Your climbing journey starts here

​"I want to make climbing accessible, simple, and above all, fun for those of you who have just started."

​Welcome to Bsori!

​I started this site because I know exactly what it’s like to be brand new at the gym. My goal is to lower the barrier for you by gathering everything I felt was missing when I started:

  • ​Auto-belay climbing and the basics of bouldering: Concise info to get you up on the wall quickly.

  • ​Honest reviews: I check out clothing and gear that actually work.

  • ​Exclusive discount codes: Gear up for climbing without breaking the bank.

​Who am I?

​My name is Per Anders, a Södermalm local who has become completely hooked on the world of bouldering.

​Right now, you’ll usually find me at Moumo two days a week. There, I wrestle with both tricky bouldering problems and my own fear of heights—a challenge I share with many! But I’m not stopping there. In 2026, a new chapter awaits: I’m going to truly challenge my fear of heights by starting with auto-belay at Klätterverket Sickla.

​"Why Bsori?"

​The name is a mashup of my two biggest passions: Bouldering and Sori.

​For those not local to Stockholm, "Sori" is our shorthand for Söder om Ringvägen—the vibrant neighborhood on the southern tip of Södermalm. Bsori.se was born from the idea of blending the grit of the climbing gym with the unique pulse of my home turf. It’s where chalk dust meets city streets.

Conquering My Fear of Heights – My Goal for 2026

​The world’s tallest climbing tower in Lillesand, Norway, stands at a staggering 47 meters. To some, it’s a dream; to me, it was an eye-opener. I’ve decided that I will no longer let my fear of heights set my limits.

​My big goal for 2026 is to conquer 12 meters at Klätterverket Sickla. When I reach that summit, I’m going to tell myself: "I am done with my fear of heights." That will be the starting point for a new journey, filled with exciting new challenges in the world of climbing.

Review: Highballer Shorts

​Kicking off Saturday with some bouldering and taking the opportunity to review the Highballer shorts.

​They are very roomy (I went with size L in the color Umber Brown). The organic cotton fabric is thick and durable, yet I feel like I can move completely unrestricted while on the wall.

​Perfect for bouldering.

Review: Rúngne Slab Tee – Untamed Spirit

​I’m really impressed with the Rúngne Slab Tee Untamed Spirit. The fit is excellent and it sits exactly how I want it to. What really stands out is the thick cotton—it doesn’t just feel incredibly soft and comfortable against the skin, but it also gives off a real sense of high quality and durability. I think it’s going to last a long time, which is perfect for climbing where gear really gets beaten up.

​Another big plus is that the heavy material keeps me warm during chilly mornings at the climbing gym, making it ideal for both autumn and winter. Overall, this T-shirt definitely lives up to the hype—stylish, comfy, and rugged. I highly recommend it!

Review: Magball

​I’ve been using the Magball as a refillable chalk ball in my bucket, and I’m really impressed with how it works. As a climber, I know how crucial it is to get just the right amount of chalk, and the Magball definitely delivers.

​Every time I give it a squeeze, I get exactly what I need—not too much, not too little. It keeps the mess to a minimum and makes sure my grip is always on point. The fact that it’s refillable is a huge plus too, since it saves me money in the long run.

Climbing with Auto-Belay: Your Guide to Solo Climbing

Auto-belay systems have revolutionized climbing gyms worldwide. They make climbing accessible to everyone, whether you are a beginner or a pro looking to crush some intervals. However, with this freedom comes a great deal of responsibility for your own safety.

Things to Consider Before You Start (Safety First!)

When there is no one else holding the rope, you are your own belayer. Here is the golden checklist:

 * The Self-Check is Sacred: Since you lack a partner to perform a buddy check, you must be twice as thorough. Is your harness fitted correctly? Is the carabiner properly locked into the harness belay loop?

 * Weight Matters: All machines have a minimum and maximum weight limit (often approx. 10–120 kg). Ensure you fall within this range.

 * Check the Path: Never climb directly under or right next to someone else. Also, ensure your fall line is clear of obstacles so you don’t land on anyone (or anything) on your way down.

 * Test the Load: Before going high up, sit in the harness about a meter off the ground to verify that the machine engages and lowers you smoothly.

 * "Forgetfulness" is the Biggest Risk: The most common accident scenario is starting a climb without clipping in at all. Always look up and confirm the webbing is attached to your harness before your feet leave the floor.

Gear: What Do You Need?

The beauty of auto-belay is that the gear list is short and simple.

Equipment  Why? 

  1. Climbing Harness Your most vital link to the machine. Ensure it is approved for sport climbing and fits snugly over your hips. 

  2. Climbing Shoes To get grip on small holds. For beginners, a comfortable all-round shoe is more than enough. 

  3. Chalk Bag  To keep your hands dry. During intense auto-belay sessions (where you often climb many routes in a row), you’ll get sweaty fast. 

  4. Comfortable Clothes  Focus on mobility. Pants that cover the knees can be nice to avoid scrapes against the wall. 

​A Beginner's Guide to Bouldering

​1. It’s a "Vertical Puzzle"

​In bouldering, a climbing route is called a problem. This is because it’s not just about raw strength; it’s just as much about technique and problem-solving. You need to figure out the sequence of hand and foot movements required to reach the top.

​2. How it Works in Practice

  • ​Color Coding: Each "problem" consists of holds in a specific color. You can only use that color for both your hands and feet.

  • ​Start and Finish: There are often markings (tape or signs) indicating where to place your hands to start. The goal is usually to hold the final grip at the top with both hands for a few seconds under control.

  • ​Difficulty Levels: Climbing gyms use different scales (often color systems or the V-scale) to indicate difficulty, making it easy to find a challenge that fits your level.

​3. Minimalist Equipment

​One of the biggest advantages of bouldering is that you don’t need to buy expensive gear to get started:

  • ​Climbing Shoes: These are tight-fitting with a special rubber sole for grip. You can almost always rent these at the reception.

  • ​Chalk: Used to keep your hands dry so you don’t slip off the holds.

  • ​Comfortable Clothing: A T-shirt and a pair of flexible shorts or leggings are all you need.

​4. The Social Aspect

​Bouldering is incredibly social. Because the walls are low and you spend a fair amount of time resting between attempts, people often sit on the mats and chat. It’s perfectly normal to ask someone for tips—known as "beta"—or work together to solve a tricky section.

​Three Quick Tips for Your First Session:

  1. ​Use Your Legs: The most common mistake is trying to pull yourself up with your arms. Your legs are much stronger—try to "stand up" into the movements.

  2. ​Straight Arms: Try to hang with straight arms while resting or planning your next move. This saves a massive amount of energy compared to keeping your arms bent.

  3. ​Learn to Land: Practice jumping down in a controlled way. Land with both feet simultaneously and roll backward if necessary to absorb the impact.

    4. ​Important to remember: Everyone at the gym was a beginner once, and the climbing community is known for being very welcoming. No one will judge you for falling off—that’s just part of the sport!
