Open mat FAQ
Common questions about Brazilian jiu-jitsu open mats in Finland — for visitors and for the clubs who host them.
What is an open mat?
An open mat is an open training session where practitioners roll (spar) freely, usually with little or no formal instruction. Many open mats welcome visitors from other clubs, making them a relaxed way to train with new partners.
Who can attend an open mat?
It depends on the club. Many open mats are open to visitors from other gyms and to all levels, while some are members-only or expect a minimum experience level. Check the session's tags (such as drop-in or visitors welcome) and the club's own info, and message the club first if you're unsure.
Is it free, and do I need to be a member?
It varies by club. Sessions marked "Free" cost nothing; others may ask for a small drop-in fee. You usually don't need to be a member to visit, but confirm with the host club.
Should I pay — and why do some open mats charge?
Hosting an open mat is real work: the club pays rent, and someone cleans and disinfects the tatami and changing rooms after every session. So it is completely normal, and fair, for a club to ask for a small drop-in fee — paying it, or buying a drink or some merch, is what keeps the mats open. If money is genuinely tight, most clubs would still rather see you train than stay home: just be an appreciative guest, support them however you can, and help keep the place clean.
Gi or no-gi?
Each session lists its style — Gi, No-gi, or both. Bring the right attire for the session you're attending.
What should I bring?
A clean gi and/or a rashguard and shorts for no-gi, a mouthguard, water, and flip-flops for walking off the mat. Trim your nails, and stay home if you have an infection or an open wound.
What's the etiquette at an open mat?
Arrive on time, introduce yourself, and ask before joining a roll. Tap early and honour taps, match your partner's intensity — especially with people you don't know — respect the host club's rules, and help keep the mat clean.
What does consent mean on the mat, and how do we keep each other safe?
Brazilian jiu-jitsu is an individual sport you can only practise together: every technique is trained on a real partner who trusts you with their body. That makes consent and mutual care the core etiquette. You can always decline or stop a roll — no explanation needed — and you should expect the same in return. Agree on intensity before you start, go lighter with anyone you don't know, mention injuries or big size differences, tap early and honour every tap instantly, and never crank a submission. Respect your partner's body and boundaries, and look after the person you're training with as much as your own progress.
How current is the schedule information?
Listings come from clubs and organisers and are reviewed before they go live. Schedules can still change around holidays or at short notice, so confirm with the club before travelling.
How do I add or edit my club's open mat?
Use the "Add a club" form to submit your club and its open-mat times; a moderator reviews it before it is published. After that, organisers can sign in to manage their own profile, schedule and editors.
Can I subscribe to open mats in my calendar?
Yes. Use the Subscribe button on the browse and city pages to add open mats to your calendar app. The subscription follows the filters you've applied, and each event links back to its page here.
