Panniers supplied with horizontal compression straps on the outside of the bag can be used to tighten the bags around the load in each pannier. This provides ability to make the bags smaller and provides more secure handling as the weight of the load in the panniers is much less likely to shift around in the pannier. A particularly important consideration for use on a front rack.
I have been using my Delta Compact Panniers for their ease of use for taking off and putting on the bike and have come to appreciate the simple design. Although I have found these to be my go to panniers for quick grocery and business errands I didn't like the way they handled on a front rack when fully loaded on my touring bike. This was due to the lack of features previously described. So while browsing several different makes and models of panniers looking for these quality options I stumbled upon some excellent panniers from Trek on sale at one our local shops.
