ULA Equipment Photon

The ULA Equipment Photon is a frameless ultralight backpack built around a 35-liter total volume (20 L main body plus 6.6 L in the roll-top extension), designed for thru-hikers running lean base weights. At 740 g it sits in the featherweight bracket for full-size packs, working out to roughly 21 g per liter of carrying capacity — a ratio that reflects the frameless, unstructured build rather than a heavily engineered suspension. Construction uses 400 Robic Nylon ripstop with a PFAS-free DWR finish, paired with a contact-padded back panel instead of a rigid frame. Load transfer relies on the padded hip belt with pockets and a single chest strap rather than load lifters, so the Photon is best matched to loads the frameless design can still carry comfortably rather than heavy multi-week resupply stretches. One front pocket and two side pockets, hydration compatibility, and an ice axe loop round out the feature set. It suits thru-hikers and multi-day trekkers chasing a sub-kilogram pack who are willing to trade frame support and organizational pockets for weight savings, with unisex sizing keeping fit adjustments simple.
