Amazing Day Pack

  • Gender:Female
  • 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

  • Gender:Female
  • 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!
