- Who it's for
- Runners and mountain-goers who need to carry meaningful supplies on longer efforts without being weighed down or restricted. Notes also flag it as a good fit for petite or female frames, as sizing runs true rather than skewing large like typical unisex gear.
- What people are saying
- Hosts consistently praise the no-bounce fit, light weight, and generous, easy-to-access storage. One note from a habitual belt user confirms it avoids the constricting feel common to vests.
- Worth noting
- The updated neck construction is soft and chafe-free, and stretchy mesh pockets make on-the-move access easy. One host flags brand enthusiasm for Tantrums as a start-up, which is a personal preference rather than a product attribute.
Matthew Barrera's review
I use this vest for longer days in the mountains and 14k summits. It’s extremely light, comfortable, and functional. Plenty of storage for you if you want to move fast through the mountains and not get weighed down by too much pack.

I just got this vest after reading reviews on Reddit. So far I have used it on my training 25k run, where I was self-supported. I used the included flasks, one filled with electrolytes and one with water. I was also carrying 5 gels and a few chews, as well as my phone and car keys. Everything was easily reachable, nothing was poking in, and there was no bounce. Usually I am a belt user as I find vests a bit too constricting, but the Crest 6 was a perfect tool for a longer self-supported run. I could see myself using it for a run commute or a day hike as well.

The revamp of this vest is great, the neck part is soft and doesn’t cause scratching or chaffing. If you are a woman or more petite framed this vest runs true to size which is nice as most unisex gear is typically based on men’s sizing. The storage is excellent and the stretchy mesh allows you to easily grab whatever you need.

This thing fits like a glove. No bounce means no significant chafing, and it holds HELLA supplies. Love the ease of use and lightweight feel. Once it's on you can just enjoy the run!

For any long adventure that requires a pack this is the most breathable and simple option. It stores everything I need without fussing with too many pockets. It breathes as well as any pack I've tried. I also love supporting start-up brands and Tantrums is as cool as it gets.
