Our Story

People ask us what X3SI means, or what it stands for. The three Xs are the basis of our existance, and our core offerings. Extreme Medicine, Experiential Education and Expedition Support. We off consulting, training, curriculum development, instructional design and expedition and event services, to clients spanning 4 continents, from many and various industries.

X3SI is uniquely positioned to help organizations move from traditional training delivery models to hybrid and flipped classroom delivery, while maintaining quality pedagogy and an experiential focus.

We worked with X3SI to move our two-day Risk Management for Outdoor Programs training from a classroom offering to a hybrid e-learning program, and we couldn’t be happier with the result. Highly recommended!

We provide standby medic services for both urban and wilderness  events, from first aiders, through to medical professionals, as required.

We offer training services for the general public and medical professionals alike,  including (but not limited to) urban first aid, wilderness medicine, travel medicine, off-shore medicine and emergency medicine.


The training industry as a whole has suffered immeasurably during the pandemic.

We specialise in creating flipped classroom learning experiences with virtualised experiential content, allowing your learners to keep up to date, until they can get to a face-to-face skills workshop.


We provide the equipment and expertise  to make your adventurous  inclinations a reality.

Whether your dream is to drive from Singapore to London, your first four-wheel driving adventure, a photographic trip, or to take a group of kids on their first nature walk, we provide the expertise, experience and equipment to make your dream a reality.


We do a lot of different things for a lot of different people, and have a global network of partners to help with the things we don’t currently have the time or people to do.
