Pa'lante Packs
Pa'lante Packs V2
The Pa'lante V2 is the lightest pack in this catalog at 18.6 oz, and the clearest expression of the frameless ultralight philosophy: no frame, no stays, no lid, and a bottom pocket instead of a brain. It only works for hikers whose base weight is low enough that a frame is genuinely unnecessary.

Mountain Laurel Designs Exodus 55
The Exodus is Mountain Laurel Designs' 55 L frameless pack, offered in a choice of UltraGrid or Ultra X fabrics which is why the price runs from $245 to $325. At 1 lb 2 oz for 58 L of measured volume it has one of the best weight-to-volume ratios here.

Mountainsmith Zerk 40
The Zerk 40 is Mountainsmith's ultralight entry, using a recycled Extreema ripstop and a removable frame sheet so it can run framed or frameless. At 51 L of measured volume for a 40 L badge it is one of the more honest under-claimers in this catalog.
