Active Skin 4L Hydration Pack Set keeps hydration close and bounce low on fast-paced trail runs
What Our Gearhead® Experts Are Saying:
"This vest is my go-to for short to mid-distance trail days. The fit is super comfortable with zero bounce, and I love that it includes two flasks up front. The quick link strap makes it easy to adjust on the fly, and I don’t feel overheated even when temps rise."
When our runs start to stretch beyond an hour, the Salomon Active Skin 4L Hydration Pack Set gives us just what we need without adding bulk or weight. Designed specifically for women, this 4-liter hydration vest brings race-ready fit and all-day comfort together in one trail-focused package. The Sensifit™ construction adapts to our movement, hugging our torso with breathable stretch mesh that feels like it’s barely there—no bounce, no hotspots, just flow.
We get instant access to hydration with two included soft flasks that stay secure in redesigned chest pockets, and space in the rear for a 1.5L reservoir if we’re pushing extra miles. Stash essentials in the back compartment, quick-access front stretch pockets, or the secure zip chest pocket, and clip on a set of poles with Salomon’s custom quiver compatibility. Lightweight, thoughtfully designed, and trail-tested, the Active Skin 4 keeps our essentials dialed so we can stay focused on the terrain ahead.

Great 1st Hydration Vest
This is the first hydration vest I've used. I originally thought the flasks would be removed from the front pockets to drink, but then saw a video review and realized they stay in the pocket. It is super easy to tilt my head down and take a sip. The vest fits securely without any bounce.

Would buy again
I bought this as my first ever running vest. I am using it with one or both flasks that come included with the vest, depending on the length of my run. So far I have used it on runs up to 18 km. The vest fits well, it doesn't move around while I run and I don't get any chafing (my chest measurement is exactly in between sizes S and M but I decided to go for the larger size, I am normally a size 10 with most brands). It is so much more comfortable to wear than my running belt, and it is a game changer to be able to bring more than just a small amount of water on my runs. I really wish I had bought it sooner! Since it does add an extra layer, it does feel slightly warmer to run with the vest but it is made from breathable material. For runs in warmer weather, I like to put the filled flasks in the fridge overnight before my run so the cooled water in the flasks acts as 'cooling elements' for a while, plus I feel like cool water makes me feel hydrated faster. I have only owned the vest for a bit more than a month so I can't judge how durable it is, but the material and how it has been assembled looks like it will last for a long time. Overall I would definitely recommend this product!

Great hydration vest
I'm a small person and the vest fit perfectly. It was soft and light and dried quickly once I took it off. I really like the water bottles in the front pockets because they're easy to refill.

Love the fit
Appreciate that it doesn't move around on my long runs. I wasn't sure about sizing but went with my usual size and found the fit to be perfect.

Love
I bought this in anticipation of training for a 40 mile race and it was exactly what I was looking for. Excellent fit (36 DDD chest, bought the XL), and very light but still able to pack what I needed for runs. Highly recommend.
