Rab Men's Storm Bivi

Product Information

It’s no-frills, but no-frills is sometimes fine if the bag is light and protective, and that’s certainly the case here. Top: 40D ripstop nylon with PU coating (108gsm) with fluorocarbon-free DWR HH: 10000mm MVTR: 10000g/m2/24 hrs As Rab’s cheapest and lightest bivvy, this is well suited to campers looking to ditch the tent for the first time. The Trailhead is crafted from hardwearing 40 Denier ripstop nylon with a breathable yet waterproof polyurethane coating on both its top and base. This durable combination ensures that any rain is kept at bay, while a zipped mesh vent enables appropriate ventilation. All seams are taped, completing what is an impressively watertight product. The Storm Bivi is constructed with a breathable 40D ripstop nylon on top and 70D nylon at the base, with a PU coating for rugged, waterproof protection. The fabric is treated with a fluorocarbon free durable water repellent (DWR) which helps to create extra resistance against elements like rain and wind, whilst being a more sustainable choice than your average bivi. Fluorocarbon free finishes are much more eco friendly as they don't use any chemicals that would cause harm to the environment.

This thing’s made from Pertex’s impressive Diamond Fuse fabric, a 2.5-layer ripstop nylon with specially shaped yarns that are intricately woven together to create a robust, abrasion resistant and highly durable fabric – one that’s both waterproof and highly breathable too. It’s certainly a distinctive product due to the high, clam-shaped opening at its head, which utilises a single arcing pole to create a high (for a bivvy bag) ceiling. This makes for easy entry and exit and gives the user plenty of head space – after all, no one wants a claustrophobic bivvying experience. The material the product is made from is often a sign of the quality for shelters & bivis. Take a look at the product details over at Cotswold Outdoor to get a feel for this.
