DOWN OR SYNTHETIC

Insanely light summer bag which uses the highest fill power down available, +900, the Passion One also packs down to an astonishingly small 18 x 12cm diameter. The quality of construction is excellent but the real performance is in the down, as it is the highest possible quality then (providing it is allowed to loft correctly) it will deliver the highest warmth to weight ratio.

The lightest sleeping bag option from Mont-Bell, this 'climbers bag' functions very well as part of an ultralight sleeping system when the UL down garments are integrated or cached in your pack in case of an emergency bivouac. Stored loose and well lofted at UOG to retain the down's full lofting capability which is what keeps you warm.

Excellent Summer bag without a hood - but with a zipper that goes all the way down one side and round the boxed foot - this means it can be laid flat - ideal if you're the kind of person who doesn't like being trussed up in a sleeping bag. With a fill power of 800+ its a quality bag, the best quality bag with the full length zip round opening, sleeping bags in this category are often 'sewn through' construction this one has H baffles - so its warmer given its weight.

At just 1 lb 3 oz., the SummerLite is the lightest bag we make in a continuous baffle construction. Our goal in designing this bag was to make it as light as possible without eliminating key features or function. The result is a fully-baffled bag that weighs only 19 ounces and features a full-length zipper with insulated draft protection! The SummerLite is a dream come true for lightweight backpacking fanatics.

With their ankle-length zip fastener, lowest weight and pack size there is excellently plenty room left for sleeping. With a weight of 25g/sqm the Yeti Rip Stop nylon fabric is still extremely tearproof. Thanks to the calendered manufacture of the fabric, good wind- and water-proof characteristics are achieved as well. The high-quality filling is gained from extremely large Masurian (Poland) breeding geese.

The Micro series are our lightest weight bags, fully-featured and filled with 850+ Loft Eastern European Goose Down. These bags incorporate our 2D NanoShell providing the lightest most breathable water resistant shell.

Designed with a contoured mummy shape, the Micro series is the lightest and most compact sleeping bag in its class. With a unique drawcord opening at the foot for effective temperature regulation, the Micro series can be converted from an open duvet to a technical box foot mummy sleeping bag.

Ultra light. Absolutely first class. Compact, almost impossibly light, quality materials! SupCell, a film thin nylon material that weighs under 30 g/qm, is used for the tear- and light water resistant exterior shell. This, when combined with the best in pure down filling (95/5, 800 cuin Loft) and a special baffle construction, is the secret that makes the warmth-to-weight ratio possible.

If your summer bike tour is going to take you through different climates then the UltraLite is a good choice. With a 59" shoulder girth this efficient bag is good to -7°C. The full down collar helps to seal in heat around your neck without adding excess bulk, and 455g / 16 oz. of high lofting down pumps this bag to 5". The total weight of this very compressible package is only 820g.

The Neutrino Bags are aimed at lightweight end users - where every gram counts. the Neutrino bags are ideal for fast&light mountaineering, cycle touring, mountain marathons and ultralight backpacking.

Incorporating our 2D PermaShell™ fabric and a premium 650 loft down, the Trek bags are a refined classic. The 60/40 fill ratio in the Trek bags is maintained using a side block baffle and differential cut shell. In the top of the shell a 3D side wall, a feature normally reserved for technical alpine sleeping bags, provides more space for the down to loft right to the edge of the bag.

An all new Trapezoidal vertical baffle system with Flowgate technology that has been uniquely customised for Rab is used to provide very efficient warmth and the best possible use for the 850 fill European goose down that we use.

The Alpinlite would be a good choice if you find standard mummy bags to be too restricting around the shoulders and foot. The continuous baffle means that down can be shifted from the bottom of the bag (where it can get crushed) to the top of the bag for maximum loft. The shifting process is performed by 'flicking' the bag in the appropriate direction.

The Kodiak sleeping bag is extra large in every sense - with lots of room to accommodate larger people, or just those wanting more room. It also comes in a 7' length.

The Antelope GWS sleeping bags have a Gore Windstopper shell because this makes them more water resistant and so you are less likely to get the down inside the sleeping bag wet - which would be a disaster. Our advice is that if you are using a two skin tent then you should not need the extra protection of a water resistant fabric - however if you are using a bivy or tarp, or if you are going to extremely wet conditions, we would recommend you take a water resistant bag such as this.
