Consumer Contract Regulations (CCR)

What are the Consumer Contract Regulations?

Under the "Consumer Contract Regulations, you have the right to cancel an order for goods made at a distance. These rights start from the moment you place your order and ends 14 days from the day you receive your goods.

Your right to cancel

Your right to cancel an order for goods starts the moment you place your order and ends 14 days from the day you receive your goods.

This 14 day period is the time you have to decide whether to cancel, you then have a further 14 days to actually send the goods back.

Your Right to a Refund under CCR

You may get a refund within 14 days of either, the trader getting the goods back, or you providing evidence of having returned the goods (for example, a proof of postage receipt from the post office), whichever is the sooner.

A deduction can be made if the value of the goods has been reduced as a result of you handling the goods more than was necessary. The extent to which you can handle the goods is the same as it would be if you were assessing them in a shop.

Refunding the cost of delivery

The trader has to refund the basic delivery cost of getting the goods to you in the first place, so if you opted for enhanced service e.g. guaranteed next day, it only has to refund the basic cost.

Exemptions

There are some circumstances where the Consumer Contracts Regulations does not give you a right to cancel. These include CDs, DVDs or software if you've broken the seal on the wrapping, perishable items and tailor-made or personalised items. They also include goods with a seal for health protection and hygiene reasons that have been broken or tampered with, e.g. Climbing Equipment and PPE.

My goods are broken

If you feel that your item is defective/broken/faulty and it is still under warranty, please contact our Customer Support team([email protected])with as much information as possible with regards to the fault, including photos if applicable.

We want to reduce our impact on the environment as much as possible, the first step for this is reducing our waste. Therefore, please note that we will always offer a professional repair in the first instance; if the product can be repaired.

This may involve your product being sent back to our suppliers or to a professional repair company. Please note that due tovaried procedures, warranty claims and repairs can take between 2 and 4 weeks to be concluded

Black Diamond Mens Solution Harness Carbon

Season:SS26

Brand:Black Diamond

Code:BD651120-0003

All-Day Comfort for Every Stage of Your Climbing A reliable, do-it-all climbing harness built to support you from your first sessions on the wall to long days on real rock. The Black Diamond Solution balances lightweight performance with genuine all-day comfort, making it one of the easiest harnesses to recommend, especially if you want something you can grow into. Whether you’re training indoors, projecting sport routes, or heading out on multi-pitch trad climbs, it delivers the comfort, durability, and simplicity you need to focus on climbing, not your kit.

What is the Black Diamond Men’s Solution Harness?

The Black Diamond Men’s Solution is a high-performance climbing harness designed for versatility and lasting comfort. Suitable for sport, trad, and gym climbing, it features a Contour Edge waistbelt and leg loops that blend supportive structure with soft, tapered edges to reduce pressure points. This ergonomic construction allows the harness to move naturally with the body while maintaining a secure, stable fit.

What is it made of?

Premium Material Mix

The Solution Harness is engineered from a balanced combination of advanced fibres, foams, and reinforcements to ensure durability, structure, and comfort. Polyester and nylon fabrics form the outer shell, providing abrasion resistance, breathability, and flexibility. EVA foam offers lightweight cushioning and even pressure distribution across the waistbelt and leg loops, while internal nylon webbing provides tensile strength and maintains the harness’s shape over repeated use.

UHMWPE fibres reinforce high-stress zones such as the belay loop and tie-in points, delivering exceptional strength-to-weight performance and resistance to wear. Aluminium hardware enables secure, lightweight adjustments, and urethane tubing enhances durability at connection points. Together, these materials create a harness that is resilient enough for demanding routes yet soft enough for long hanging sessions.

Fusion Comfort Technology Construction

The Solution Harness uses Black Diamond’s Fusion Comfort Technology, which incorporates three low-profile webbing bands into the waistbelt and leg loops. This distributes pressure evenly across a broader surface area than traditional single-band designs, eliminating hotspots and improving fit. The result is a supportive yet flexible harness that contours smoothly to the body and remains comfortable through dynamic movement or extended belays.

What are its features?

