That’s right, a backpack from Big Sky International. The new Shadow Pack, available in spring 2008, is a 4000 cubic inch (65 L) internal frame pack weighing just 2 pounds 15 ounces. The distinctive features that set it apart (besides its light weight) are its durable Dimension Polyant VX21 fabric, top and panel access, and well-padded suspension system. The full feature set is listed below.

Big Sky’s new Shadow backpack hits the sweet spot for lightweight backpacking with a simple internal frame (two vertical aluminum stays) and 4000 cubic inch volume. The fabric is Dimension Polyant VX21, which is very durable. The backpanel side (right) of the pack shows its well padded suspension system and optional hipbelt pouch. The hipbelt is a full 5.5 inches high and well padded; shoulder straps are 3 inches wide.

The Dimension Polyant VX21 used is a sophisticated three-layer fabric, consisting of a strong abrasion-resistant nylon face fabric, a diamond pattern of reinforcing polyester threads (visible in the pictures), a layer of permanent adhesive, a layer of non-stretch mylar film, another layer of adhesive, and finally a layer of light fabric on the inside surface to protect the mylar film. The outer face has a good DWR treatment as well. The fabric, which weighs 204 grams/square meter, is essentially utterly waterproof, although seams can leak through the needle holes.

That looks like a great pack! Seems like it has a great compression system which is what I always find lacking in lighter packs.

Tough fabric is nice. I would prefer for it to be a bit smaller, but 4000ci can work for winter I suppose!

I would love to try this pack out!

BIG SKY… Nice Pack!

2lbs 15oz's like Andrew mentioned looks perfect for winter travel or for long unsupported treks. I also appreciate the extra durability

How does it compare in volume and carrying to a GG Nimbus Ozone?

Don't worry about it - not like you will ever see one after you order it, or at least within 12 to 16 months.....;)
