Black Diamond Epic 45 Reviews:

Positive Reviews:

I'm 6'4 with a long torso, so I love the extra long length available in this pack. I was also pleasantly surprised with the weight of the pack; very nice given its size. There is a strap hidden in the top of the pack for carrying a rope, a nice touch that doesn't get mentioned. Also appreciate the single buckle to close. One less thing to do. Hip belt was well padded especially given the low weight, that was also an excellent surprise. I used to be all about the pockets but I have progressed to valuing lower weight over more pockets, so the single big hole on this pack works perfectly for me.
Its a little annoying that the top isn't floating (the back is fixed to the top of the main pack) but I don't think I will massively overload this pack so I am not too worried about it. Also the shoulder straps are a bit narrow around the neck area, but they seem to have known and accounted for that with different material there.
Overall I am extremely pleased with this pack and I will probably make it my go to winter backcountry pack for ice climbing/mountaineering. I'll also going to sell my Osprey Variant 37 and pick up the Epic 35 if I can find it for shorter days.

I never imagined that I would say this about a pack, but the BD Epic 45 is so comfortable that I plan trips just so I can have an excuse to use it. It's that good.
It is loaded with a ton of features. I notice something new every time I put it on (did you know there is a whistle built into the chest buckle?). To be honest, I doubt that most people who choose this pack, myself included, will ever use this thing to its full potential. It can do almost anything that could be expected of a pack. Most importantly, it will keep you comfortable and on your feet no matter where you are or what you are doing.
If you have yet to try out a BD pack designed with the ErgoACTIV system, do so. You will be impressed. The way it distributes the weight of the load and allows your torso to move freely is incredible. After using this pack, I can't believe I was satisfied with anything else.
I'm a medium sized guy, 5'10", and the medium fits me superbly well. Great fit, easily adjustable, amazing pack overall. Oh, and that Cobalt blue is BLUE. Still loving it.

Great pack, one minor issue

Did an overnight snow route in Colorado with this pack. Very comfortable and effective. The swivel hip-belt is a very nice touch. The overall design of the pack distributes a decently heavy load nicely. You can pack this thing to the gills and not have to worry about over-doing it. Durable and user friendly, yet simple without too many bells and whistles. Really liked the ax holders. Would have given this pack 5 stars, but the zipper on the top of the lid would not zip closed - faulty zipper design. Going back to try and find one of these packs without this defect. I highly recommend this pack for alpine/snow climbs and general mountaineering, BUT do NOT order online. Go to the store and make sure that all of the zippers work properly.

Almost worked for me

I wanted to love this backpack. It seems well made and the unique suspension system intrigues me. I purchased it with mountaineering in mind. The trouble I had with it was the lack of adjustability. I am somewhat tall and slender (6' tall, 30" waist), and the torso length of these packs cannot be altered. The waist belt of the Medium fit well, but the torso was too short. Bumping up to a Large improved the torso fit, but then the waist belt was too big to cinch down and ride my hips properly. Had to return it.
I like the streamlined simpleness of the backpack. The ice tools pocket might be a good thing for technical climbers - I would have preferred a couple of simple ice axe loops.

I recently used this on a backpacking trip on the Superior hiking trail . It was the 1st time useing this backpack. I was caring about 30 pounds for 4 days on the trail. The epic 45 was amazing I own few different backpacks Out all of them this is by far the best . We hike for about 10 hrs a day i never had any sore spots I dint ever have to adjust the straps with the ergoactiv system it was great on scrambles with the amount of movement that you have and no pain at the end of the day I highly recommend this to anyone ...

The Black Diamond Epic backpack exceeds the functionality of the Black Diamond Infinity 60 backpack for faster lighter climbs and true minimalist gear loads. On any other occasion I use the Infinity 60. The Epic is also 4 season pack and very durable. For me this is essential as I've been hiking and climbing for about fifty years and I don't like re-buying gear. I also want gear that I can depend on. If you get a chance try one out at a store. Pack what you'll be carrying and see how it feels. That's always the best way to go about choosing a pack.

John Roorbach at on 09/02/2011

I first saw the Ergo-Active thing and went... wha?
Tried it on, and was like... WOAH.
Scrambling sketchy 4th class with a pack on can be scary, but this thing moves with you like no other pack can, keeping your center of gravity from dramatically shifting and throwing you off balance. The material feels super burley, and the fit is very comfortable on my back. The 45 has a very long torso which was kind of strange on me (I'm 5'10" with weirdly long legs and a shortish torso), but the 35 feels awesome.
Big fan of the rope strap/lid, holds a rope great.

Thomas Ogasawara at on 05/06/2012

This pack has been on many many alpine and ice climbing trips. My workhorse for sure. Most of the time I only need 35L, but the extra 10L has come in handy now and then. The Crampon patch works great, and the ice axe holders are the best I've used. I wish the lid floated, but it's not bad, the two pockets in the lid are great to keep things sorted. Super comfortable even on extended day long alpine climbs. Everything stays secure and comfortable on shoulders, back and hips.

Ryan Hamilton at on 04/04/2013

This is by far the best climbing pack I have had so far. I've been through an EMS 2800, and a Cold Cold World. Recently did a long alpine route in the White Mnts and boy what a great thing the ergo-active is. From high angle post holeing to vertical ice it didn't feel like I had a pack on at all. The only comment so far is the frame makes it a little tough to climb vertical, hard to look up without the pack pushing the helmet forward.

The crampon strap and pick pocket are handy features, but what makes this pack shine is the ball joint belt connecter and swing-arm shoulder straps. The weight of the pack stays in your center of gravity when leaning and reaching. For me, the pack is extremely comfortable. Many will find the lumbar pad odd feeling or uncomfortable. It's one of those "love it or hate it" things.

Negative Reviews:

* sooo cool color. Sooo cool look. Soooo good to leave at home
* rope strap buckle broke in my hands at trailhead
* I had to unstitch a hydration port joint a little to pull out Platipus drinking tube
* shoulder straps are too sharp and uncomfortable
* waist belt attachment hurt my back badly in 3 days
* hydration port somehow was blocked when the pack was closed. The only way to hydrate was to open the top lid
Resume: get 2010 Black Diamond Speed and replace velcro ice tools straps with something more reliable (e.g. 6-8" of 4-5mm cord).
