Here's what others have to say...

No problems, exactly what you want

  • Familiarity: I've used it once or twice and have initial impressions

This is a great running vest. I love the pockets and the stiff meshy type of shoulder material. I had trouble deciding between this one and the Krupicka... I was worried the Jurek was going to be quite a bit more bulky, but it really isn't.

Great vest long-distance trail training

  • Familiarity: I've put it through the wringer

This has been a perfect hydro vest for ultra training. I was originally a bit hesitant of moving to a pack with bottles on the front (pervious packs where back bladders), but I've found this to actually be much more comfortable, and even as the bottles empty over the course of your run, the vest stays stable and comfortable. After a few miles, you barely notice it's on.

The pockets are really useful, and it's nice to have the stash pickets for gels/bars directly tucked into the bottle pockets. Also, the main side pockets are perfect: by having them back around the side, they don't put any pressure on your body, even when full with bars/phone/random stuff.

And as someone who has been using this vest in humid Brazil for the last year, I can't tell you how amazing the materials and water-proof aspects are. The small pocket on the front left is perfect for keeping some money/bills, and will stay perfectly dry. And the pack as a whole breathes incredible well, dries quickly, and the main compartment even keeps everything more or less dry regardless. Plus, my being places fairly high on your back, it minimizes the amount of sweat that other running packs that sit lower might produce.

A note on size (which I went back and forth on a lot before making my purchase. I am 6'2", 170, so that awkward place between medium and large. I ultimately went with a large, just to have some flexibility for when I need to pack the vest with jacket, food, supplies, etc. That being said, I probably could have sized down to a medium and it would still be fine. As is, I tighten the side straps (found inside the pockets) and the pack is plenty comfortable and stable. I haven't yet used the vest with a jacket (Brazil, remember?) but I imagine that having a large will also better accommodate layering when needed.

One suggestion I would make is to make the front chest pockets a bit larger, to be able to fit a phone, so that it is immediately accessible for taking photos, or changing songs if you're listening to music. But on the whole, this is a fantastic vest, and highly recommend for anyone looking for a functional, sturdy, and (admittedly) stylish vest for trail training.

So, I'm a bit concerned about how difficult it is to drink from the water bottles. You've really got to chomp down on the nozzle to get any liquid out. Am I missing something here? If I'm running an Ultra, I really don't want to spend a lot of effort just trying to get the water out of the bottles.

Hi there. The UD bottles are designed to focus on that red Kicker Valve. To make it leak proof AND high flow, squeeze the bottle while tilting it up slightly. You should get a fire-hose shot of water! It takes a little getting used to (compared to other bite-and-suck bottles) but delivers a lot of water quickly. We've also seen a lot of runners replace the bottles with our Body Bottle and Body Bottle Plus for a more traditional valve. Good luck, and thanks for the feedback!

Solid vest

  • Familiarity: I've put it through the wringer

I use this vest extensively for ultrarunning and even some ultralight peakbagging. The fit runs a bit large if you ask me but I am a small and went with the medium based upon other reviews. Easily holds a ton of gear and the many front pockets, slots make your often needed essentials readily available.

Glad UD can be part of your adventures, Hoyawolf!

New features for the SJ 2.0...

How would this vest do on carrying non Collapsable trekking poles??

Responded on

Hi Josh. The SJ Vest has 2 trekking pole loops plus a bigger ice axe loop and strong bungee cord on the back. You could definitely get regular poles on there, but they may rock a little, depending on the real length of the pole.

Are you planning to hike with this pack? Maybe check out our Fastpack series also, which would easily carry regular trekking poles more securely and still have the light weight and great fit of our race vests.

Saves the day mile after mile

  • Familiarity: I've put it through the wringer

I purchased the SJ vest last year around this time, and it is still going strong. I've never had a chafing issue with it, even at the 100 mile distance. It is very easy to carry all your long-run needs in this, especially with the bungees on the outside. The bottles are easy to use and are leak-free. Pockets are easily accessible for phones, gels, water filters... whatever you feel like packing. Durability is no issue, and it is practically weightless. I would strongly recommend this product, and feel it has been a huge benefit to both my training and racing.

It has many pockets to take along what's needed. Did 14 miles with ups & downs and its comfortable to wear.

Still loving it! I've been wearing it for runs over 4 miles for the past 6 months and it is still incredible. Way to go UD! Way to go...

This was taken at the finish of a 50 mile ultramarathon. I wore this the entire time. Great for gels and water bottles. Kept my shirt safe and sound. Only problem was some light chaffing around the bottom sternum strap. But otherwise Flawless!

When UD says they've thought of everything...they have.
This vest is remarkable. The materials are tough! The fit is fantastic. The straps are easy to adjust on the run, the pockets are easily accessible (lets face it, this is the reason for a race vest).
Some highlights: The materials stretch to fit any body type. The Cuben Fiber is so thin, but super tough (Looks for it in shells soon). The stretch material in the back of the pack shrinks along with a bladder, should you care to carry one, and doesn't let a single thing jingle or jangle. The pockets under the arms are wonderfully placed, easy to grab a phone on the run. The Gel pack pockets are in great positions.
I can't say enough about this vest. It comes with 2 ultra hightech nipple bottles that won't spill a drop. I must say, when I opened it, I had some serious reservations due to the tiny size, but man is this thing perfect. Totally worth the investment.

Do yourself a favor and buy one.

I was considering going with the AK but the SJ seems the way to go with the extra storage pockets.
