This is the current version of Alpine Bivi Bag which differs from the old one only in the packaging which now states 'Rab' and not 'Integral Designs by Rab'.
It will appeal to those who are looking for maximum performance and a slightly larger capacity balanced with a smaller pack size made with event® waterproof fabric with durable a 70 denier nylon base.
It differs to the RAB Ascent Bivi by being supplied WITHOUT the removable bug mesh, plus it is slightly wider across the chest by 10cm. It uses a lighter weave of eVent in the upper skin but has the same waterproof non breathable base.
The result is a saving of almost 200g (against the RAB Ascent) and a much smaller packed size of 10cm x 30cm.
The additional 10cm width will be of interest to those with a broader chest, or with winter sleeping bags who want maximum loft.
A superb 'lightweight' bivi bag and as the name suggests ideal for Alpine trips.
