Camelbak M.U.L.E 3L MIL Spec Crux Hydration Pack - Multicam

I'm a biologist that does a good amount of field work in the southern US. I've been using a large Tactical Tailor bag from my time in Iraq to carry around the usual supplies- reference books, reflective vest, pens, notepad, rulers, water bottles, rain jacket, aid kit, etc. As bomb-proof as that bag is, it's just way too big to be carrying around in the brush. I wanted a hydration carrier that is small, organized, and can take a beating.I found the M.U.L.E. a few weeks ago, and it seems to have solved all my problems. I put the bladder in my cooler on the way to a job site and it stays cooler for way longer than I ever use it. Additionally, now I'm not throwing away plastic bottles every time I use them.

The M.U.L.E. holds everything that the previous bag does and it's 1/3 the size.My only real complaint is that the straps are a tad uncomfortable, but I'm willing to put up with it considering how well it does everything else. Easily the best buy I've made in a long time. I'm considering buying my wife one for whenever we go hiking and camping.

Given as a gift. Fits well due to many adjustments. Easy clean. Water stayed cold for about 18hrs. Outside holds items with difficulty, easy to clip and unclip dog bowls.

I love this pack. I bought it for its reputable durability, and it held up well during my recent travels. For a low-profile design, It holds a lot of space, even with a full 3L reservoir, and the reservoir will typically last a whole day without refilling. You can't go wrong with this one if you're looking for a durable reservoir pack with decent storage space. It has all the essential pockets and a good tube management system for underarm/over-shoulder ports, and water stays generally cold in excessive heat, but water in the tube can get warm - I tested this in Mexico's tropical weather during my adventures. My only complaint about this pack would be the shoulder straps. If you're wearing a layer with this pack (sweater etc.) at full capacity it's completely fine, ... MoreI love this pack.

If you're wearing a layer with this pack (sweater etc.) at full capacity it's completely fine, but the shoulder straps over a t-shirt/tank top will rub against the skin. But again, only if the pack is fully loaded. Overall, this is a great pack and I highly recommend it!!
