Best Bikepacking Gear Under 100 Grams

The Ultralight Philosophy

Weight savings in bikepacking follow the law of diminishing returns — dropping the first kilogram is easy, but every gram after that gets harder and often more expensive. However, some of the most impactful pieces of gear weigh almost nothing. Items under 100 grams tend to be small, simple, and specialized, but they can make a meaningful difference in comfort, safety, and convenience.

This roundup showcases our favorite sub-100-gram items across categories. Some of these replace heavier alternatives, and some are small additions that earn their weight many times over. All of them have been tested on real bikepacking trips, and none are gimmicks that sound good on paper but disappoint in the field.

Lighting Under 100 Grams

Nitecore NU25 UL — 28 grams

The Nitecore NU25 UL is the reigning champion of ultralight headlamps. At just 28 grams without the headband, it delivers 400 lumens of output from a tiny form factor with USB-C charging. The red LED mode preserves night vision for camp use, and the battery lasts up to 58 hours on low. This headlamp proves that excellent lighting does not require a heavy, bulky unit. It is our top recommendation for bikepackers regardless of whether they are counting grams.

Micro Rear Blinker — 10-15 grams

Tiny USB-rechargeable rear lights weighing under 15 grams clip to seat bags or jersey pockets for road and twilight visibility. Models from Lezyne and Knog in this weight range offer multiple flash patterns and enough battery for several hours. A 12-gram safety insurance policy is hard to argue against.

Sleep Comfort Under 100 Grams

Sea to Summit Aeros Ultralight Pillow — 60 grams

The Sea to Summit Aeros Ultralight Pillow transforms sleep quality at 60 grams. It inflates in a few breaths, provides genuine support for side and back sleepers, and packs down to the size of a small fist. Compared to stuffing a jacket into a stuff sack, the improvement in sleep quality is dramatic and well worth the weight.

Ultralight Earplugs — 2 grams

Two grams of foam earplugs can be the difference between eight hours of restful sleep and a sleepless night near a road, a river, or a campground with late-night neighbors. One of the most underrated pieces of bikepacking gear at any weight.

Sleeping Bag Liner — 80-95 grams

A silk sleeping bag liner adds 5 to 8 degrees of warmth to your bag while weighing under 100 grams. It also keeps the inside of your sleeping bag cleaner, extending time between washes. On warm nights, the liner alone can be your only covering.

Hydration Under 100 Grams

Sawyer Squeeze Filter — 85 grams

The Sawyer Squeeze water filter weighs just 85 grams and removes 99.99999% of bacteria and 99.9999% of protozoa. It threads directly onto standard water bottles or the included squeeze pouches. Flow rate is fast enough for on-the-go filtering, and the filter lasts for thousands of liters with proper backflushing. It is arguably the single most important sub-100-gram item on this list because it provides unlimited safe water access without the weight of carrying extra bottles.

Collapsible Water Bottle — 30-40 grams

A soft collapsible bottle weighing 35 grams adds 500ml to 1 liter of extra water capacity that takes up zero space when empty. Stow one in your frame bag for dry stretches and roll it up when you are near reliable water. Several companies make these, and they pair perfectly with the Sawyer Squeeze for lightweight filtration.

Tools Under 100 Grams

Tubeless Plug Kit — 20-40 grams

A dynaplug-style tubeless repair tool weighs 20 to 40 grams including a few spare plugs and saves you from needing to unseat a tire for most punctures. Just insert the plug from the outside, trim the excess, and ride on. These kits have saved countless trips from becoming walks of shame.

Quick Link and Chain Tool — 15-25 grams

A chain quick link (3g) and a compact chain breaker (15-20g) let you repair a broken chain trailside. A broken chain without a repair tool is a ride-ending mechanical. With one, it is a five-minute fix.

Patch Kit — 15 grams

Self-adhesive patch kits weigh about 15 grams and take up less space than a stick of gum. They back up your tubeless setup and spare tube, providing a last line of defense against flats.

Navigation and Electronics Under 100 Grams

Compass — 15-25 grams

A simple orienteering compass weighing under 25 grams is a reliable backup navigation tool that never runs out of battery. Combined with a paper map or basic terrain knowledge, it can guide you out of confusing trail networks when your phone is dead or your GPS has failed.

USB-C Cable — 15-20 grams

A short 15cm USB-C cable weighing 15 grams connects your power bank to your phone, headlamp, and other electronics. Carry one cable that charges everything instead of multiple proprietary cables.

Micro Power Bank — 70-95 grams

Compact 5,000mAh power banks now weigh under 95 grams, providing one to two full phone charges. That is enough backup power for a weekend trip, and the weight is negligible. Models with integrated cables save the weight of carrying a separate cable.

Clothing Accessories Under 100 Grams

Merino Buff — 45 grams

A merino wool buff weighing 45 grams is the most versatile clothing item per gram. It functions as a headband, neck gaiter, beanie, sun shield, dust mask, and emergency arm sling. The merino fabric resists odor for days and provides light warmth when you need it.

Lightweight Gloves — 35-50 grams

A pair of thin running gloves weighing 40 grams provides enough warmth for cold morning starts and chilly descents without bulking up your hands or compromising brake feel. Stash them in a jersey pocket or top tube bag.

Camp Items Under 100 Grams

Titanium Spork — 18 grams

A titanium spork weighing 18 grams handles every camp eating need. It is nearly indestructible, easy to clean, and will never rust or break. It is one of those items that seems trivial until you forget to bring it and have to eat rehydrated stew with a stick.

Ultralight Towel — 30-50 grams

A small packable microfiber towel weighing 40 grams handles face washing, dish drying, and emergency sweat management. It dries quickly when clipped to the outside of a bag during riding.

Stuff Sacks — 5-15 grams each

Ultralight silnylon stuff sacks weigh 7 to 15 grams each and keep your gear organized and protected. Color-coded sacks — blue for clothing, yellow for electronics, red for first aid — let you find items quickly in the dim light of a tent vestibule.

Storage and Organization Under 100 Grams

Top Tube Bag — 40-70 grams

A minimalist top tube bag or feed bag weighing under 70 grams keeps snacks, a phone, and small items within arm's reach while riding. The Ortlieb Frame Pack Toptube is slightly over 100 grams, but there are bolt-on options from smaller brands that slip under the wire.

Voile Straps — 27 grams each

Voile straps are the duct tape of bikepacking. At 27 grams each, these reusable rubber straps secure gear to your frame, fork, or rack with incredible holding power. Carry two or three and use them to strap a jacket under your bars, secure a water bottle to your fork, or improvise a repair. They are endlessly useful and nearly indestructible.

Adding It All Up

If you assembled every item on this list, the total weight would be roughly 700 to 800 grams — less than a liter of water. Yet you would have lighting, sleep comfort, water filtration, tool essentials, navigation backup, power, and camp convenience all covered. The point is not that every gram-counting item is necessary, but that careful selection of lightweight gear lets you carry more capability per gram than ever before.

The best approach is to identify which of these items solve problems you actually encounter on your rides. If you always struggle with sleep, the pillow and earplugs are revelatory at 62 grams combined. If punctures are your nemesis, a 30-gram plug kit is the best investment you will make all year. Choose the items that improve your personal bikepacking experience, and leave the rest. That is the true ultralight philosophy — not carrying the least weight possible, but carrying exactly what you need and nothing more.
