Question: is this bag has the metal bar at the back?
Document: I only wish the straps were a touch wider, so the pressure wasn't focused on such a small area of your shoulders, but tightening the bag closer to your back helps with this. Not enough to knock off one star.
I absolutely could not be more happy with this pack. It is soo light. It holds everything I need for a day trip or for a very extended camping trip. I can just barely feel it on my back with my 70 oz Camelbak in it, tent, and sleeping bag. Frame disperses the weight and makes it so easy. I love it!
The tool loops and lash points are well placed on this bag.Since I needed a larger bag, I sent this one back and ordered the 4000 model. I'm currently waiting for it to arrive (1-2 month expected delivery, even though the 2-day Free Shipping option was available for Prime members). Hopefully this will be the PERFECT pack for me, and hopefully it will get here before my backpacking season ends.Overall, the Hiker3700 Ultralight is a very good pack, and is VERY affordable.
This is an excellent pack for the money. It holds enough gear for the hikes we take and wears well on my back. Highly recommended.
My husband loves this ack. He has used it a few times. My hubby is 6 ft and his torso is long. He had a different one but it hurt his back. Tons of room and pockets
Daughter used for traveling across Italy and staying in hostels. functional - of course you have to recognize the weight on your back. just what she wanted so we were pleased with super quick delivery before her trip
For the back packing vacation we are planning is just what we need, i can definitely use a couple of extra small compartments but not a big deal. I love the lightness but I'm sure I'll need to be careful on how/where to use it
I'll keep it short, the pack rocks only weights 3.5lbs is tear resistant and has tons of adjustments. The  2 internal stays are easy to use and adjust to the profile of your back... Can't beat the price!! !
To put this review in context, I was not able to &#34;Field Test&#34; it, and sent it back after a &#34;Living Room Test&#34;. I loaded the pack and wore it around the living room for a few evenings.I own a larger (85 Liter), MUCH more expensive, pack - but wanted something more affordable for shorter trips.
When i recieved the pack i was excited because it appeared to have everything i wanted. I prepared my pack and went to mammoth cave for a 15 mile overnight hike. The pack held everything i needed for the trip and had plenty of room left over. After about 2 hours into my trip i took the pack off to rest for a few minutes. When i put the pack back on it ripped. I completed the trip although my pack didnt sit right thinking i would fix the pack when i returned home.
Answer: yes
