Great general purpose day pack
This is a great, well made day pack. Workmanship and materials are top notch. The fit is very comfortable (5'7", 145 lbs) - carries weight well, hugs the torso so it's very stable. The mesh back gives a little air space for the back. The must have feature for me is the separate compartment for the water bladder. I refuse to buy any pack where I have to empty out half my stuff just to refill my water. The quick disconnect makes refill simple and mess-free. I would prefer two compression straps on each side for when I carry hard, heavy tools and collapsible steel handles. This kind of load is heavy, which the pack handles just fine, but not very large volume, so it really needs to be compressed down at both the top and bottom so things don't rattle around. For normal day hiking, carrying a mixture of soft, bulky items and heavier items, one compression strap is perfectly adequate. The side mesh and back stuff pocket are strong and thick, which makes them not very stretchy. Depends on what you want to put in them. With the great hydration system in its own compartment, I never put water bottles in the side pockets anyway. The other must have is the load lifter straps. Not all packs of this size have them, so glad Gregory puts them on this model. I do wish there were a few more loops sewn in to carabiner things to the outside, such as a hardhat. Otherwise, there are plenty of pockets for smaller items. The yellow color is perfect - light and fun but still earthy and not garish for being in the wilderness. Definitely would recommend for many years of trail use.

Great pack, mineral yellow is not it.
The pack is great. The mineral yellow is not. I was so excited for a beautiful yellow pack, but it was more like a dirty yellow color.

Ehh not bad could Be better
Bought based on reviews and was very excited to get on sale during Black Friday. I’ve been using my bf osprey talon 22 so that’s all I have to compare it to. I like that it comes with the hydration pack already included bec I feel like you save money in that aspect. Accommodates 2 water bottles and smaller pockets for snacks and other things. Sunglasses holder is a plus. Side straps fit small items like chapstick or snacks. Was also looking for one that had the air flow in the back for hikes and one that carries my hiking sticks so that fits the bill What I do not like: the backboard is like a stiff washboard as mentioned in someone else’s review I don’t know why it bothers me but it’s way more prominent than the other backpack I used that has this. The bag itself falls over and won’t stay put unless you place against a wall or something. I’m not a fan of the strap that goes across the chest -prefer the clip style and don’t know how to explain what this is but it’s not the same as clipping and unclipping. I don’t feel like the bottle holder on the side is big or wide enough. Barely enough room to get my yeti water bottle to fit and you can’t reach back and do it like I’ve done with other backpacks- I have to really work it in there. Overall- it’s not terrible but not sure I’d purchase again. Also I take when I travel in airports and felt like even with the hydration pack not included it’s so slim to get anything to fit in the main part of the bag.

Comfortable fit
NIce size pack and comfortable fit. I did have some issues with the bladder leaking, but that was probably user error in not reconnecting everything. Biggest grip on this pack is that the hip belt pockets are just so small, with a little help from a friend I can get my phone stuffed in a pocket and zipped but it is not an easy task. I do love the bag color.

I absolutely love this pack!! The fit is perfect. I can feel the breeze on my back. The carry is super stable. The build is durable. And the hydration bladder it comes with is so easy to refill.

Great Day Pack!
Great reservoir for water storage, good amount of space for the 10 essentials and rain gear and I love the color. Fits great (I am 5''6 and 120 lbs).

I didn't see that it has a rain cover attached at the bottom. Is that really true at this price point?

What size pack is this? I am a 5'5" woman, 121 pounds and measure a hair or two more than a 19" torso. Would this fit?

If it doesn't have an adjustable torso, how does it fit anywhere between 14-18 inches?! (Just learning about hiking packs, nervous I'll end up with another that's too big, I'm quite small!)
