 2026.

The maker's own current notice is the authority on which products are affected; see recalls.
