The Saguaro Vest
KEY FEATURES
DESCRIPTION
Built for long days in the saddle. For the fasted times out there or for the long way back home.
With two zippered chest pockets perfectly sized for snacks or a oversized phone and two drop pockets for fast-grab items (Chapstick? Half a bar? The Saguaro keeps your essentials tight to your body without the dreaded bounce.
Around back, there’s a dedicated sleeve for a 2L Hydrapak bladder — and a separate main cargo zone with side access, so your zipper isn’t caked in rear-tire mud halfway through the day. It is easy to sling the vest around your shoulder to grab stuff quick without taking it fully off. Internal organizer pockets make gear sorting easy, and a key clip keeps your truck key out of the canyon.
The 2 daisy chains down the outside of the pack make for a great haul all option. Jacket, knee pads, chin bar, really whatever you can fit.
Breathable mesh shoulder straps and back panel help you keep your cool.
FIT
The Saguaro Vest is designed to fit most riders with an adjustable, low-profile harness system that stays close to the body without restricting movement. The Sternum straps are adjustable up and down for a comfy non-revealing fit. If you're somewhere in the S–XXL range, you’re likely good to go.
That said, riders on the smaller end of the spectrum (particularly petite or narrow-framed folks) might find it tricky to get a snug-enough fit. And if you typically wear larger than a men’s XXL, The Saguaro may not have quite enough room to fit comfortably over layers.
The Saguaro is a dropped fit vest meaning that this will fit about 2" lower than a traditional running vest. When hunched over in a riding position, the traditional style vest can put weird pressure on the front of the armpit, neck and push into the helmet. The Saguaro is designed to be most comfortable when in a riding position.
We’re working on expanding fit ranges in future versions. In the meantime, feel free to reach out with questions or sizing concerns. We want The Saguaro to work with your body, not against it.
HOW TO TREAT YOUR SAGUARO VEST
-
Hand wash cold, air dry. Apply Nixwax TX Direct if needed.

-
Do not bleach.
-
Ride. Keep riding. If it starts talking to you, maybe call it a day.

Seven responses to the same prompt, and seven very different options for those looking to carry some extra water, food, tools, or layers on their next ride. I've come to enjoy having a pack for rides of any length, as I can just throw it over my shoulder and know that all the things I need are in one place, instead of cramming my pockets anew each day.
Of the assortment on test here, my personal pick is the San Util Saguaro. The design packs a lot of utility into a simple form, and is comfortable on even the longest days. The chest pockets and main storage feel like the best executed versions thereof, and though I'd love to see some elastic straps for fluid fit, the rigid webbing holds fast once adjusted into place.

