Rides like a dream

  • Familiarity: I've used it several times

I have been getting out to the desert since mid Feb my TR's range from 8 to 20 miles this vest fits like a glove and allows me to bring extra food and clothing in case of changing weather. Best one Ive ever owned!!

UltrAspire Omega for President

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

I was looking for a larger pack for Spring/Fall all-day solo unsupported backcountry trail runs and tested three packs against each other: UltrAspire Omega, UltrAspire Titan 2.0, and Nathan VaporAir. The Nathan carried just how I like it - high up on my back and not floppy or bouncy even when bombing downhill under a full load. However, it just wasn't large enough to carry everything I would carry on cool-and-possibly-inclement-weather long runs. The Titan 2.0 was plenty roomy, but super floppy and hard to keep from bouncing when running downhill. Also, the load carried too low on my back. This wasn't much of an issue when I was walking on the uphills, but it got really aggravating on the downhills to be constantly tightening the pack and changing my stride to keep it from bouncing around.
Enter the Omega. Plenty large enough to hold my gear (see below for the full list), great pocket selection to organize said gear, rides high up on my back, and minimal bounce when bombing downhill even with a full hydration bladder. I especially appreciated there being two side straps and two sternum straps for dialing in the fit, the stiffeners on the zipper to give the pack some rigidity, and the high placement of the drinking tube keeper. And the two extra stash pockets on the back! I've got about two hours under full load with this pac so far and I'm loving it!
For comparison, this is what I've had it loaded with during the test and what I usually bring on early/late season solo runs: full 70oz. bladder, wind breaker, fleecy sweater, arm warmers, leg warmers, warm cap, thin gloves, emergency blanket, electrolyte pills, tube of first aidy pills, vet wrap, compass, phone, personal locator beacon, matches, knife, thin gloves, sun screen tube, water purifying drops, headlamp, spare batteries, 8 bars and 8 gels.
