Product Insights
The Sage Active Skin 4 Hydration Jacket is a women-specific vest that combines the stability and fit of Salomon's premium ADV line—using the same SensiFit mesh, dual sternum straps, and women's-specific shaping (shorter back, princess seam, curved straps)—with a more accessible price point ($125 CAD, $45 below the ADV Skin 5) and lighter weight (255g with flasks, 20% lighter than the ADV Skin 4). The tradeoff is a firmer, less pliable SensiFit mesh that eliminates bounce but feels less supple than ADV's softer version, and a pocket layout that concentrates all seven front pockets on the chest (no side pockets) for quick access during runs up to 50K, with the rear pocket requiring two hands to open. Core strengths include collapsible 500ml HydraPak flasks that eliminate slosh, one-handed adjustment via cord locks and the Quick Link sternum strap, and durability from materials proven in higher-tier vests, earning it a #1 rating from Trail & Kale.
Verified claims
- Value
- Sells for $125 CAD, $45 less than the ADV Skin 5, while using the same SensiFit mesh and dual sternum straps.
- Storage and pockets
- Seven accessible pockets—two flask pockets, front stretch compartments, a zippered pocket, and a large rear compartment—support 4L loads; no side pockets.
- Fit and feel
- Weighs 255 g with flasks (often listed as 257 g/9 oz), about 20% lighter than the ADV Skin 4, with firmer SensiFit mesh that stays gripped; sizing generally follows ADV models, though minor fit differences are possible.
- Flask pockets
- Dedicated flask pockets provide stable one-handed access to the included 500ml HydraPak flasks.
- Front pockets
- Small zippered chest pocket holds keys and gels and can fit some smaller phones, with a reviewer reporting an iPhone in the pocket; most current standard smartphones, such as the iPhone 14, are too large. Front stretch pockets keep gels and small valuables accessible.
- Rear pocket
- Rear back pocket is large enough for a waterproof jacket and has an integrated key loop.
- Pocket layout
- Seven accessible pockets; no side pockets concentrate all quick access on the chest.
- Weight
- Weighs 255 g with flasks (officially listed as 257 g/9 oz), about 20% lighter than the ADV Skin 4, for a barely-there feel.
- Stability
- Collapsible flasks eliminate sloshing, and SensiFit delivers a bounce-free fit.
- Capacity
- 4L capacity is ideal for runs up to 50K without extra bulk.
- Price comparison
- At about $100 USD ($125 CAD), the Active Skin 4 costs $45 USD less than the Salomon ADV Skin 5, with two flasks included.
- Fit quality
- SensiFit and the elastic sternum strap deliver a bounce-free fit, using the same fabric and strap system as Salomon's $145+ vests.
- Drinking
- Bite valve delivers strong flow and the flask collapses as you drink, eliminating slosh.
- Convenience
- 42mm wide opening accepts ice and powder; the flask is top-rack dishwasher safe.
- Construction
- HydraPak flasks: 65% TPU, 23% PP, 10% silicone, 2% POM, weigh 51g each, with RF-welded seams; can be frozen solid and withstand liquids up to 60°C.
- Distance range
- 4L storage, flasks, optional bladder, and trekking poles enable 50K runs.
- Fit adjustments
- Front cord locks and an elastic sternum strap enable one-handed tightening and unrestricted breathing while running.
- Bounce control
- SensiFit eliminates bounce during runs but is less pliable than ADV's softer mesh.
- Adjustability
- Salomon's Quick Link dual sternum straps and chest toggle allow one-handed on-the-fly adjustment, with elastic sections that expand during breathing.
- Mesh snag resistance
- Stretch mesh shoulders are breathable but less snag-resistant than rugged fabrics.
- Flask durability
- HydraPak flasks are abrasion-resistant TPU, withstand standing on, and are dishwasher-safe.
- Overall durability
- Uses the same SensiFit fabric and Quick-Link straps as premium Salomon vests, and is ranked #1 by Trail & Kale.
- Trekking pole loops
- Integrated rear loops let you carry collapsible poles hands-free.
- Expert endorsement
- Ranked #1 hydration vest by Trail & Kale, used as go-to pack.
- Sizing consistency
- Size mapping generally follows the ADV Skin 12, though minor fit differences are possible; the vest uses the same SensiFit fabric and Quick-Link straps as higher-tier Salomon vests.
- Liquid capacity upgrade
- Adding a compatible 1.5L reservoir doubles liquid capacity to 2.5L without reducing the 4L gear volume.
