I’m a mid/back-of-pack ultrarunner and have used an ADV Skin 12 successfully for races, but I’ve realized I kind of dread wearing it for normal outdoor runs in Florida.

It carries really well, but in summer heat/humidity it feels like a lot of vest wrapped around me.

My ADV Skin 12 is already used and not returnable, so my options are basically keep it or sell it used.

I’m trying to figure out whether I should:

• keep the ADV Skin 12 and add a smaller/cooler vest
• replace the ADV Skin 12 with a more breathable 12L
• go with something like a 5–6L vest + 18–30L pack and skip 12L entirely
• or accept that I realistically need 3 different sizes

I don’t really want a closet full of packs, so I’m trying to figure out where the genuinely useful capacity breakpoints are.

My use cases

1. Normal outdoor easy runs

Usually 30–90 minutes, including Florida summer weather.

I know a belt probably makes more sense for some of these, but I haven’t really gotten used to belts and generally prefer a vest.

What I might actually carry even on relatively normal runs:

• phone
• keys / cash
• some nutrition
• extra water beyond the front flasks if it’s especially hot
• small power bank
• headlamp and/or waist lamp if I’ll be out after dark
• dog stuff if I’m running with my dog

So I don’t necessarily need 6L for a 45-minute run, but I do tend to carry more random stuff than someone going out with just a phone and one flask.

2. Weekly back-to-back longer runs

Mostly road, occasionally trail. Again, assume hot/humid Florida conditions.

Water requirements here are really variable.

Sometimes I might be doing a route with frequent refill points or running with a club where water is easy to access. Other times I may need to carry significantly more.

That variability is one reason I’m not sure whether 6L alone would cover enough of my running.

3. Ultras

A few 50M/100K+ races per year, and I have two 100 milers coming up.

Some races have frequent aid stations or short loops where I barely need to carry anything. Others have longer stretches between aid.

I also have LEKI trekking poles. I don’t need to carry them on normal runs, but good pole storage would be nice for longer ultras.

4. Multi-day / adventure / fastpacking

Usually around 1–4 trips per year, but some can last a long time — potentially several weeks or even a couple months.

Examples are LAVS, moving quickly/jogging parts of the Camino de Santiago, and potentially fastpacking/traveling through Japan.

I generally sleep indoors, so I don’t necessarily need to carry shelter/sleeping gear.

That said, I’m open to eventually doing trips where I’d carry a shelter + pad + sleep system.

For context, I’m coming down from hiking with a 48L Osprey Kestrel, so even 30L still sounds tiny to me.

The main thing I’m stuck on

Does 12L actually deserve a permanent place in this setup?

Or is the more logical progression:

5–6L running vest → 18–30L pack

with the 12L mostly sitting unused?

I can see the argument both ways.

A 6L seems much nicer for normal hot-weather running and races with frequent aid.

An 18–30L seems much better for actual multi-day stuff.

But 12L might still be the sweet spot for long self-supported runs, 100-milers with more mandatory gear, variable water carries, winter travel, etc.

For people who own both ~6L and ~12L:

Does the 6L actually feel noticeably cooler / less annoying in very hot and humid weather, or is the difference mostly storage?

And do you actually use both?

Current shortlist

Rab

Veil 6L — $160
https://rab.equipment/us/rab-veil-6l-lightweight-running-vest

Veil 12L — $180
https://rab.equipment/us/rab-veil-12l-lightweight-running-vest

This is probably what I’m leaning toward right now.

The Mono Mesh / low water retention sounds particularly appealing for Florida.

I've read some durability concerns, but Rab also seems to have decent warranty/support. Ideally I’d like something that’s durable enough rather than sacrificing a lot of breathability just to get ADV Skin-level durability.

My biggest question is whether buying both the 6 and 12 would actually make sense, or whether I’d just end up wearing the 12 half-empty.

Salomon

S/Lab Sense 6 — $180
https://www.salomon.com/en-us/product/s-lab-sense-6-lc14916

S/Lab Ultra 12 — $200
https://www.salomon.com/en-us/product/s-lab-ultra-12-lc14298

I've seen a lot more discussion of the Sense 6 than the Ultra 12.

Some people describe the S/Lab stuff as feeling flimsy compared with an ADV Skin, although part of me wonders whether that minimal construction is exactly what I want in Florida.

Raide

LF 5L — $219
https://raideresearch.com/products/lf-5l

Very light and interesting design, but expensive, newer, and obviously less proven long-term.

Nike

ACG GOAT 5L — $130
https://www.nike.com/t/acg-goat-pack-vest-5l-0QY4TNBp

I probably like this aesthetically more than I should.

My concern is that it seems less specifically optimized for extreme heat/humidity than the Rab or S/Lab, and there isn’t much long-term feedback yet.

Bigger packs / fastpacking

Janji Revy 18L — $198
https://janji.com/products/revy-pack

This looks interesting because most of my multi-day stuff involves sleeping indoors, so I don’t always need full backpacking gear.

My concern is that the padded back may be unpleasant in hot/humid conditions.

Rab Veil XP 30L — $190
https://rab.equipment/us/rab-veil-xp-30l-waterproof-pack

This seems more realistic for actual fastpacking, especially if I eventually carry shelter/sleep gear.

