If your talking about the pullups you can get in the supermarkets there ok, but only really for light or just in case use, they have standing leak guards but will still leak even after a moderate gush while sitting.
Ive had them leak a few times while driving, they feel very dry even when soaked and its hard to tell how wet they are due to there dark blue colour.
Personaly i much prefer the 'premium fit' there a bit more reliable but hard to find in my size.
