CamelBak Cloud Walker
Really great daypack — durable, spacious, awesome hydration system.
Reasons to Buy
- Durable
- Awesome hydration system
Reasons to Avoid
- Wish the small front compartment had top access instead of side access
The Cloudwalker is a great daypack. It features a row of gearloops on the front for clip-on storage or for holding a small-handled implement. There is a smaller front storage compartment with an organizer pouch inside with small zippered storage space (think wallet) and room for smaller items such as maps, snacks, camera, gps, phone, etc. The front compartment is accessed via a vertical zipper running along one side of the front. I prefer a horizontal zipper for top access to lessen the risk of something falling out and for better visual access, bit it's a minor gripe. There is a mesh pocket on one side of the bag for quick-access storage. The main compartment is roomy enough for a day's worth of stuff for most outdoor pursuits.

CamelBak M.U.L.E.
Good durable pack for single-day use. I've found this pack carries enough water and materials for up to one full day of hiking (no overnights) and can also be used for mountain biking without being too cumbersome. Offers enough space to pack light rain gear, emergency supplies, light, tools, tubes, camera etc.
Reasons to Buy
- Durable material seems impervious to thorns/prickers, zippers also durable.
- Pouch/pocket placement and size seems well thought out. Special pouch for cell phone.
- Rides well when not "maxed-out."
Reasons to Avoid
- When "maxed-out," this bag puts a strain on your back and shoulders.
- Waist buckle may not fit larger people or over heavy winter clothing.
After about 18mos with this pack everything is holding up well. The material seems to be impervious to thorns/prickers showing no obvious tears. The water bladder is well protected and has not leaked at all. The zippers have been durable and show no signs of giving in anytime soon. Like most Camelbak products, they might not always be cutting edge, but they work and deliver. Now that we've established it is durable, its uses; I use this pack for day hiking and mountain biking. Occasionally I will use it for my motorcycle as well, when I don't feel like putting my travel luggage on the bike itself for a short ride.

CamelBak Rim Runner
Great day pack, just a few little things make it uncomfortable.
Reasons to Buy
- Capacity
- Compression
- Pockets
- Design (panel load)
- Frame sheet
Reasons to Avoid
- Hip Belt/strap
- Frame sheet support
- No extra adjustments
First off, my pack is NOT the one pictured. But it is a Rim Runner according to the tag. This is the model I have. I believe it's a 2007 model. I have used and abused this pack and it has stood the test of hard time. I love the compression straps, the back padding, the shock cord on the front of the pack and the little loops right above. This pack has went just about everywhere with me and has taken some abuse. It has bounced off rocks and taken loads it was never meant to haul to secret campsites. Now days it goes with me on at least 2 hikes a week that are 3-8 miles in length. This is however a review so its time for some +/- When I went for a Camelbak I was going for a small daypack and I got more than I thought.

Salomon Adv Skin 12 Set
Amazing fit, so many features, and it is variable allowing a lot of flexibility. You'll forget you're wearing it.
Reasons to Buy
- Good fit
- A lot of features
- Comfortable to run in
Reasons to Avoid
- Not durable
- Pole straps don't work very well
I definitely don't run much further than 30km at a time, so I was hesitant to pick up a pack designed more for long ultras. But with the variable conditions I run through this has ended up being a fantastic running vest/pack. Despite looking a little silly, I actually take it hiking too just because it is so comfortable. And when I need it just for holding a can of bear spray comfortably it works well as it packs down pretty small. The 3D fit system is amazing. The mesh is highly breathable thanks to having a bit of soft structure to encourage airflow.

Osprey Duro 6
A well thought out running vest for all-day mountain runs, bounce-free and with sufficient capacity for basic safety gear, an extra layer or two, plenty of water, and enough calories to get to the end of the trail. The trekking pole attachment system needs improvement.
Reasons to Buy
- Snug, bounce-free fit
- Three zippered compartments for critical gear
- Lots of stretchy pockets for bars, gels, and snacks
- Twin 500 ml soft flasks plus optional reservoir
Reasons to Avoid
- Trekking pole attachment is a bit awkward
- Soft flasks tend to fall into pockets
A piece of the Trollheimen Mountains in mid-Norway 15 years ago, I switched from mountain biking to trail running as my main summer fitness activity. I had various reasons for that, but the main one was that my daughter Molly challenged me to try to do the 60km (36 mile), 2500+ m (8200 ft) Trollheimen Triangle in a single day. The Triangle connects the three main full-service huts in the Trollheimen Mountains, a few hours’ drive from my home in Trondheim, Norway. The trails are mostly rocky, rooty, boggy, and either up or down, only rarely flat and smooth.

