Ships in 1-2 business days | Based in Biddeford, ME | Est. 2010Hyperlite Mountain Gear's most versatile, long trail pack *Formerly known as the "3400 Junction"The versatile Junction 55 allows you to keep your options open when it comes to packing for a big weekend, multi-day section hikes, thru hikes, or to meet the gear demands of changing seasons and environments. Ideal when resupply points are less frequent and/or for equipment flexibility is needed. When the extra volume is not in use, the 55's top can roll down enough to make the overall size of the pack similar to the 40, but that additional space can come in pretty handy when you need it.For hikes measured more by changes in climate zones and geographical features than distance, the Junction offers the ultimate versatility required to meet those demands.Features:Internal Frame + Padded Hip Belt.One external center mesh pocket with two solid-panel Hardline with DyneemaA(R) pockets on the sides - dry gear faster with the middle pocket, protect or hide items in the sidesRoll-Top closure system with side compression straps for vertical compressionTop Y-strap compressionSide compression straps for horizontal compressionZippered hip belt pocketsAdjustable sternum strap with self-tensioning elastic and whistleInternal 8" x 14" mesh sleeve for hydration bladderIntegrated 1/4" foam back panel padTwo removable, contoured aluminum staysFour exterior triglide buckles for optional pack accessory strapsGrab Loop & Ice Axe Loop_______________________________________________Specs: Volume: 55L (3400 cu. in.) main bodyExternal: 9.8LDimensions: 34"H (fully unrolled) x 10.5"WCircumference (Top | Bottom): 40" | 33.5" Frame: Integrated 1/4" foam back panel pad, 2 removable aluminum staysHipbelt: Integrated padded with pocketsRecommended Maximum Load Capacity: Up to 40lbsSizing:Small: 15"-17" torsoMedium: 17"-19" torsoLarge: 19"-21" torsoTall: 21"+ torsoWeight: 31.9oz (White in size medium), 34.4oz (Black in size medium)Materials: Body: DCH50 Bottom: DCH150External Pockets: DyneemaA(R) Hardline Shoulder Straps & Hipbelt: Hardline with DyneemaA(R), Closed cell foam, Spacer meshMade in Mexico_______________________________________________Ideal for: Backpacking & Thru-hiking in any environment
