This jacket is super comfortable. It has just enough space to do a little layering underneath. I like to layer this underneath:

I use these for hiking. They are very comfortable. I got the medium and they fit me perfect except that the waist is just a touch large (I have a 31" waist and a 34" inseam).

I took this pack on a week long trail running adventure in Guatemala and LOVED it. It was big enough to take water for almost a whole day every day. I only had to refill on particularly long days when we were out over 8 hours or so. I generally carried an electrolyte bottled drink in the bag to supplement the water.

I was able to carry the full bladder, the extra bottle of electrolyte, food for the day and an extra layer and still didn't have to open the expandable compartment (my extra layer was VERY thin though).

When the bladder is completely full, you will find that it moves around a bit while you run. But, I was still able to run with it.

I read a review that said the straps would slip. Even with it fully loaded, that did no happen to me.

The pack is very comfortable. It did not rub me weird in any places.

Love this pack. Recommend highly.

I was on this adventure if you want more details: http://www.mayanrunningadventure.com/

This pack has just what you need. It sits high on your back and is very comfortable. It has a hook for the bladder so it doesn't sag. Some people complained about that, but they must have changed the design. If you have a very large chest, it might be a little snug, but you'll probably still be okay.

She hasn't used it practically because it's too big for her and it's warm here now. But for some reason she still just loves it. Probably because it's pink. It's a cute coat.

Bought this for my wife. Very cute and fits her well. She's thin with broad shoulders and not very tall (short torso too). She says it's comfortable as well.

We've got a ton of these. They're just convenient. The only thing I don't like is that the bit valve gets dirty over time and is nearly impossible to clean out well. I bleached one of mine for a while and I'm sure that made it sanitary, but I still couldn't quite get all of the gunk out. It's nice that it has a big opening to put ice in, easy for my kids to drink from, etc. I only use this at home and work. I wouldn't use it on the trail. When I drive up to work (much higher altitude than my home) or when it goes from cold to hot, water tends to leak out of the valve so I have to keep an eye on that.

I haven't had to save anyone's life with this yet, but the quality looks good, it's easy to use, it packs up pretty small and it is fairly light. I also thought the price was right. Good product.

These skins are effective and I trust them. Sometimes it would be nice to have some Mohair skins or a hybrid because these do pack a bit large. But they also last forever and are reasonably priced. It's a good tradeoff.

I've been running barefoot for a long time (2 years?) Probably logged 500+ miles pure barefoot and another 500-1000 in shoes such as the Vibram Five Fingers and these Merrell Trail Gloves. Barefoot is great, but I really need some protection in the Rockie's. There's lots of rocks around here. ;) The Vibrams provide the closest thing to real barefoot, so I love them for that. But I've also injured my toes in them a few times. The Merrells protect your toes much better. The Vibrams are also harder to fit since they are toed. These have just a slightly thicker sole than the Vibrams. I feel like they give a lot of the barefooting benefit, but when I'm 10 miles out in the middle of nowhere, I don't have to worry about getting injured and not making it home. :)

I normally wear around a 10.5 and that's what I got in these, so they're reasonably true to size. My friends told me they had to size down a bit. Definitely don't size up. :)

I've been running barefoot for years. I keep trying to get my wife to try it but she thinks I'm crazy. Finally I got some of these merrells and suddenly she was interested. Why? Because they're cute and you don't look like a barefoot weirdo. Also, the shoe gives you a lot of the barefoot benefits, but still protects your foot pretty well from sharp rocks and stuff. So they are a pretty gentle intro to barefoot running. Since I got these, my wife wanted the, then my mother in law, them my brother in law...everyone wants them. These are good shoes.

By the way, since there's no "padding" to wear out, these things should last for a VERY long time.

Fit my 9 month old perfectly. She kept it on most of the time which is pretty good since she always rips bows and stuff like that off of her head. So it must be reasonably comfortable. And my wife and I thought it was very cute on her. Good buy.

Long, slim fit, which my wife loves. Comfortable and cute. Great shirt.

These are always the best. Super comfortable. Last forever. Love them (well my wife does, but I love the men's version too).

Bought this for my brother-in-law who is an avid runner and sweats a lot. He's going to start a running expedition on Guatemala (http://mayanrunningadventure.com) so he's running serious mileage. He's a bit picky about his running shirts and he RAVES about this shirt. Apparently its the best thing since sliced bread. I'll be trying one for myself soon.

Bought these for my Sister-in-law. She's 6 feet tall and says they're comfortable and fit great. She liked that they weren't too short.

Bought my wife a pair of these. She loved them and my sister saw them on her and wanted them too so I bought her a pair. I own the men's version. They're very comfortable.

My wife loves these. Bought her a pair and she said they're very comfortable and look great. Ended up buying a couple more as gifts for others. Great sandal.

These are great form fitting socks. The are comfortable and they are a great deal. They are a bit slick in your shoe, but that's what this type of sock does. I wouldn't wear them in hiking boots. I'd use wool socks for that. These are great for my tight fitting bike shoes and I wear them for running too.

I chose these because they perform pretty well and stay on my head well while running, biking and playing tennis, yet they still have a nice look to them for just wearing around town.

I love this jacket. The fabric repels water well, yet is very soft and comfortable. I have had several friends and family try it on and they are all very surprised at how soft and comfortable it is.

I have worn this jacket only in mildly-cold weather so far. It does a good job of keeping the wind out and keeps me warm, yet in the middle of the day when it got warmer, I wasn't roasting in the jacket, so it feels like it does a pretty good job of breathing.

I bought this as a present for my niece. It works great because the mouthpiece stays clean and doesn't drip if she drops it.

I can't give this five stars because it is a pain to pack this around and it does dent easily. So, I probably wouldn't pack this around too much. I like it just for a jug to take to work. I have juice, milk, and whatever else in this and the smell/taste are gone with a simple rinse. That's why I think it is so great. It is also nice that it is BPA free, but there are a lot of other good BPA free options out there if you care.

I hate getting dehydrated on longer runs and I hate carrying a water bottle. I tried a traditional hydration pack that goes over your shoulders and couldn't stand the bouncing. This is perfect. It doesn't bounce and it carries just the right amount of water to last me about 1-2 hours on the trail. If I try to wear this on my hips, then it does bounce a bit as it tries to migrate to the most slender part of my torso. I find it best to just place it a bit higher and then it stays put really well.

I like the shirt a lot, but just beware that it is a little short. If you have a long torso, you'll have to get a larger size and then it will probably be too wide. No problem with the shirt, just beware if you have a long torso and you're slender.

I wear this for running. It wicks well and keeps me cool. I haven't had any problems with it.

These are kind of cool because you get a slightly thicker/padded sock that is still super lightweight. I found them to be quite comfortable.

I like having lightweight shorts for running, but I am not "daring" enough to wear those tiny runner's shorts with the slits up the sides. These are really comfortable and light. I love running in them.
