Hyperlite Mountain Gear Daybreak 17L Backpack

Daybreak 17L Backpack

Summit towering peaks, traverse dicey ridges, and squeeze in afternoon treks with Hyperlite Mountain Gear's fully-featured, ultralight Daybreak Backpack. Weighing barely over a pound, the Daybreak boasts a surprising 17L capacity suitable for a day's worth of food, water, layers, and even climbing gear. Hyperlite acheived such a phenomenal light weight by building the pack out of Dyneema, a material used in climbing gear for long-lasting durability.

Despite its light weight, the Daybreak is incredibly comfort, with padding at the back panel and shoulder straps, as well as a waist belt that stows away when you don't need it. The front pocket doubles as a hydration sleeve for your reservoir, and the internal sleeve doubles as a laptop sleeve for casual days. There's also a removable attachment system for ice axes or trekking poles, and a zippered internal pocket for valuables and electronics.

Great lightweight pack!

Durable, lightweight, minimalist!!

Do you know if this qualifies as a airline "personal item" and would it fit under an airlines seat?

Excellent Piece of Equipment

I've put it through the wringer

Took on a one week camping trip as soon as I got it. We day hiked every day with it. Super light and completely water proof. Layout is great and ability to store away hip belt is good too. Only concern point so far is minor abrasion on the bottom from setting down on rocks showed up immediately. Time will tell on the durability. If you’re looking for a top of the line waterproof and light weight pack this is IT!

Awesome pack

I've used it several times

Great combination of lightweight and comfortable with just the right amount of internal organization. Took this out on a hike along the Billy Goat Trail in Great Falls, MD with the kids. Pack comfortably carried hike essentials (1st aid kit, compass, GPS, etc) along w/rain jackets, and lots of water. 3 liter bladder fit fine in the interior pocket w hose extending thru main zipper. Used a framesheet from another pack to give more rigidity which helped shift weight to hips w/belt. Only downside: While Dyneema is great for most of the pack construction, it does make the back panel pretty hot (and sweaty). Not a huge deal, but probably won't be my serious hot weather pack.

Hey Joe! I'm glad to hear you're loving the pack! Thanks for contributing to our online community with the great review. Cheers!

Perfect for day hikes

I've used it once or twice and have initial impressions

I just took this on a 13-mile hike up Mt. Timpanogos and back, and found it to be the perfect tool for the job. The outside front pocket accommodates a 2L water bladder with ease, and the two side pockets hold another water bottle and/or whatever other small things you might need quick access to. There is one small inside zipped pocket for ID/cash, etc., another larger internal pocket, and otherwise there's just one large area which easily held two jackets (one puffy, one light), a first aid kit, a hat, and sunscreen. The pack itself is quite light and the chest and hip straps work great to keep it stable and in place.

Great daypack

I've used it several times

A well thought out designed backpack. It is not the cheapest backpack out there for a reason. It is just a great, very well made pack and I would buy again.


Considering getting this as a climbing leaders pack, is it durable enough to stand up to possible abuse in chimneys and such?

Hi Zach, great question! Dyneema is one of the strongest and lightest materials available for packs, 15 times stronger than steel according to HMG's site, so it should be up to the task!
