A soft-sided, 42mm-threaded water bottle that packs down to nothing and takes filters, but doesn't fully replace a hard bottle for hot days or bottle pockets.

A field review of the classic LifeStraw straw filter: 57g, no batteries, but is drinking-from-a-straw the right call for backpacking?

Katadyn Micropur Forte MF 1000F Review
A dual-action chlorine + silver ion purification liquid that treats 1,000 L per 100 ml bottle. Best for travel, water tanks, and as an ultralight backup purifier for clear backcountry water.
Osprey Hydraulics LT 2.5L Reservoir Review
A feature-rich, lightweight hydration reservoir built for Osprey packs. Great closure and mid-hose quick-disconnect, with minor trade-offs in drying ease and taste break-in.

A classic, BPA-free HDPE bottle in sizes from 30ml to 1000ml — versatile, leak-proof, and a reliable trail staple, though not the lightest option available.

Nalgene Wide Mouth Ultralite Bottle (32 oz) Review
The Nalgene 32oz Wide Mouth Ultralite cuts nearly half the weight of a standard Nalgene using HDPE, making it a compelling pick for cold-weather and UV-purification setups.
Platypus Big Zip EVO 3L Review
The Platypus Big Zip EVO 3L offers best-in-class flow rate and clever QD hose design, but recurring QC complaints around leaks and component durability temper the enthusiasm.
LifeStraw Peak Series Solo Water Filter Review
The LifeStraw Peak Series Solo is a 1.7 oz squeeze filter for ultralight hikers and trail runners. Compact and fast, but bottle compatibility is trickier than it looks.

The HydraPak Stash 750ml is a collapsible TPU bottle that packs to 2 inches tall and stands upright when empty — a capable backup or travel bottle with real ergonomic trade-offs.
CamelBak Crux 3L Reservoir Review
A reliable, well-priced hydration bladder with excellent flow and a no-fuss design — but its weight and screw-top cap hold it back for weight-conscious backpackers.

The Thermos Light & Compact 1L is a reliable, well-built insulated bottle for day hikes and commutes, but its 510g weight gives serious ultralight packers pause.
Sawyer Micro Squeeze Water Filtration System Review
The Sawyer Micro Squeeze is a 57g hollow-fiber filter that splits the difference between the Mini and full Squeeze — lighter than the Squeeze, faster than the Mini, and versatile enough for almost any setup.
Platypus QuickDraw 1L Filter System Review
The Platypus QuickDraw 1L Filter System is a fast, ultralight hollow-fiber squeeze filter with a field-checkable integrity test — a strong Sawyer Squeeze alternative for solo backpackers.

Sawyer MINI Water Filtration System Review
The Sawyer MINI delivers proven 0.1-micron filtration at just 2 oz and ~$25, but its slow flow rate and needy maintenance routine make it a better fit for casual and solo hikers than daily thru-hiking grind.
