Lowe Alpine Attack Summit

Pros:

1. Can be used as a compression sack within your bigger pack (so-so performance).

2. Is VERY light (14oz) and folds into its own pocket to make a very small package for transporting in a larger pack.

3. Removable foam bivy pad.

4. Very water resistant.

CONS:

1. Very sloppy when it comes to carrying crampons, axe etc.

2. On moderate loads (10 lbs), the mesh shoulder straps tend to bind into a thin strip that cuts into your shoulders.

3. Pack tends to "sag" on your back. With no load lifters this is to be expected.

I would recommend this pack only for the minimalist. Fold it up (or use it as a compression sack) and stuff it in your larger pack for long approaches. Then pull it out for your summit bid. It generally feels great on your back until you throw your crampons and axe onto it... then it tends to feel awkward.

For strict dayhikes where I won't be carrying a large pack, I'll probably stick to my Alpine Attack 40. It compresses very well to daypack size, has a hydration pocket and carries crampons and axe better.

This pack's name says it all: Summit. It should really be used only as an ultra-lightweight summit pack, not a normal daypack. However, note that it is also intended for dual use as compression sack inside a larger pack on your way to high camp; just remove the foam back pad (make's a great seat) and use the three compression straps.

This pack is a real weight saver at high altitude when you don't want to lug your big expedition pack all the way to the summit. I've used it for this purpose on McKinley, Rainier, and Hood and been very happy to shave 6+ lbs. off my load. It is big enough to hold insulated clothing, food, water, a camera and a few gear items. But to save weight you do compromise on the shoulder straps (no padding), waist belt (1" webbing) and external lashing points (there is a small, single daisy chain for lashing gear).

The construction is good quality (I've always been happy with Lowe Alpine) and fairly robust although it is not intended for abuse day after day.