Ergonomic Performance Fit

The men’s-specific proportions and balanced rise provide a secure, body-contouring fit that stays comfortable during high steps, bridging, or hanging belays. Pressure is distributed evenly to prevent pinching and hotspot formation, supporting all-day sport or trad climbing comfort.

Contour Edge Comfort

Contour Edge technology ensures the waistbelt and leg loops remain supportive in the centre while tapering into softer edges. This reduces digging and chafing, allowing natural movement and a lightweight, unobtrusive feel during climbs.

Efficient Racking System

Four large thermoformed gear loops maintain their shape for easy clipping and organisation, accommodating up to 15 quickdraws per side. A low-profile fifth rear loop provides extra storage for accessories or a belay device without interfering with a chalk bag.

Infinity Belay Loop

The seamless Infinity Belay Loop removes stitching and potential weak points, offering enhanced durability, smooth handling, and long-term reliability for belaying and rappelling.

Adjustable Elastic Risers

Releasable rear elastic risers allow quick fine-tuning of leg loop tension, maintaining mobility for high steps and wide stances while keeping the harness properly positioned. Quick-release clips add convenience during multi-pitch use.

Features:

  • Ergonomic men’s-specific proportions and balanced fit
  • Fusion Comfort Technology for even load distribution
  • Contour Edge waistbelt and leg loops for superior comfort
  • Four large thermoformed gear loops plus low-profile rear loop
  • Seamless Infinity Belay Loop for long-term durability
  • Adjustable, releasable elastic risers
  • Lightweight, breathable construction for all-day use

Black Diamond Solution Harness Review If someone asks me to recommend a first ‘proper’ climbing harness, this is usually the one I point them to. The Black Diamond Solution hits that sweet spot between comfort, performance, and simplicity. It’s easy to live with, comfortable from the first tie-in, and capable enough that you won’t outgrow it as your climbing progresses. Thanks to Fusion Comfort Technology, pressure is spread evenly across the waist and legs, so whether you’re taking your first falls or working a project, it stays supportive without becoming distracting.
Comfort You Notice On Long Sessions The Solution really comes into its own once you’ve been tied in for a while. Fusion Comfort Technology uses multiple low-profile webbing bands to distribute load across a wider surface area, reducing pressure points during hangs and belays. Contour Edge construction keeps the core supportive while softening the edges, and lightweight EVA foam adds cushioning without bulk. The result is a harness that feels comfortable early on and still feels good when your forearms are done, but you’re not ready to call it a day.
Grows With Your Climbing What makes the Solution such a safe recommendation is how well it adapts as you progress. It’s light enough for hard sport climbing, supportive enough for long multi-pitch days, and durable enough to handle regular gym sessions. The seamless Infinity Belay Loop improves longevity and rope handling, while four large thermoformed gear loops plus a low-profile fifth rear loop cover everything from quickdraw-heavy sport routes to trad racks. At 378g, it’s a harness you can rely on without feeling weighed down.




FAQ

Is the Solution a good harness for beginners?

Yes, it’s one I regularly recommend to people just getting into climbing. It’s comfortable straight away, easy to use, and versatile enough that you won’t need to replace it as soon as you start pushing grades.

Will I outgrow it as I get better?

Unlikely. The Solution is just as happy on steep sport projects and long outdoor routes as it is in the gym. It’s designed to progress with you.

How does it feel when you’re hanging around on the rope?

Surprisingly comfortable. Fusion Comfort Technology spreads pressure evenly, so it doesn’t dig in during rests, belays, or repeated falls.

Is it practical for everyday climbing sessions?

Very. It’s lightweight, breathable, and quick to adjust. Making it ideal for regular gym visits, training sessions, and after-work climbs.

What about gear storage?

Plenty of space. Four rigid gear loops keep things easy to clip and unclip, with a fifth rear loop for accessories or a belay device.

What makes the belay loop different?

The seamless Infinity Belay Loop reduces wear points and offers smoother rope handling, improving durability over time.

If I only want one harness, is this a safe bet?

Absolutely. It’s comfortable, versatile, and dependable, a solid choice whether you’re just starting out or climbing 9a.
