The Rab Ascent 300 Down Sleeping Bag is a great value lightweight down bag that packs well for a Font bouldering trip. The Ascent 300 is ideal as your first sleeping bag, or for regular campouts in milder temperatures, especially when you might get a little damp, and just light enough for short backpacking trips. Boasting an impressive feature set similar to that of a technical Rab bag, but without straining your bank account. The shape is slightly tapered giving more space inside especially if you sleep on your side or star-shaped. The highly weather-resistant shell is ultralight Pertex Quantum fabric that has a thin PU coating making it water-repellant so you stay toasty in a damp tent or bivvy and protects you from a clumsy tent mate with a cup of tea. The lofty 650 fill power duck down is treated with Rab and Nikwax's hydrophobic technology so the down stays warm when damp and comfortable in temperatures of 5°C and with a few thermal layers as low as 1°C. The deep insulated hood and draft collar add to a cosy night's sleep, keeping your noggin toasty when cinched tight. The full-length draft tube running the length of the zipper keeps out the cold on the zipped side of the bag and the two-way anti-snag zipper allows you to vent heat at the foot end. Finally, a small stash pocket comes in handy for your phone or torch for runs to the loo in the dark.