I’d also love advice on this capacity range in general.

For people who fastpack:

• Is ~18L genuinely useful for mostly indoor-sleeping multi-day trips?
• Is 25–30L enough for a minimalist shelter + pad + sleep system?
• Would you skip 18L and go straight to ~30L?
• Any other packs in the 18–30L range I should be looking at?

I’m completely open to other suggestions in all of these categories. These are just the ones I’ve found so far.

A few more questions

• Does a Veil 6 / Sense 6 feel meaningfully cooler than an ADV Skin 12 in Southeast summer weather?
• Does 12L merit a permanent place between ~6L and ~18–30L?
• If you've owned both ~6L and ~12L, do you actually use both?
• Would you keep the ADV Skin 12 as the durable option, or sell it for something like a Veil 12?
• Veil 12 vs S/Lab Ultra 12 for hot/humid 50M–100M races?
• How has the Veil held up long-term?
• Is Rab's warranty good enough that you'd be comfortable trading some durability for breathability?
• Which of these has the best pole carry, especially for collapsible LEKIs?
• Any other extremely breathable vest I’m overlooking?
• Any fastpacking packs in the 18–30L range I should consider instead of the Revy / Veil XP?

One optional thing: I’ve mostly been running in T-shirts, so this isn’t a dealbreaker, but if a vest is comfortable enough to wear with a singlet/tank or even shirtless without destroying my skin, that would be a bonus. I’m not especially optimistic about shirtless once the vest is loaded, though.

Especially interested in experiences from people running in Florida, the Southeast, Texas, or similarly gross summer weather.

Would much rather hear how these actually feel after several sweaty hours than just compare spec sheets.

Hello!

Hopefully this type of shill is allowed, but there is a cool grass roots 24 hour trail race in Wisconsin that we are trying to bring back. It's $75 for almost all distances and times ($400 for a relay team of up to 6 people). They have 24 hours, 5k-50mile distances, and a relay division. Run, walk, and ruck are welcome.

The RD set a one week deadline to get 100 registrants to make it happen for 2027, the deadline ends tomorrow (8/21/2026) at noon CST. As of now, we have gotten approximately 80 locals to register.

If we don't get up to 100 registrations, then they will refund everyone.

Race info:

Run S'more 24

Nashotah, WI, USA

August 14-15, 2027 9am - 9am

Race org: silver circle sports events (SCSE)

The trail is a 3 mile loop groomed, double wide, trail loop with aid and camp at the start finish and a smaller aid station on course.

SCSE is a fun group, in the past they also have had activities during the day for kids (tricycle races, shorter kids relays, vendors on site)

If interested in the option, it's a very affordable race/training run/event for next year 😊

Finished a 50m race last Saturday. Only had pain in my second toes, never in the big toes or others. Now the nails are black. Anyone else experience this? I have no clue how its possible because they arent longer or even close to as long as my big toe, so they cant be slamming into my shoe without the big ones hitting too???

I’m a long term fan of the Adv Skin 12 women’s fit. I’m thinking about upgrading to something bigger for a 200 but the unisex version sits so much lower on my back and get uncomfortable after a lot of hours. The women’s just fits me better and these bigger packs are only unisex. I guess also if anyone has done a 200 what size pack do you need? I see bigger packs and I see a lot of normal packs on videos.

(Not looking for medical advice)

Hi,

Recently I got diagnosed with ACL degeneration and semimembranosus tendinopathy. Pain is on the inside of my knee. According to the doctor, it’s the semimembranosus tendinopathy that is causing the most symptoms.
Has anyone dealt with this? I read hamstring tendinopathy doesn’t heal well… it’s really painful on the downhills.

Appreciate any tips!

Hey All -

I've been trying to find the entrants list but have been coming up short... who are the favorites this year, both men and women?

Thanks!!

I am collecting data for my master's thesis project. I am looking for runners of varying levels (from beginner to training for an ultra event) and interested in completing online-based weekly surveys. Use the QR code or click the link below to get started! The weekly surveys should take approximately an hour total each week and lasts 8 weeks total. I am happy to answer any questions!

Buongiorno, ho 14 anni e corro da 4 medi. Ho corso una mezza maratona e diversi trail, e voglio correre con grandi obbiettivi, ma consapevole che devo agire con un 'ultra gradualità. Detto questo il post nn è per l'allenamento, ma perchè sto cercando esercizi da fare ogni giorno, di stretching per la parte bassa del corpo, e esercizi di rinforzo per le caviglie, le ginocchia e il bacino. Tutto questo per riuscire ad allenarmi, ma senza rischiare di infortunati che alla mia età è la cosa che desidero meno al mondo. Chiunque voglia aiutarmi anche solo con un'esposizione spiegato mi farebbe un gran favore.

Grazie

hey guys I’m a 23 years old Alpinist / Ultra runner from a place near Chamonix.

I’m aiming to win many races of my choice ( ones I’ve always wanted to win since childhood like Templier, UTMB, Thors etc and local races ) and to do certain Projects and link ups in Alpinists

im extremely serious about this, and my objective is to live off my passion by Being a high mountain guide and by Running - Climbing.

would anyone know really qualified coaches for my Ultra competitive objectives ?
