4400 Ice 70L Backpack
The biggest difference between Hyperlite Mountain Gear's 4400 Ice Backpack and traditional expedition packs is the lighter weight, and that makes all the difference. At just over two pounds, the Ice pack holds enough gear for ski touring Alaska's Hayes Range or alpine climbing 14ers. Hyperlite Mountain Gear achieved a phenomenal weight-to-capacity ratio by building the backpack out of Dyneema, which is a rope fabric that climbers depend on when they're falling. This results in an ultralight backpacking that's built to last.
The Ice backpack's Dyneema Hardline suspension system includes an internal framesheet for sturdy support, spacer mesh padding at the shoulder straps and waist belt for breathable comfort, and removable aluminum stays for stability when you need it. Hyperlite equipped this pack with a roll-top closure and taped seams for protection against wet weather and snowy conditions. There's also an external attachment for crampons and ice axes, and a zippered internal pocket to secure small essentials and electronics.

Perfect for Mt Rainier
- I've used it once or twice and have initial impressions
I purchased the 4400 Ice Pack for a multi-day climb of Mt Rainier in May. I originally thought I could use my 3400 Ice Pack for this trip, but when you are 6'4" all of your "long" gear starts to take up too much space. I had no problem fitting 4 days worth of personal and team gear in/on the 4400 Ice Pack. I was surprised that it was actually comfortable on the first day carrying 55lb. I used a couple of pods to help with the organization and made it easy to find what I was looking for when taking breaks and then setting up camp. The best part about the entire line of Ice Packs is that the roll-top closure and compression straps allow you to transition to having an awesome summit pack.