I’ve tried LOTS of MTB carry over the past few years. Hydration backpacks, vest, hip packs, etc. But the Saguaro Vest is THE BEST by a wide margin! I am a NICA coach, which means I have to have ready access to my phone to communicate with other coaches on trail, and also be able to carry a first aid kit and repair kit in case one of our student riders has a need. the Saguaro holds a ton without being bulky, it fits like a glove and the front pockets are the BOMB. I got the custom version…Ultra 400x and MCB EPLX600. Could not love this product more!
I love this product, it's my new favorite for epic rides and long races. I got it as a gift and wasn't really sure I needed it—I have an old camelback, I have a hip-belt. This is a much better system, both due to the way it doesn't shift around are harder section of trail and the way it allows you to fuel during the ride. The mesh backing allows you to fill your bladder with ice on a hot day and get an ice-sock cooling affect. It's also light, sort of like "everything you need, nothing you don't".
I’m a 6’1 large, curvy woman and this pack fits like a dream and holds all necessities, to include the excess snacks I will imminently pack. To be honest, I was skeptical it would fit or be comfortable given my size but the team at San Util NAILED it. It is easy to adjust, conforms really nicely, is incredibly lightweight, and breathes far better than I expected. It stays put and comfortable and adjusts easily while riding.
The storage is dialed and easily fits a med kit, tools, mini pump, and plenty of snacks. The front pockets are perfect for quick-access snack storage, which is obviously critical. I put the recommended 2L bladder in there and it’s actual perfection.
After several rides, my biggest takeaway is that I waited way too long to replace my old pack. If you’re debating between this and any other pack, don’t overlook this one. It’s seriously well thought out and extremely comfortable.
I custom ordered my pack for the most fun colors and it shipped two weeks later - impressive turnaround for a handmade in the USA product.
Got the vest out for the first time this weekend. Loaded it down pretty heavy for the White Rim and was impressed with how well it carried the load. The fit was great with some minor adjustments (5’8 150lbs). Chest pockets were very convenient and the main pocket had enough room for all the stuff necessary for a 10hr desert excursion. Carried a total of 4L water in the pack. 2L bladder as well as 4x 500mL soft flasks (2 in chest pockets and 2 in bladder compartment). I recently used a USWE pack and the Saguaro was more comfortable, carried the load better,and had more room/functionality. Based on initial impressions the San Util quality seems higher than USWE. Excellent vest.
I've tried a number of other vest prior to the Saguaro Vest and I can say this one takes the cake. I can wear this thing all day and all night with zero issues. It breaths well and fits like a glove when it's empty, full, or anywhere in-between.
I used this vest all summer on long runs and long bike rides. A few weeks back I did a ~60 mile mountain bike ride with this and it was perfect. I did a ~20 mile run with this pack and it was also pretty perfect. I've done some more technical scrambles with it and I don't see why it wouldn't work on big multi-pitch stuff. Point is that this is really well designed and I wish I had one sooner. To the folks complaining about no clip...the buckle thing slides through most bladder tops, then you loop the little piece of webbing over the buckle. Simple and it works (and I assumed that's what it was for!)
This is a great vest. In the past I have used a BD running vest for bikepack racing and adding a little more food capacity for big days. The saguaro is durable, looks pro and less running dorky, as well as having good storage and pockets. It’s perfect for high alpine riding in southern CO, I plan on using it for the CTR next year. One change that would make this a 5 star review is if they added a stretchy ultra mesh back to the vest instead of the daisy chain webbing. That would be way more functional, I don’t trust the webbing to hold onto a light rain jacket and I can’t easily shove a bag of chips and a banana into it at a resupply. I’m trying to find someone with a barrel sewing machine to retrofit it!
best hydration pack i've ever had. fits soooo much better than any Camelback I've had. been using it for moto and MTB in 2026. the side straps are great for changing the fit so it fits snug around chest protector. highly recommend
I really like the basic design and fit of the vest. It’s light and much less cumbersome than typical full size Mtn biking packs. Two things however I have noticed that personally I think would improve the pack. Some type of closure at the top above the bladder. The other would be a small clip or strap that attaches to the top of the bladder keeping it from collapsing down into the pack.
Great vest! Very comfortable.
I'd been eyeing the Saguaro for a long time and I am so glad that I ended up buying it. After trying several vest style packs it takes the cake. It is by far the most comfortable fit I've experienced, all while bringing the perfect amount of storage for solid days on the trail bike. I cannot recommend this pack and San Util designs enough.I'll be a lifetime user.
I purchased this to run in (instead for for riding) as I couldn't find any big name outdoor brand running vests that I liked or that fit. This vest is perfect! Just what I was looking for. The perfect amount of storage, pockets and a bladder for longer runs.
Got my first ride in with this vest and was pleasantly surprised by how weightless it felt, it’s barely noticeable once you’re moving. I’m still a little skeptical about the bladder compartment not having any kind of closure. It looks a bit odd sticking out of the top, but I think that’s something I’ll get used to over time.
I’ve tried a bunch of packs and hip bags this spring, and this one is easily my favorite so far. Feels like I’ve finally found the winner.
They nailed it. I use it for mountain biking in the Salt Lake area. I tried pretty much every other MTB hydration vest/pack out there and this is the only one that checked every box. I have a 46 inch chest, and this adjusts comfortably to fit me, even with layers. I also love the strap length over the top of my shoulders which allows this to sit at a natural position on my back. Premium cottage company build. Reminds me of products I have from ULA or HMG. Durable zippers? Check. Big front strap pockets. Check.I also love the side opening main compartment. This means you can access the storage while only removing one shoulder strap, not both. Hydration pouch access/securing is brilliant. It's obvious to me now after owning this that there is no reason to have the hydration pouch compartment behind a velcro or zipper. Whoever designed this gets that. And then shock cord for carrying layers. 10/10 review from a gear guy with high standards.
Like supporting a smaller maker. Seems great so far. Have used on several rides. Pockets and straps thoughtfully designed. Materials seem quality. No complaints.
I love love love this vest. It has the section for the water bladder, tons of pockets and zipper compartments to stow away all of my on the bike snacks and necessary extras needed for long rides. I love the daisy cord stretch when I overdress I can just roll up my jacket and tie it to the ouside. Easy to adjust to fit your own body composition. Thanks San Util for a another great product.
I’m really enjoying the new vest. I’ve had others from USWE and High Above. They were both really good, but the San Util is the most dialed: fit, durability, ease of use, carrying capacity and layout are all perfect. Really pleased with it.
I can't say enough about how great this vest is! I used it on a 100+ gravel race and it was great! I could carry enough water and nutrition in the pack and have room for a jacket. However, it was in June and definitely didn't need one. In saying that, I never felt that it made me hot either when wearing it. Which i have found with other vests. I love the pocket on the outside as wel, lets you store things you may need to get to easily.
I’ve tried it all over the years and this vest is fantastic. The 2 L size gives it more flexibility than smaller vests. It rides great and the little extra storage goes a long way. Great job on the design Adam!
Stoked I made this purchase. It’s big enough for some longer missions, while still being comfortable enough to want to wear on shorter outings.
Ample storage for bike tools, nutrition and a rain jacket - I’ve maxed this sucker out space wise and it’s more than you think.
Very adjustable so you can continually dial the fit depending on what you’re carrying.
100% recommend. Biking, running, this vest does it all!
This pack is amazing! From carrying all my spares and keeping my jersey pockets empty on long rides, to also being very well ventilated so I don't overheat and being comfortable to wear for long periods of time. This pack truly does it all and even has plenty of spare room for my vest, arm warmers, leg warmers and every other gear accessory you want to bring. Best part is, it doesn't bounce around while descending even when it is filled up and it does not restrict my heavy breathing on long climbs with the adjustable straps to fit to me. I also love how easy it is to keep my nutrition up front so I can easily access it while riding. Truly amazing!!
To say I love this vest is an understatement!! It has accompanied me on several trail runs, hikes, and Mtb rides.the specialized pockets on the front are perfect for your nutrition/quick snacks. The back compartment holds just the right amount of gear I need. Also, it’s always tough as a female finding the “perfect fit”. This vest hugs me perfectly and doesn’t rub or move when I’m on the trail. 12/10 would recommend!
