Rainsmore hydration backpack – insulated 18‑litre with 2‑litre bladder (dark green)
This pack is made for days when staying hydrated and keeping your kit dry actually matters. Thoughtful but not fussy — an 18‑litre bag that takes a full 2‑litre bladder, enough layers and snacks, plus room for the usual bits and bobs that always seem to go walkabout. Built from hardwearing polyester with reinforced stitching, it stands up to scrapes and knocks whether you’re off on the trail or cycling into work.
Key features
- Includes a 2‑litre soft water bladder tucked into an insulated rear compartment to help keep drinks cool for hours — proper handy on scorchers and steep climbs.
- Quick‑access hose outlets on both shoulder straps (left and right) so you can sip without stopping; internal buckles stop the bladder sloshing about.
- Compact 18‑litre capacity for essentials: spare layers, a compact first‑aid kit, snacks and devices. Two front zip pockets and two side mesh pockets for bottles or a slim brolly.
- Two levels of weather protection: splash‑resistant fabric for light showers and a removable rain cover stored in a hidden base pocket for heavier downpours.
- Comfortable carry: breathable, lightly padded back panel, adjustable chest strap with an emergency whistle and reflective trims for low‑light visibility.
- Handy extras include a removable phone/sunglasses pocket, helmet buckle, trekking‑pole loops and an elastic external cord for bulkier kit.
When to use it
Perfect for day hikes, cycle commutes, trail runs and climbing approaches. If you’re fed up of faffing about with bottles, this makes hydration simple — sip on the move and keep everything else tidy. It also suits short overnight trips where you want a light, organised pack rather than a heavy expedition rucksack.
Dimensions and materials
Made from durable polyester with reinforced stitching. Approximate dimensions: 26 x 16 x 45 cm. Weight: around 800 g. The included 2‑litre bladder is soft, food‑grade material. The back panel is breathable and slightly padded to cut down on rubbing and improve airflow.
Practical care and tips
- Rinse and air‑dry the bladder after each use to avoid odours; store it separately if you can.
- Use the internal buckles to stabilise the bladder and prevent movement while running or biking.
- Pull the rain cover from the bottom pocket when the weather turns — no more soggy kit mid‑hike.
- If you’re unsure about fit, tweak the chest strap and how you pack the load before setting off on a long day.
Some wonder about long‑distance comfort — this isn’t a heavyweight rucksack replacement for multi‑day loads, but for day trips, rides and short overnighters it’s a brilliant, no‑nonsense companion. Comfortable, protective and designed to take the faff out of staying hydrated, so you can get on with the fun bit.
