World-renowned ultra-runner Scott Jurek designed the SJ Ultra Vest to be the the ultimate pack for any occasion. Featuring the best volume to weight ratio of any pack ever made, the 7.5 ounce Scott Jurek Ultra Vest can carry a half-day of gels or bars in the easily accessible front pockets, along with a unique expandable or compressible main compartment utilizing Cuben-Fiber, for a total capacity of an amazing 9.2 liters. Options to carry trekking poles and an ice axe complete the package.

"I’ve been using Ultimate Direction packs for years, modifying them to carry bottles in front…the Ultra Vest is the culmination.”

5 of 5 Great fit May 30, 2014
Reviewer: Richard Gannon from England United Kingdom  
I recently bought the SJ vest for my Wife. She loves it! Training with it most days in prep for her next long trail race coming up! The fit is great, comfortable with easy access to bottles and pockets. Well done me for choosing it :)

5 of 5 Race vest April 28, 2014
Reviewer: Russell Morling from Maidstone, Kent United Kingdom  
First time I have purchased anything from Ultramarathonrunningstore. Got a call a few days after placing order for previous model of race vest. Advised out of stock but told latest version would be sent at no extra cost. I saved over £20, great customer service. Will defo use again in the future. Great range of products as well!

4 of 5 Best running bag I've ever used March 11, 2014
Reviewer: Adam Leadbetter from Cheshire United Kingdom  
I've had this bag for a couple of months now, but this weekend I used it in anger for the first time at the Bolton Hill Marathon. It carried full kit, water and food brilliantly.

when I first bought it, I was amazed by the lightness of the materials and the design aspects. It took me a while to dial the fit in - I'm right on the bottom end of the medium for chest size but as I'm taller than average for my width I didn't fancy a small. Using the full length of the rails for the straps sorted everything out though.

I'd definitely buy another (although maybe a v2.0) but I do have one or two minor gripes, hence the loss of a star. The gel pockets to the side of the bottle holders don't hold on to gels when you take a bottle out - at least not High5 gels. Maybe Gu or Clif with their shorter packets would stay in better. The phone pocket on the shoulder doesn't hold on to my phone (Samsung Galaxy Ace) so it doesn't quite work as advertised.

5 of 5 Useability February 28, 2014
Reviewer: Mark Robson from Bangor, Down United Kingdom  
A wonderful vest with great pockets and access ... And I love the stretchiness too. Well balanced too so it doesn't feel restrictive. Very glad I bought this !

5 of 5 Great item February 15, 2014
Reviewer: Robert Beech from Birkenhead, Merseyside United Kingdom  
Bought this for ultra runs and have tested it out already.  What a great item.

The kicker valves on the bottles in particular are brilliant once you get used to them.

Cant fault the item
