Lightweight Carry for Minimalist Mountain Runs

Is the Raide Research LF 5L Running Vest good for ultrarunning?
Mostly. The Raide LF 5L is a lightweight, stable option for short ultras, mountain races and supported runs, with 5 litres of storage and two included 600 ml flasks. Its low-bounce fit and breathable build appeal, but limited capacity and occasional rear-closure issues make it less suitable for bulky mandatory kit or long stretches between aid stations.

What Is It, and What Changed?
The Raide LF 5L is a minimalist mountain running vest with 5 litres of storage, two included 600 ml HydraPak locking soft flasks and compatibility with a bladder, which is not included. Reviewers at RunToTheFinish, GearJunkie, RoadTrailRun and Outside praise its light, breathable Dyneema mesh base, stretch-fabric pockets and stable fit. It also has rear passthrough storage, pole-carry options and a removable ice-tool holder. The available review data does not establish a predecessor or a specific revision, so there is no verified change list to report.
How Does It Perform on Long Runs?
Reviewers describe a secure, low-bounce carry for road and trail running, with accessible bottle pockets and useful storage for mountain outings. At 5 litres, it is best suited to shorter races, supported ultras and routes with aid stations, rather than carrying a bulky kit list. Some reviewers report that rear-pocket snaps or closures can come undone under load, particularly downhill; pole stowing can also feel awkward, and a full load may affect comfort. Its single zip pocket is another limitation for runners who want more secure organisation.
Who Should Buy the Raide LF 5L?
Choose the Raide LF 5L if low weight, breathable materials and a secure fit matter more than carrying lots of kit. It suits mountain runners and racers who can keep their load modest, make use of aid stations and value the included flasks and pole or ice-tool carry options. At $219, it is a premium purchase, and the limited storage may not work for longer, self-supported outings. Check the unisex XS to XL sizing and your intended load, especially if you plan to carry poles or larger bottles.

Frequently asked questions
How does the Raide LF 5L Running Vest fit?
Reviewers generally praise the vest’s stable, low-bounce fit. It comes in unisex sizes XS to XL, but the review data does not provide detailed sizing advice. Check the sizing information and test the fit with your intended load, particularly if you plan to carry poles or larger bottles.
Are the Raide LF 5L’s pockets and closures reliable?
Reviewers praise the accessible pockets and versatile rear storage, but some report that snaps or closures can come undone under load, especially downhill. Pole stowing can also be awkward. The available review data does not establish long-term durability, so treat these as reported use concerns rather than a lifespan assessment.
How does the Raide LF 5L compare with its predecessor?
The available review data does not identify a predecessor or document changes between generations, so a direct comparison is not supported. It does establish that the LF 5L has 5 litres of storage, two included 600 ml flasks and mountain-specific carry features.
