If you’ve ever been caught in a sudden mountain storm you know how fast the temps can drop and before you know it you’re in the middle of a hailstorm with hail and snow piling at your feet. And if you’re at all sweaty you also know how quickly hypothermia can set in unless you quickly get warm and dry. The Brooks-Range Ultralight Alpini Shelter 400 is designed for moments like this, when you need to quickly set up shelter from the rain or snow. This Alpini Shelter 400 will accommodate up to 3 or 4 people with packs and is a lightweight and fast system to get out of the elements. Use it for sudden storms, lunch breaks in the rain, or any other occasion when you long for the protection of a tent, but don’t have the time to set one up. With only four people inside, it warms up in less than 10 minutes. Condensation is kept to a minimum thanks to breathable fabric and generously sized vents.
