The Tom Bihn Tri-Star is a mid-size carry on travel bag designed for short trip. It’s size is designed to meet all airline carry on size regulations (including the stricter carry on regulations in Europe and Australia).   I typically use it for short trips of one to three days.

As the “Tri” in it’s name implies the bag is designed around threes:

• The Tri-Star has three main compartments of approximately equal size. The front compartment can be further divided left and right, with a zip out divider.
• On the left side are three horizontal zippered pockets. The top zippered pocket spans the full height of the bag; the second goes about half way; and the third is the shallowest of the three.
• Three ways to carry it – Padded Suitcase handles for carrying down narrow aircraft isles, Padded (and stowable) backpack straps for longer hikes, and metal attachment rings for a shoulder strap (the Tom Bihn Absolute Strap is a $30 add-on)

The front has an additional curved pocket on the right–I use it to stow my boarding documents. It can be used for stowing a water bottle as well. Read more »
