Mountaineers/hikers: I have an insurance question before a trip to Georgia

Okay, it's not me traveling but I want to help anyway, and so I turn to you.

A group of good friends from Denmark are going to climb mountains in Georgia, so they need insurance that covers helicopter rescue.

However, they complained that the insurance companies they have contacted are intentionally very vague in their wording, and as the trip is around the corner, I thought I'd ask reddit what you recommend in this situation.

Does anyone know of a reliable website that compares coverage and prices for international travel? Are there any insurers that you know include this type of rescue?

Thanks!
