    Great pack for all runs where you don´t need to bring so much mandatory equipment with you, great for training too. I did a lot of trail running with this pack, a lot of training and some trail half marathons and a trail marathon. It fits perfectly – I love the Max02 Sternum – it´s easy to open and close with one hand and easy to adjust while running. This pack has enough space for a 1 l bladder and the bladder sits perfectly – no bouncing, it´s easy to place the bladder, refuel it and put back…The elastic cord on the back can also accommodate a jacket or even a pair of sandals. The front pockets offers a lot of space, a 500 ml soft bottle fits great in, or a lot of other stuff! On longer runs or in hot weather, I can additionaly to my bladder also carry a soft flask in front and I still have one big front pocket for my (large) cell phone, some Kleenex, energy and other small stuff. The waterproof pocket is great not only for salt but also for plasters/adhesive bandage. Great and simpel pack, easy to adjust so it fits! And the lime colour is different from most other packs, so it´s easy to be recognized and seen.

    I’ve been using the Spry 2.0 for about a year now and love it. However, the updates to the 2.5 are just the bomb!!!! The extra MaxO2 sternum strap makes a huge difference – especially to someone who is small framed. The storage is amazing and I really love the trash pockets. The front pockets are large enough to carry my phone and a charger for my watch, as well as extra snacks. This is a really great pack for races or long runs!!

    This pack is amazing! I’m a middle-size middle-aged woman and I struggled finding a pack that was built for women. This one is it! I usually get pinched under the arms or the bladder jiggles everywhere. Not with this great pack! I love that it has so much storage in the front so I can easily gain access to my gels, chews, flashlight, phone, etc. I used a 2L bladder and it fit well. There are lots of cool little pockets too for smaller things. When I finished my run, I just put this (without the bladder) in the wash and it came out great! This pack has made long runs enjoyable again!

    I was looking for a minimal, light-weight vest with a few pockets to carry my phone and key. The Spry worked out great. My phone is a Galaxy 5, fairly large, and fits with room to spare. Also, I have a 46″ chest and the Spry fits.

    I bought this pack during a buildup to Western States 100, for something sleeker to race in. It was so great i bought a second. IT fit my small frame 5’3” 105lbs perfectly, it sits very comfortably-not Too high -not too low on my back. IT has plenty of pockets and places for nutrition and hydration. I especially like the small side stash pockets for trash. The only downside is that the material the front pockets are made of were abrasive to my technical shirt fabric when the pockets were Half full.

    I have been using this vest for more than a year now, and there are many things I love about it. The MaxO2 sternum creates a perfect fit that doesn’t come loose during your run, a point which always made me crazy with other brands having to constantly re-tighten the straps during the run. The S-curve shoulder straps fit the contours of the body nicely without being abrasive around the neck or ribcage. It’s light, breathable material stays relatively cool and comfortable, and for the size of the vest, it has ample storage. I’ve used this vest in daily training, marathons, mountain races, and Spartan races, and it has performed well in all conditions. The only downside I can think of is that the material faded rather quickly (I have the yellow version) into a drab greyish-yellow. As I train mostly at night, this is not a product of sun-bleaching. Overall, a stellar product, and I would buy it again.
