Drycomp Summit Sack™

Style# 36603OR

This ultralight and waterproof day pack has all the features needed for a fast and light summit push. An airpurge strip allows for maximum compression, as the air-permeable fabric allows the complete evacuation of internal pressure. Sewn and taped seams, and reinforced fabric on the bottom and back area provide maximum strength and waterproofness. Mesh side pockets accommodate water bottles, and gear loops secure ice tools. Compression straps cinch down your load, and padded shoulder straps combine to offer a comfortable fit for alpine climbing and peak bagging.

Dry bag pack, that packs in a carry on bag (Review by bozowest)

I love this pack and have bought many as presents. It keeps the rain out and is very lightweight. I ball it up and pack it with me in my carry on for business/pleasure trips. This way I always have a convenient pack for bike rides, hikes or shlepping groceries. I have taken it on river trips, mountain hiking and around town. I would add a loop inside to attach a biner for keys and other items . Also, I took it climbing and when ducking under a juniper branch tore a large gash in it, so it isn't indestructible, but that is the price for minimal weight. Get and OR zip sack to store your small stuff inside this dry bag.

Just wow!! (Review by Nicolas)

My new best friend during my 2 months trip in Nepal and India. Daily use and a daily satisfaction.

Great little Sack (Review by deMag)

Perfect for daily use, great by the water, lightweight and versatile. Took it for a holiday in Australia, the Brits on our ferry to the Great Barrier Reef wanted to know where to get such a great dry bag, and our daughter is keeping it to use on her morning commute especially in the wet season there.

A commuter's dream. (Review by mountainchildva)

Okay, I have to admit, I use this bag as my daily commuter bag. I need to carry my work clothes each day as I workout then go straight to work. This bag is perfect! It's totally waterproof and comfortable to wear. I was initially worried since it has no interior pockets, but I use a zip sack to carry my keys and other junk, and it works great. I'm tough on my gear, and I've been using this a few months now with no issues whatsoever.

Light but not durable (Review by Hunter)

Very light and packable. I liked that it was waterproof and thought it might work well for canyoneering (where you often have chest deep pools to wade through). The bottom and sides had holes in them and one waterbottle pocket ripped out by the end of a 12 rappel slot canyon in Zion (Spry Canyon), likely from brushing up against walls and the occasional steming. Serves its purpose for summit bagging if non-technical, but would likely not stand up to alpine scrambles either
