For those of you with the Ultralite + skull cap, do you have any issues with rain pooling on the roof? Used mine for the first time in France last week and every time it rained I had a pool of water on the top left of the bivvy where the peak is. Also had a small pool a little further back but main issue was at the front where the peak is.
Thanks

It can do this especially if you are on very level ground / perfectly crafted swims as the peak is effectively parallel / dead level . . .personally have never like the peak and preferred the skull cap on the original; they are superfluous in a headwind anyway and only provide vague additional footwell protection if the rain is coming directly down or from behind. . .
Only ways to alleviate are
1 - Make sure the skull cap is as taught as possible (pull it hard before velcro attachment at every location)
2 - Slide your throwing stick between the skull cap and bivvy at the front (I've always stored mine here anyway and also store my pult here with the pouch dangling outwards on the opposite side of the door opening) and angle the handle back on itself to raise the void area between the peak and bivvy - this lifts the fabric and helps the water run off.
3 - Spray the skull cap / peak area more frequently with Fabsil to ensure the DWR is constant and beads water well (continued pooling means this area 'wets out' quickly) I leave mine on constantly and never take it off (one of the Ultralites benefits)
4 - If all else fails poke the peak periodically with your finger from the underside and the water will drain off in the side gutters
5 - Its hardly an issue - constant rain is depressing whatever bivvy you own! I remember spending a week in a 2man Armo with extended wrap in France when it rained heavily ALL week . . . water pooling was the least of my worries - being bivvy bound / damp and blanking was way worse!
