The Bridger 65L backpack features a traditional travel bag design but has more storage space for gear and is also breathable strong frame and support. Adjustments and fine tuning of the clamp year after year have brought Mystery Ranch to this current version where it is now more comfortable and ventilated than ever so we can avoid dampness and discomfort during long days of trekking in remote places. Bridger also features a dual access main compartment so we can easily grab items without having to dig through everything. We like it that the removable cover can be used as a fanny pack for fun side missions during long multi-day excursions.
