AT GA-ME, 2010 from United States, VA Public Profile

Already had to use it to pull rose thorns out of my foot. Sharp and pointy, the tweezers effectively dig into skin. Magnifier is great as a viewing tool and fire starter. Great addition to your pack's utility kit. Be careful not to scratch the lens folding the tool.

I purchased the 2L model to provide 11 miles of water carry for mountain trail running on the AT during hot summer months.

I haven't use this product in the field yet (3 months hence), but I have run it through some preliminary, out of the box tests.

I did fill it up and insert it into my 2015 MountainSmith Day TLS lumbar pack (also purchased from Campsaver.com). I placed it vertically into the stretchy fabric compartment against the back, and the pack easily zips closed. The 2 hoses can exit either end of the pack due to the double zippers on the pack, so no pack exit hole modification was required. I also tried placing the bladder horizontally. The horizontal fit is snug, which is desirable to minimize movement of the bladder while running. Storage of other gear seems more convenient this way, also.

The stated dimensions of the bag shrink when filled with water, allowing it to fit horizontally and vertically within the 12"Vx10"H pack dimensions .

I don't expect any problems with water delivery due to orientation since the water is pressurized, not gravity fed, but having the water exit port of the bag in the lowest vertical position is standard procedure otherwise.

Ran 25 miles of the AT in central VA in mid July carrying up to 12 lbs in this pack. I added the strapettes and hooked my 11L Ribz pack up the front and to the bottom and top of the TLS. The daypack was snug and comfortable the whole way. Despite my water treatment equipment hanging in a mini sack off the rear, secured by the bungee cord, and carrying a max of about 1.75 quarts of water in pack and bottle compartment, it remained snug to the body, not bouncy. Sweat about 5.5 quarts of water that day, but have no recollection of feeling overheated or clammy around the waist with the cushy back and wide, hip grabbing belt (wore nylon pants, a wicking shirt and wicking underwear underneath). Most shoulder packs put most if not all of the weight on the shoulders. The TLS allows you to transfer most of the weight off the shoulders to the hips where it's more comfortable. The TLS is in my opinion the perfect answer for trail runners looking for a snug, comfortable trail running/camping experience.

Used these for 27 miles of trail running on the AT with the Day TLS lumbar pack. Padding is great, quality construction, padding fabric seems breathable, easy to put on pack, but would like to see these become more comfortable with ventilated shoulder pads and a little stretch like the shoulder straps of the Osprey Talon 22. The shoulder strap I received with the Day TLS seems to be moving somewhat in that direction. MountainSmith, are you listening?

Needed for trail running with front and lumbar packs. Got two half liter bottles, one capped, the other with hyperflow cap. The hyperflow cap had a minor leak around the twist on portion, adjusting didn't seem to remedy the situation, thus nixed one star. Placed full bottles in Ribz front pack with hyperflow cap extended outside the zipper of one pack to prevent unintended discharge. When empty, the bottles rolled up and required little volume in pack. Very light weight yet durable. Sloshing can be annoying when running, and rigid bottles slosh as fluid is progressively evacuated. Compressibility of these soft bottles eliminates sloshing as walls collapse with evacuation.

I just bought this pack and received it today. I will definitely write a post-use review later, but I couldn't resist saying something now.

This is a quality built pack. The belt is snug yet stretchy, and it is very wide and secure. The pack grabs your hips and pulls into your spine. Loaded up and cinched, it seems to become a part of you, promising not to annoyingly jump around, something I look for as a trail runner. Putting it on with a load is very encouraging. The zippers and construction are top notch. It feels very durable. No question it can take some abuse.

I selected this pack for trail running with a Ribz front pack, giving me 25 L of carry volume and a body centered load for increased stability. I looked at combining small volume backpacks with the Ribz front pack, but I wanted weight transferred down to my hips. The lack of decent belt systems on such backpacks (that do more than stabilize the swing of the load) and no rigidity in the back panel meant most of the weight would be carried on my shoulders, making me very uncomfortable at an initial max combined carry weight of 19 lbs. The Day TLS was the perfect solution. I can't wait to actually hit the trail with it.

The center compartment will hold about 2 days of compactly packed dehydrated food (in my case 2.3 lbs x 2) and there is a front pocket that can hold my Golite Poncho and a mid-weight poly-fleece shirt. I'll put a wide mouth mixing bottle for protein shakes and veggie drinks in the bottle carrier on

I hiked the AT in 2010. In retrospect, the MSR Hubba is the tent I would go with if I had it to do all over again. I previously used an 8oz poncho tent with 6oz mosquito net during hot weather and a hammock tent during the cooler weather. I learned the hard way you want and need vertical space to maneuver in to better prepare for de-camping during rain, and if you want the much lighter advantage o
