Unbound 55 is the best!

It's well made, so it's comfortable to carry heavy items on your back.If you remove the frame and waist belt, it weighs 650g.This is very convenient when you don't have much luggage, such as in the summer.

So far so good.

Took out for 8 miles yesterday and liked using it. Excited to tinker with how I can pack/utilize it best.

Instant success

Having used a competitors ultra light weight pack for adventure racing and hiking for several years I decided that the issues that I had with the pack were finally worth addressing. The Inbound 55 harness fits like a glove and remains comfortable at the end of multiple 10+hour days in a row. The side pockets are easily accessible on the move and the rear pockets are robust and offer an innovative way of dealing with the various items that you need quickly without the need to delve into the pack. Delighted with the Unbound 55. Thoroughly recommended.

Great Pack!

I bought this pack for my husband and he loves it. He especially loves the gear sleeve/pocket on the bottom and overall durability of the pack. The stretch pocket on the front is great and a very durable material that he won't have to worry about easy tears. He had some issues with the size and were able to get great customer service and get the right size. He is very excited to be using it on our upcoming Appalachian Trail thru hike attempt this year. Thanks Hyperlite!