- Unisex fit
- The official product page lists this Sage model as a unisex running vest with unisex XS–XL sizing; Salomon also makes a separate women's-specific version, but this Sage model uses the unisex fit.
- Flask material safety
- The included Hydrapak flasks are made from TPU, which is inherently BPA- and phthalate-free; any faint new-plastic smell rinses away after a few washes and is not reported as a lasting taste.
- Vest care
- The vest is hand-wash only; Salomon specifies hand wash cold (30°C) with no bleach, iron, dry cleaning or tumble drying. The flasks can be hand-washed with warm, mild soapy water and air-dried upside down.

A hydration vest for trail and road runs
This hydration vest is aimed at runners who want to carry water and essentials on trail runs, with one reviewer calling it their go-to for most trail runs and another assessing it as excellent for short to medium runs on roads or trails. Its stretch, breathable, and strategically padded fabrics are designed to be easy to wear, and the chest toggle and sternum strap let you adjust the fit quickly on the fly, with elastic that makes it easier to breathe as you pick up the pace.[1,3,4,5,6,7]
Hands-free hydration on runs
Carry water on your run with the two included 500 ml (17 oz) Hydrapak flasks, which sit in front chest pockets so you can grab a sip on the go. The flasks have a high flow-rate valve for easier drinking while moving. For longer outings, the vest is also compatible with an additional 1.5 L reservoir carried on the back, sold separately.[1,3,6]
Carrying trail running essentials on long runs
This 4L hydration vest is built for runners who need gels, a phone, keys and a spare layer on hand without extra bulk, with reviewers describing it as suitable for trail runs up to a 50k ultra. Front stretch and zipped pockets hold small items like gels and your phone, a large rear pocket fits layers, and a key loop keeps keys secure. Pole loops let you carry trekking poles when routes call for them. Note that storage is in the front and back pockets—reviewers point out there are no side pockets on this version.[1,2,4]
Staying visible on dark-weather workouts
Made for runs or walks when light is low, this Salomon jacket has reflective details intended to help keep you safe and visible in the dark. A hidden emergency whistle in the left chest pocket adds an option for attracting attention if needed.[6]
Product comparison
Compared within this brand.
| Sage Active Skin 4 Hydration Jacket: Choose this if you want a lightweight, vest-style hydration pack for trail running: it includes two 500 ml (17 oz) Hydrapak soft flasks in quick-access chest pockets, takes an optional 1.5 L reservoir in the back, and offers a 4-litre capacity that reviewers found well suited to short or medium runs and even up to a 50k ultramarathon. It is built for a women's fit with Salomon's SensiFit construction, breathable inner mesh, adjustable cords and sternum strap, and weighs about 257 g (9 oz). One caveat: it has no side pockets, and one user felt its back pocket offers slightly less space than the ADV version because of the zipper.[1,2,3,4,5,6] | Grvl Skin 4 Hydration Vest: Choose this if you want a lightweight, minimalist gravel-running hydration vest that comes ready to go with two included 500 ml (17 oz.) Hydrapak soft flasks in front pockets designed for quick, no-fumble access. Its Quick Link system lets you tighten or loosen the chest fit on the move, and a reviewer reports less heat buildup than vests with denser back panels thanks to its more open, breathable mesh back. Note that the front-loaded design prioritizes fast access over maximum storage volume, it's described by a reviewer as a lighter, simpler, more hybrid option rather than a replacement for Salomon's Adv Skin 5, and this listing only offers X-Small, Small, and Medium sizes.[8,9,10] | Adv Skin 5 Hydration Vest: Choose this if you want a lightweight, fitted 5-liter hydration vest for demanding endurance runs — it includes two 500 ml (17 oz.) Hydrapak flasks with easy front access, weighs about 7 ounces, and can take an additional 2 L reservoir in the back. Reviewers report using it comfortably on runs and races up to 100 miles with no bounce, though it has fewer pockets than the previous model (side pockets swapped for a stretchy lumbar sleeve that some reviewers liked for jackets and gloves but missed for small essentials). Note that sizing is unisex in XS to XL with no women-specific model, and the mesh can feel slightly abrasive against bare skin, so plan to wear a thin shirt underneath.[11,12,13,14,15,16,17,18,19] |

Comparison of Salomon Active Skin 4 vs ADV Skin
Friends have active skin 4 and difference to adv is noticeable. Sides don't have pockets, while ADV has a pocket all around. I think there is also bit less space on the back (it has zipper).
