Onlar Multi by Buff — Wearing a Buff has an essential part of my training and Ultrarunning gear. I love the Buff brand! I got a Buff from Western States many yrs ago, and it's been a favorite go-to for races and inspiration.
Naked® Running Band by Naked Sports Innovations — I've been a Naked Band user since 2021. I think this is one of the best innovations during my 31 yr running career. I've still had the same band for several yrs, so the material is very durable. I had it re-stitched while I was in Taipei. I use the band for up to 3 hrs and can hold ~18 oz hard flask + 10 oz hard flask. I haven't tried the new bands (haven't needed to!), but I would imagine they're great. The Naked vests are also excellent for added capacity.
Nathan Push-Pull Cap 10 oz by RnJ Sports — Maybe I'm old school, but hard flasks with push-pull caps all the way! I've tried lots and lots of hard and soft flasks during my career, and I continue to prefer my trusty 10 oz. and 18 oz (insulated) Nathan hard flasks. <div>For daily runs of 30-90 min, I tuck the 10 oz flask in my Naked band, bra, half tights, or tights. I switch to an 18 oz insulated hard flask in the summer in AZ. </div><div>Then I add another 10 oz flask if I need to, or add a vest and more flasks if I need more capacity. In most Ultras I carry 2 x 10 oz hard flasks or 18 oz + 10 oz.</div>
