Bad fit

  • Familiarity: I've used it several times

I love Osprey, and I have another pack from them (aura 65) which is amazing. After looking at the sizing chart, I got an XS (which matches the XS measurements for the Aura), but the size is very different. The length of the back is much smaller. If I adjust the straps correctly, the belt ends up on my waist. If I adjust the belt correctly, the straps are way too long and they strain my shoulders.

When I initially tried it on (flat with no weight) it seemed great, so i took off the tags. Now that I have taken it on three trips with various weights, its clear that I can't wear this backpack for anything more than a couple of pounds. What a shame! I've been saving up to get this pack for a while, and now it turns out to be unusable :(

Hi Alena, I am so sorry you are disappointed with this. The belt is designed to fit higher than a large pack, like the Aura. For that pack, having the weight on your hips is important. For the Mira, a bit above that is totally OK. I am wonderng if allowing the pack to ride a bit highter than you think it should would help out? I really hate hearing that you are bummed out!

Have a great New Year,

Hey Leta,
It sits on my natural waist and it's hard to breathe with it on if I'm hiking up. I have a Gregory Jane 34L which is a bit too big in the waist, but it definitely sits more comfortably. This Osprey was meant to replace it :( I wasn't carrying too much load in it (my harness, personal gear, shoes, helmet, food, hydration pack) and it strained my shoulders a lot. I think its because it is pretty short but expands pretty far back keeping the load a bit far from the back. I've seen some really good reviews, but just seems like its not for tall skinny people. I'm exchanging it for the Strata, hope it will do better!

Amazing Day Pack

  • Familiarity: I've put it through the wringer

I love this pack. I've taken it on short day hikes, long all-day hikes, and used it for general traveling. The pack provides great support and is very comfortable.

I can easily fit all of the gear I need for a day: rain layers, three liters of water, water filtration system, snacks, my Keens if I'm doing a hike near water, first aid kit, etc. Every time I've packed my pack, I feel like I could have fit more very comfortably.

The pockets are all well-placed and easy to use. The side mesh pockets hold things really still, and the front mesh pocket is great for snacks. The main compartment has a great additional zipper that lets you get to the stuff you've stowed at the bottom of your pack.

The frame system keeps my back a lot cooler than packs that sit right on my back, and the support system keeps the weight pretty evenly distributed.

My two negatives: The first is that the hip pockets don't fit an iPhone 6. I mostly keep chapstick and tissues in them. My old osprey pack had a digi-flip on the strap and I really miss it. The other con is that osprey reservoirs are great, but really make sure you're screwing the cap on the right way or water will leak every where.

Amazing Day Pack

Isabel, I am jealous of where ever you are! Beautiful! Thank you for writing about the Mira 34. Great review. This pack was designed before the 6 came out (like 3-4 years ago) so its no wonder it doesnt fit! Pack design doesnt change quite like technology... its a slower process all around. But know that they have heard this feedback. Also, the lid to the reservoir - definitely noted! Look for some cool updates moving forward.

Thanks again for reviewing the Mira 34!

Perfect Day Pack

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

I recently took this on a 14 mile hike. I needed to carry 5 liters of water, plus my hiking needs. So, it was important that this pack had plenty of support. It did and I was very comfortable.

Pros: The suspended, mesh back did keep me cooler than other packs that lie right against your back. The hip pockets were very useful. I had plenty of room for a rain jacket, lunch, snacks, sunscreen, and 5 liters of water. The water bottle pockets on the side work very well. The bottles don't move at all, even if you lean over. The water reservoir was very easy to use.

My con won't be a problem for everyone. I have a phone with a big Lifeproof case. I use my phone for photos, so needed to take it in and out of the hip pockets. It was a very tight squeeze. What I really need, is a better camera.

Hint: Put your fruit in the outside mesh pocket. It will keep it from getting knocked around and bruised.

Perfect Day Pack

I'm debating between the Mira and Sirrus...

I'm debating between the Mira and Sirrus packs as a gift for my wife. It's intended for day trips with the kids, whether to a theme park or the zoo. Has anyone compared them for similar use?

Best Answer

I was looking at both for leading trips with kids. Last year I had groups of 10 year old girls, and though they were multi-day canoe trips, I needed a daypack to keep with me in the boat for portages and easy access to the med-kit, layers, snacks, etc. I narrowed it down to this pack and here's why: when you're with kids, as you know, you need easy access to everything. For the larger Sirrus packs, the top loading just isn't practical for digging things out fast. I keep a med kit with me when I'm with the little ones, and I need to know I can get to it right away. The Mira also has more pockets. This allows for better organization for everything from maps to books and snacks for when the kids get tired and need a break. Extra layers are perfect for the stretch mesh front pocket. I try to keep a few extra rain jackets on me. Sometimes the parents of the kids I'm leading send their children out with ponchos thinking that that's acceptable for multi-day trips. For what you're doing, it sounds like you'll need organization. Though both are great packs, it'll be a huge time saver to go on day trips with the Mira. I'd pick the Sirrus for more ultralight backpacking type trips or for climbing where I can just throw a rack or two in a bag and go. Hope that helped!
