The Stratos 36L Daysack from Osprey is a rugged and ready pack that boasts unrivalled storage and carrying comfort for its size and weight. The adjustable AirSpeed™ suspended mesh back system keeps weight directly off the back for maximum load spreading and impact absorption. The adjustable torso length and hip belt create a secure and tailored feeling fit, with 36 litres of storage and a top and bottom dual entry system providing ample, easily accessible storage space for a day’s adventure or weekend escape.
as per spec. Seems comfortable but not used it yet

Having exhausted myself looking at back pack features, took the plunge and bought Osprey. Great features and warranty, but you need to select a size based on your size and probably need a partner to adjust fit when you first get it. Slightly surprised that I had to resort to YouTube to fit it.
