The Short Answer
Tool belt or tool vest? A tool belt is better for heavy loads and maximum capacity when you work on the ground. A chest rig (tool vest) is better for ladders, tight spaces, and taking weight off your lower back. Many tradespeople run both and switch by the job.
With Holstery, you don't have to pick one system. The ModBelt HD (16.2 oz, padded) and the ModRig chest rig (14.5 oz, holds up to six holsters and pouches) use the same 1.75" clip, so your holsters and pouches move between them in seconds. Both are assembled in the USA and backed for life.

Tool Belts: Built for the Long Haul
There are many trades and even more ways to carry tools. The right setup affects your speed, your comfort, and how you feel at the end of the day. Here's where a tool belt earns its spot.
Higher weight capacity
A tool belt rides on your hips, which handle heavy loads well without straining your upper body. For trades that need a lot of iron on hand, a well-fitted belt with good pouches keeps the weight low and stable all day.
More storage space
A full belt setup with pouches, and suspenders on heavy days, holds a big volume of tools and materials. That makes it a natural fit for framing and finish carpentry. With a modular belt like the ModBelt HD, you change the layout by clipping pouches and holsters on and off, not by buying another belt.
Industry familiarity
Tool belts are the long-time standard on most job sites, so there are more pouch and accessory options for every trade and budget.
Where belts fall short: all that weight sits on your hips and lower back, and wide pouches catch on ladder rungs and get in the way in tight spaces.
Chest Rigs: The Climber's Best Friend
Better mobility at height
On a ladder or in tight overhead spaces, tools on your chest beat reaching around a holster at your hip. A chest rig keeps the tools you reach for most right in front of you, with less twisting and less shifting your weight. One verified ModRig buyer said it works well "no matter if I'm up on a ladder or in a tight cupboard." (Dean S.)
Less lower back strain
Moving weight off your waist takes pressure off your lower back. Many tradespeople who've carried loaded belts for years find a vest cuts their end-of-day fatigue. "It's way more comfortable than hanging stuff from my waist," said one ModRig buyer (Ulysses M.).
Stays put when you move
A snug chest rig moves with your body, so it doesn't sag or dig in when you crawl, kneel, or work in confined spaces.
Where chest rigs fall short: less total capacity than a fully loaded belt, and a panel on your chest can run warm. One reviewer said the panel against his body was "not breathable at all" (Mike M.). Your upper back also does more of the work, as another buyer noticed: "I do feel my mid-back muscles working harder but it is usually my lower back that suffers" (Melinda C.).

Which Is Better for Your Back?
According to OSHA, a fully loaded tool belt can weigh upward of 50 lbs, which puts significant strain on your lower back and hips. OSHA recommends carrying only the tools the task needs, and using padded belts and suspenders to share the load between your shoulders and waist.
A chest rig takes that idea further by moving the load to your chest and shoulders. If your lower back is what hurts at the end of the day, a rig is worth a serious look. If you carry heavy loads, a padded belt with suspenders may suit you better. Either way, carrying less is the biggest win.
If you already deal with back pain, talk to a doctor or physical therapist about what's right for you. For more, read our Top 5 Health Benefits Of A Light Weight Tool Belt.
Can a Modular Rig Handle Heavy Hammers?
It's one of the most common questions about going modular for framing. A modular setup can carry a hammer in a dedicated holster like the Jolly Roger, an angled holster that stops the handle from slapping your leg.
For a heavy framing hammer you swing all day, most framers keep it on the belt, where the weight rides low on the hips. Clip the Jolly Roger to the ModBelt HD, add a Big Joey on a LowBoy for nails, and use suspenders on heavy days. Save the chest rig for the tools you need up high.

Run Both With One System
Many experienced tradespeople keep both: a tool belt for heavy production days and a chest rig when the job calls for mobility. Some combine them, with a few holsters on the rig and a light pouch at the hip for overflow.
With Holstery, that's easy. Every holster and pouch uses the same 1.75" clip, and ModSlots on the ModBelt HD and ModRig lock them in place. Move your TapeMaster from your belt to your chest in seconds. You don't need two sets of gear.

Common Concerns
"A chest rig can't carry enough."
It carries up to six holsters and pouches, enough for most service, electrical, and ladder work. For heavy production days, pair it with a belt or switch to the ModBelt HD.
"Will a chest rig be hot?"
It can be, since it covers part of your chest. In hot weather, a belt keeps your chest clear. Many people switch to the belt on the hottest days.
"Do I need two sets of holsters?"
No. Every Holstery holster and pouch fits the ModBelt HD, the ModRig, and any belt up to 1.75" wide. Here's how to move holsters between ModSlots.
"Will a tool belt shift when I bend?"
With a heavy load, any belt can shift. Balance the weight on both hips, and use the ModBelt HD's suspender attachment points on heavy days.
