Rated 2 out of 5 by from Great Pack but... First off I think the design of this light-weight pack is almost perfect for my needs: large opening for the main compartment; two roomy water bottle holders; small, (outside) compartment w/good ventilation; and the top cover w/a compartment, nice. The thin shoulder straps great for ventilation, and comfortable. This pack feels great on my back. But... The stitching around the top cover is coming undone, and the mesh for the water bottle holders--not durable: keep it away for abrasive surfaces (e.g. rocks) it will not hold up. I've used this pack only once on the trail--so yes, very disappointed w/its durability.

Rated 5 out of 5 by from Perfect day pack to add to a backpack I have an REI backpack (Traverse 70) that came with a detachable hood. The hood converts to a woefully inadequate fanny pack or shoulder bag - nothing you could really use to take short hikes from a back country camp. So I bought this day pack, added some camlock buckles to it so that I could clip on my REI backpack in lieu of the hood, and now I have a backpack with piggyback day pack that weighs only 6 oz more than the original hood that came with the backpack. This pack is great - has a pocket for a water bottle, and is big enough to carry the 10 essentials and a coat. This lets me take short scrambles from an overnight camp - just what I wanted, without adding a lot of weight.

Rated 4 out of 5 by from Light and roomy, but fabric will give out I use this pack for day hikes and also errands around town (groceries, etc.). I've generally been pleased, but after about a year or use the fabric has torn in the front seam above the front zippered pocket. I use my gear extensively, probably overstuff it, and don't treat it gingerly, so I'm not completely surprised, but I didn't expect to be shopping for another pack this soon. Overall, for the uses I purchased this pack for, I think it is a reasonable compromise between durability and low weight, and I would recommend it, so long as you would make the same tradeoffs I have.

Rated 5 out of 5 by from Impressive little day pack I got this backpack to hold a plethora of items for a day hike, bike ride across town, and visits to the climbing gym or quick trip to the crag when I only need to bring the bare minimum (harness, shoes, chalk). I've been impressed with how much stuff it can carry, and the outside mesh pockets are perfect for holding a can of bear spray, or my smelly climbing shoes without stinking up the inside of the pack. The straps are fine, as long as you aren't looking to carry super heavy items that will weigh the bag down. The fabric seems pretty durable, but I probably wouldn't be throwing it around the campsite or dragging it along the rocky ground. All in all, great little day pack for the bare essentials.

Rated 4 out of 5 by from Perfect Ultralight Option I bought this pack for its weight and stowability - both of which are perfect. The best use is for people who want a minimalist, super-lightweight day pack that fits very well into a backpack or carry-on luggage.   I've worn it several times and the fit is very good and comfortable. Even with the minimalist shoulder & hip straps - it never rubs or feels too little.  The volume is perfect for the 10 essentials. My only issue is that with no ventilation between the pack and my back - there is considerable moisture build-up (my back was soaked). However, not using the chest or hip straps mitigated that issue somewhat. Overall - I'm very satisfied with the quality and functionality of this ultralight daypack.

Rated 2 out of 5 by from Diappointment I realy like the lite weightness of this pack. I know it is not a heavy weight carrier, and I used it twice with 6 to 10 pounds in the pack. But the Shoulder straps are VERY bad. They use a 1/2 in wide and the padding in the straps, which there is none, does not help distribute the weight. So even though there is not much weight the 1/2 inch nylon straps is what you carrying all the weight on. I wanted to like ths pack but in the end I returned it, due to the porrly designed shoulder straps.

Rated 5 out of 5 by from Impressive Pack This is a very impressive pack. I bought it when it was on the outlet so I can't say for the price. However I put this pack to the test when I took it canyoneering for the first time. Did MicroDeath Canyon in Escalante Grand Stair Case NM (on the narrow side for canyons). Swimming though the water, repelling, and squirming through the slots this little light pack held my gear and worked wonderfully.

Rated 3 out of 5 by from A very good pack just short of great. I needed a light-weight, compressible pack that was big enough to carry clothes, sleeping supplies, sundries etc for a trip through Cuba. This pack excelled except when carrying small but heavy-ish loads. Since it lacks any internal structure and only has compression straps located at the middle of the pack, it is difficult to cinch tightly when carrying just water bottles and books. So to get the best usage from this product I used dry sacks to help control the distribution of weight and increase organization. Some suggestions for next years model: 1. Use the same mesh material from the straps on the back to help increase airflow. 2. Corrugate the pad and reduce the size of the envelope where the pad is housed to give more shape while keeping the weight down. 3. Add an extra, lower compression strap.

what size bladder fits in this? 2 liter? 3 liter?

Asked by: maryo
While a 3 liter hydration bladder can fit inside the Marmot Kompressor Plus 20 Pack, a 2 liter will be a better fit and save room and weight in the pack.
