    Ursuit suits are popular here in Scandinavia as a good drysuit at a medium price point. The heavy/light line is similar to a TLS in material. There are cordura suits as well as the kevlar if you need...

    And if you add sumps there are even more. Also we have mines which, in swedish conditions, I would argue are more or less the same as cave diving in everything but the name. The skills are the same...

    I honestly don't think it's that much of a problem getting to the Tulum area even if you're staying in one of the hotels. I've mostly been staying in Tulum for convenience but at times I've brought...
