Announced at last years trade show Outdoor, the Alpha FL packs from the dead bird are finally available. Arc’teryx’s alpine pack line includes a 30L version and a 45L one but read on to know more about those deceiving numbers.
In Arc’teryx’s own classification Alpha is for climbing and alpine focus products. The FL in the Alpha FL means Fast and light. The other main characteristic of those two packs is the special fabric that was used in the conception. The N400r-AC² is a lightweight and impermeable nilon ripstop fabric, coated on both sides. The inside of the body is also pigmented white to reflect light and help with visibility inside the bag. That’s the kind of details Arc’teryx would add to its gear. The Alpha FL packs are also fully seam-sealed to make then truly resistant to bad weather. The main compartment has a roll-top closure system, independent from the expandable collar. This permits having a less fragile gear like a helmet on top, readily accessible. This is where the numbers are a bit deceiving. The Alpha FL 45 is actually 33L, maxing out at 45 with the collar extended, 23L being the base size of the Alpha FL 30.
Other interesting features include thermoformed shoulder straps, removable sternum strap, hipblet, formed back panel and two ice axe loops. Weight has been measured at 578g for the 30L and 660g for the 45L. Raf has a great review of the 45L one on his website The Alpine Start, check it out.