Ultimate Direction Fastpack 15
A great pack for long days in the mountains; even a bare bones overnighter.
Reasons to Buy
- Carries very nicely and stable
- Pockets are laid out nicely
- Low profile for off-trail travel
- Quality materials (Robic fabric for the main body) and stitching
- Roomy external stretch pockets
Reasons to Avoid
- Don't like the clasps used for the sternum strap
I've now had about dozen mountain runs in the 18-25 mile range with this pack and can state unequivocally, it's a keeper. This is really a nice sized pack for an all day adventure; with its stretch pockets it's very close to 20 liters. I typically have mine loaded with 6-8 lbs (about 1/2 that in water). Pack carries very nicely—no bounce or sway and it's very comfortable. The pockets are laid out nicely and easy to access. I was happy to see that my favorite water bottle (a repurposed Vitamin Water bottle) fits perfectly in bottle pouch.

Osprey Raven 10
Excellent for hiking and mountain biking—sits close to your body and high on your back which makes mounting and dismounting on a bike easy. Ample storage space and compartments for riding/ hiking essentials without being bulky. Smart, functional design features like helmet clip and roll out tool storage make it a worthy piece of equipment.
Reasons to Buy
- Ample storage space/ convenient compartments
- Excellent women-specific fit with ventilated back panel
- Sits high and close to the body/ great adjustability for different uses (cycling/ hiking)
- You can't beat a lifetime guarantee
Reasons to Avoid
- As with any hydration pack, the bladders are hard to dry. Do yourself a favor and get the drying rack.
Excellent fit and adjustability, ample storage space and compartments. I use it mainly for mountain biking and commuting to work. When mountain biking it stores all the tools I need to replace a tube, and all of the snacks and hydration I need for a good 3-5 hour ride. For commuting to work I remove the bladder and am able to carry a full uniform (shirt/pants/undergarments/shoes) and another kit for the ride home (yeah, I sweat a lot and won't use the same kit twice). Versatile, comfortable, and convenient. It doesn't get much better than that. And thanks to the lifetime guarantee I don't feel uncomfortable putting those zippers to the test.

Osprey Raptor 14
Great pack for short day rides and hikes. Carries the basics. Super comfortable.
Reasons to Buy
- Great design
- Functional, well thought features
- Fits tight for riding and trail running.
- Side mesh pockets for waterbottles etc.
Reasons to Avoid
- Channels on foam back are horizontal, rather than vertical, which I think would be better for upward air flow.
- Also, hip pockets only have elastic, not zippered closures.
I am a woman, 5'8". I have the m/l and the fit is great for me. It's a perfect all around pack for short hikes and biking treks. Holds all the essentials. Lunch, snacks, first aid. A few extra pieces of clothing.Bike tubes whatever. Three liters of water and stretch pockets on the side for added fluids if needed. We just did a overnight trek to Half Dome and a friend used this pack while I used the Manta 25. She was able to fit almost as much gear as I had in my 25! The torso size was slightly big for her,so she will be getting it in the small/medium.

Gregory Pace 3
The PERFECT pack for trail running adventures. You will forget you are wearing it until you need it.
Reasons to Buy
- Woman-specific fit
- ZERO bounce
- Flask holder
Reasons to Avoid
- Back pockets not really accessible while running
- Lack of large item storage up front (fixed with add on pouches)
This pack rides BEAUTIFULLY!!! ZERO bounce (when set up correctly by removing all air from bladder prior to putting inside pack). It can hold up to 2L of water, but I rarely need that much so I am typically filling it with 1 to 1.5L, but I like having the option to fill if I need more. I have worn it on ALL of my multi-hour trail runs (including marathons and 50K's) and it has NEVER let me down. I LOVE the gel flask pocket as it fits my hammer flask perfectly. My only complaint is that the back pockets are not really accessible while running unless you are a contortionist.
